Description

BACKGROUND OF THE INVENTION

1 . Field of the Invention

[0001] The present disclosure generally relates to systems and methods for aggregating, filtering, and presenting streaming data.

2. Description of The Related Art

[0002] Both public and private clouds have become increasingly popular computing environments. These environments, however, do not support streaming data due to variable latency between the host system and the remote operating system. In addition, the cost of pushing terabytes of streaming market data into various clouds incurs very high "transit" fees from providers, decreasing the value proposition of using clouds for data- driven applications.

[0003] Systems and methods for aggregating, filtering, and presenting streaming data are disclosed. In one embodiment, a method for presenting streaming data may include (1 ) receiving, at web services layer for a server comprising at least one computer processor, a query from a client, wherein the query comprises a plurality of parameters; (2) a data caching layer for the server receiving streaming data from at least one predefined streaming data source; (3) the data caching layer conflating the streaming data for each of the plurality of parameters; (4) the data caching layer aggregating the conflated data; (5) the data caching layer generating a snapshot of the conflated data by simultaneously running the query against the conflated data; and (6) outputting the snapshot to the client.

[0004] In one embodiment, the parameters may include a specific descriptor for at least one of a security and an investment.

[0005] In one embodiment, the query may further include an identification of a streaming data source.

[0006] In one embodiment, the streaming data may include market data.

[0007] In one embodiment, the web services layer may output the snapshot that is delayed by a predetermined amount of time, wherein the period of time is based on one or more rale associated with the streaming data.

[0008] In one embodiment, the method may further include an entitlement services layer for the server verifying that the client is authorized to access information responsive to the query.

[0009] In one embodiment, the method may further include

authenticating the client based on at least one client credential that is received from the client.

[0010] In one embodiment, the snapshot may be accurate for the at least one of the security and the investment for a certain time.

[0011] In one embodiment, the snapshot may include a proper state for the at least one of the security and the investment for a certain time.

[0012] According to another embodiment, a system for presenting streaming data may include a plurality of streaming data sources; a data loader for each streaming data source, the data loader receiving streaming data from the streaming data source; a data caching layer the receives the streaming data from the data loaders; and a web services layer comprising at least one computer processor in communication with the data caching layer. The web services layer may receive a query from a client, wherein the query comprises a plurality of parameters; the data caching layer may conflate the streaming data for each of the plurality of parameters; the data caching layer may aggregate the conflated data; the data caching layer may generate a snapshot of the conflated data by simultaneously running the query against the conflated data; and the snapshot may be output to the client,

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0027] Several embodiments of the present invention and their advantages may be understood by referring to Figures 1-4.

[0028] Embodiments are directed to systems and methods for aggregating, filtering, and presenting streaming data. [0029] In one embodiment, data from internal and external sources may be pushed into a high-speed data aggregation engine. Clients may make a simple web services request, specifying their credentials, source of information, and list of requested information. For example, in a financial institution, clients may submit a list of securities and fields. The client then receives a single response with the information that the client needs. This reduces or eliminates high-speed stream management that all applications have to support as well as the required infrastructure and development.

[0030] In one embodiment, any suitable aggregation engine may be used as is necessary and/or desired. In one embodiment, the aggregation engine may permit Structured Query Language ("SQL")-style content filtering on individual fields within data payloads, allowing for near realtime analytics on a wide array of products.

[0031] Embodiments may provide some or all of the following: (1) increased price advantage of Cloud-based applications through lower data transit costs; (2) large scale reduction of technology costs through decreased infrastructure requirements and shorter development cycles for data-driven applications; (3) more fungible developer workforce due to simplification of API and integration with spreadsheets; (4) advanced content filtering across disparate sources permits development of real-time application features that were cost prohibitive in the past; (5) facilitated distributed analytics through merging of external and internal data; and (6) the ability to age, or delay, the delivery of real-time data for individuals that do not need the data in realtime to reduce the cost of that data. Other benefits may also be provided.

[0032] In the financial industry, because market data and messaging involves a large amount of data, clients are expected to do significant work associated with dealing with payload coming out of the ticker plants. They often have to deal with hardware and software challenges related to large volumes of information, conflate it in order for users to derive benefits, aggregate across many threads and systems to support portfolio

management, etc. Embodiments address these and other challenges while giving end users and developers an interface with filtering.

[0033] Referring to Figure 1, a system for aggregating, filtering, and presenting streaming data is disclosed according to one embodiment.

System 100 may include a plurality of client access points 110, web services layer 120, data caching layer 130, data loaders 140_l5 140₂, ... 140_n, and data sources 150i, 150₂, ... 150_n. Data sources 150 may receive data from one or more streaming data source, such as internal and external market data, industry news, etc.

[0034] Although three data loaders 140 and data sources 150 are illustrated in Figure 1 , it should be recognized that a greater or fewer number of data loaders 140 and data sources 150 may be provided as is necessary and/or desired.

[0035] Data loaders 140 may receive data from data sources 150. In one embodiment, each data loader 140 may "feed" streaming data from one or more data source 150 into data caching layer 130. Each data loader 140 may further be in communication with web services layer 120. For example, each data loader 140 may communicate with control plane sendee 126, which may instruct one or more data loader 140 to create a new subscription, retry a failure, etc.

[0036] Data caching layer 130 may service requests from, web services layer 120. In one embodiment, data caching layer 130 may function as both a database and a message bus. [0037] In one embodiment, data caching layer 130 may also filter the data and may provide a "snapshot" of requested data.

[0038] An example of a suitable data caching layer 130 is the

Advanced Message Processing System (AMPS) from 60East Technologies.

[0039] Web services layer 120 may interface with clients using one or more client access points 1 10. In one embodiment, web services layer may provide sendees, such as configuration management sendee 122, monitoring service 124, control plane layer 126, and entitlement services 128. Other services may be provided as is necessary and/or desired.

[0040] In one embodiment, configuration management service 122 may provide configuration data for one or more data loader 140, such as what data sources 150 to connect to, how to connect to data sources 150, etc. In one embodiment, configuration management service 122 may provide run-time configuration information, for example, connection information (e.g., hosnport) for data loaders 140, web services layer 120, entitlement sendees 128, what data feeds to load, what web connections to support (http or https), SSL certificate locations, connection and thread pool sizing, logging intervals, environment (dev/test/prod), etc.

[0041] In one embodiment, monitoring service 124 may monitor a status of one or more data source 150, and may re-route requests if a data source becomes unavailable.

[0042] Control plane sendee 150 may interface with one or more data loaders 140. In one embodiment, control plane service 150 may pass directives between services, allowing both automated instructions (e.g., monitoring sendee 124 notices a failure of a data loader and instructs web service layer 120 to switch servers within data aggregation layer 130), or manual directives (e.g., an operations team wants to take a service offline).

[0043] In one embodiment, entitlement services 128 may verify that the client is allowed to access the data that is requested.

[0044] In one embodiment, client access points 1 10 may include, for example, cloud applications, local application, user interfaces, APIs, etc. In one embodiment, client access point 1 10 may provide, for example, a spreadsheet as its output to a client.

[0045] In one embodiment, system 100 may include the ability to provide a "subscription" for a client to receive updates. In one embodiment, updates to a complex query may be smaller in size than re-submitting the query, and receiving a full result set several times a second.

[0046] Referring to Figure 2, a method for aggregating, filtering, and presenting streaming data is disclosed according to one embodiment.

[0047] In step 210, a client may request information of interest, via an interface, such as a cloud application, a local application, an upload, etc. In one embodiment, the client may also provide credentials and identify the source of information and a list of requested information. In another embodiment, machine learning may be used to identify the sources based on past, queries,

[0048] In one embodiment, the client may use a web service protocol to request the information. The web service protocol may use, for example, SQL-like syntax for filtering information. An example query that may be submitted is "(/BID / /ASK >= (0.05 * /TRDPRC_....1) )", which means "where value of BID divided by value of ASK is greater or equal to 5% of the value of "TRDPRC_1."

[0049] In a financial system, the query may include an identification of a stock, industry, an field/area of interest, etc. The query may be used in filters.

[0050] In one embodiment, the request may be a subscription (e.g., to a stock, industry, etc.). In one embodiment, the request may specify a period or condition for each snapshot to be provided.

[0051] In step 220, the client may be authorized to access the requested data. In one embodiment, this may involve an entitlement check to determine if the client is permitted access to the requested information,

[0052] In one embodiment, the client may be further authenticated based on credentials that may be provided as part of the request.

[0053] In step 230, the request may be provided to the data caching layer, which, in step 240, may filter the data received from streaming data sources. The data caching layer may also "snapshot" the data, that is, provide a data state at a particular instance in time.

[0054] In one embodiment, business logic may reduce the number of fields of data that are presented to the client.

[0055] In step 250, the filtered data may be conflated. For example, data from more than one source that has been filtered may be aggregated. For example, in a minute, a stock may change in price from 70.00 to 70.05, back to 69.90 and up to 70.01. With a conflated source, client would only receive 70.01 since that was the proper state of the price at the end of the minute. This value, however, will not be the last value as it is not always the proper data point, in particular for a dataset with multiple fields, such as Bid and Ask,

[0056] In step 260, a data snapshot of the data may be generated. In one embodiment, a snapshot may be for a collection of securities, and may be accurate across that collection at that point of time. For example, the query may be r n simultaneously across the data thai has been aggregated (e.g., the securities of interest) rather than sequentially.

[0057] In step 270, the snapshot may be output to the client via a web application, local application, API, spreadsheet, etc.

[0058] In one embodiment, the delivery of the snapshot may be delayed by a predetermined amount of time in order to "age" the data. For example, the timing for data deliver}' may determine whether the data can be delivered for free, or if there is a fee for the data. Not all clients require realtime data; for example, an investment manager may not need real-time data when meeting prospective clients.

[0059] Thus, in one embodiment, the system may determine how long to delay the output of the snapshot, which may be based on rules associated with the data and/or the data source, and may delay the snapshot by at least this amount of time. In one embodiment, an auditable trail of the age of the data in the snapshot may be maintained.

[0060] Embodiments disclosed herein may separate the mechanics of the various processes performed by multiple lines of business from content that is relevant to solving the problem. That content, such as various lots in clients' portfolios, changes resulting from trades, money transfers, additions, withdrawals, etc. may be treated as generic internally published data, anonymized, and provided to one or more system/method for aggregating, filtering, and presenting streaming data. Examples of such a system/method are disclosed in U.S. Patent Application Ser. No. 15/378,501, the disclosure of which is hereby incorporated, by reference, in its entirety.

[0061] In embodiments, market data from various venues may be conflated inside of one or more system/method for aggregating, filtering, and presenting streaming data, and may be merged with portfolio information. As data goes through several merging stages, each lot becomes priced against real-time market data, then aggregated into a real-time portfolio views.

[0062] In embodiments, customers may use a custom rales engine to subscribe to "alerts" relevant to the business. For example, the system may send a notice to the client when a particular stock reaches a price threshold, when a concentration risk of a particular holding breaches a predefined level, when a valuation of the lot or portfolio rises/falls by a certain percentage, etc.

[0063] Referring to Figure 3, a strategic flow is provided according to one embodiment. Strategic flow mav include customers, a financial institution interface, a gateway service, one or more graphical user interface, a perimeter gateway, a Complex Event Processor (CEP) engine, an internal data platform (e.g., an internal data platform that may provide secure reliable messaging between publishes and consumers. Access may be provided using Open MAM A API), one or more market, data feeds (e.g., NASDAQ Basic, which carries NASDAQ and N YSE market data. A commercial feed handler may be used; OPRA, Pink Sheets, Trade Web, etc.), an Anonymizer a data injector, a security master, a portfolio management system, intraday activity monitors (e.g., intraday activity, order management systems, and cash flow systems), an alerting engine, and a notification platform. [0064] In one embodiment, the CEP engine may process data for applications that require market data and one or more of the following: (1) are in configurations that cannot support high-rate streaming data; (2) only require prices a few times a day but need those prices to have a very small hysteresis; (3) need to submit a large number of symbols at a single time (as opposed to streaming subscriptions that each take a single symbol); (4) aggregation of market and analytical data from a number of sources (e.g., Reuters RMDS, Direct Feeds, Internal Data, LOB market analytics); or (5) need the ability to filter the data on dynamic queries taking into account the values of one or more fields, or can use market data that has been delayed a determined time to lower its cost.

[0065] In one embodiment, the anonymizer component may strip identity of clients from portfolio contents prior to injection into the CEP engine. A reverse process allows processes to look up the ID associated with a specific client's portfolio they are interested in.

[0066] The data injector may provide a single interface to one or more technical assets. It may map reference data (e.g., symbology) between systems and communicate with both and an Internal Data Platform (e.g., to send portfolio information) and the CEP engine (e.g. ,to ensure instruments of interest are on the watch list).

[0067] In one embodiment, the portfolio management system may be the source of portfolio content data for clients' holdings. It may publish daily refreshes of portfolios of interest, publish portfolios on demand, as well as maintain the "official" start of day prices for all lots/portfolios.

[0068] In one embodiment, intraday activity monitors may monitor activity such as that originating from Order Management Systems, Cash Flow engines, etc. It may publish updates into the CEP engine as portfolio changes since start of day to reflect changes in valuation in real-time.

[0069] The alerting engine may translate client directions from the financial institution website into subscriptions against the CEP engine and other back-end systems. Persists alerts across days, listens for signals from the CEP engine that conditions were satisfied, performs desired actions, disables aciioried alerts, etc.

[0070] Figure 4 depicts an exemplary process flow according to one embodiment. In one embodiment, the data source layer may receive market data (e.g., market data streams) and may provide the data to the data loader layer, where it may be loaded into the data caching layer using one or more data loader. The CEP Engine may access the data from the data caching layer, and may provide configuration management, data filter processing, monitoring services, control plane services, entitlement services, etc. In one embodiment, the CEP Engine may provide services to customers via the customer access layer.

[00120] Price is in field MKT_PRICE_1

Data sets do not need to exist in the same CEP instance. For example, Data sets 1 and 3 may exist on the same CEP instance where the portfolio view is created. Data set 2 may be on another instance due to volume demands of ingestion.

[00122] An example portfolio design is provided. The portfolio may be stored in its own table, called Portfolios:

[00123] :

[00124] {

[00125] "portfolio" : "12345", "version" : 3.2.6,

[00127] "holdings" : [ [00128] { "source" : "Data Set 1 ", "security" : "JPM.N", "weight"

: 150 },

[00129] { "source" : "Data Set 2", "security" : "CLJ7.NYM", " weight" : 200 ) ,

[00130] { "source" : "Data Set 3", "security" :

"ISIN_USN82008AK46_MODEL,FUSE", " weight" : 2 } j

[00133] For example, portfolio pricing may se the following pseud o code:

[00134] for specific portfolio ID

[00135] for each asset identifier

[00136] total price ~ total price + (asset weight *

as setjpirce [as set identifier J )

[00137] return total price

[00138] In other words, a single value representing the real-time price of the portfolio, which will change as data changes, may be returned.

[00139] In one embodiment, there may be four layers of tables defined for both instances,

[00140] The first layer may receive data from market data publishers. For example, for both PortfolioPricing and CommodityFutures, there may be one table per data feed/source. On PortfolioPricing, these may be named "Equity" and "Bond" and on Commodity Futures, it may be named "Comm". These tables are not transaction logged nor replicated and the "shape" of the data in these tables is whatever that data source defines.

[00141] At the next layer is a replicated table that may be called

"AUPrices," which may act as the normalized union of price data from all sources. Data may be normalized and published to AUPrices from the Comm, Equity and Bond tables. In embodiments, this information may be conflated in order to reduce the maximum data rate.

[00142] The first step in the chain of actions may be to parse the underlying data and extract values of interest into variables. Extraction of values may be specified as a projection expression. For example when processing a message from Equity, the line

<Value>price=(/price/wBidPrice+/price/wAskPrice) / 2</Value> computes the average of the /wBidPrice and /wAskPrice and places the result in the variable { {price} } .

[00143] The next step of the action is to publish a new message containing the { {symbol] } and the normalized { {price} ), along with a "source" field that indicates the source of the pricing data. This may be published to the AUPrices table and may be formatted as JSON.

[00144] At this point, the incoming market data has been normalized and transformed into a single AUPrices table. Conflation and replication may be used to minimize the total volume of messages that the

PortfolioPricing instance has to deal with, while giving PortfolioPricing a complete view of all of the security prices needed to price portfolios.

[00145] Next, the portfolio may be modeled as a table "Portfolio", with one row per portfolio per security. Each message in Portfolio may have a portfolio ID, a security, and the weight of that security in that portfolio. This table is essentially the input data for the portfolios of interest, and the system may dynamically re-compute portfolio prices as the contents of the portfolio are adjusted, added, and/or removed.

[00146] This computation is done in the next layer, the aggregations. This may be modeled as two Views. The first view is a join between

Portfolio and AlTPrices, called "PricedPortfolio." There may be one message here for ever message in Portfolio, but because of the Join, current price for each security may be included.

[00147] A top PricedPortfolio may be the 2nd view that computes the portfolio price, "PricedPortfolioAgg." This is in essence a translation of the pseudocode (above) over to a view, containing one message per portfolio with the portfolio ID, the count of securities in the portfolio, and the SUM of the /price's/weight of the securities in the portfolio.

[00148] Thus, in embodiments, the system may receive portfolio data (e.g., by push), and then be receive queries/subscriptions to PricedPortfio and PricedPortfolioAgg to see the dynamically updated portfolio prices as the underlying market data changes.

[00149] In embodiments, each portfolio's official start of day valuation may be submitted as part of a daily load into a PortfolioRef table. This permits the PricedPortfolioAgg view to include a calculation of an unrealized start of day gain/loss by comparing current valuation and the reference data submitted into the PortfolioRef table. In one embodiment, a percentage change from start of day portfolio valuation may be calculated.

[00150] In embodiments, an alerting engine may set up subscriptions into the CEP engine that maps human-identifiable concepts to an underlying data structure. Arithmetic expressions and formulas in SQL language may he used to define when the alerting engine should receive a notification of an event. Upon data being received on a specific subscription, the alerting engine will map it back to a desired action (e.g., sending a message, such as an email or SMS, popping up a window on Advisor's user interface, etc.) and may execute that action. It may be further be configured to remain as an active alert, or disable itself by dropping a subscription.

[00151] Non-limiting examples of alerts include portfolio gain/loss above/below dollar amount or percentage, specific holding's value exceeds a specific threshold, etc.

[00152] Advisors, representing multiple clients, may maintain alerts covering multiple portfolios of interest for a holistic view of their clients' holdings.

[00153] At an organizational level, all holdings may be analyzed holistically in a CEP engine to facilitate hedging, cross-account stock loan, risk management, etc.

[00154] In one embodiment, cash may be represented in a portfolio as a number of units of underlying currency, such as the U.S. Dollar. Market data for the currency may be static (such as for U.S. Dollar for Dollar- denominated accounts), or represent current foreign exchange rates.

[00155] In another embodiment, a similar mechanism may be used for hypothetical modeling of portfolio changes. A separate CEP engine or a side table may be used to store the final representation of portfolio's hypothetical contents, while the same aggregation mechanisms can be used to price the portfolio. [00156] In one embodiment, a separate table in the CEP engine may store stock to sector relationships that may be used to build dynamic risk models to help customers manage risk.
