The following is used for further explanation by way of a specific implementation scenario:
and receiving real-time price information of the product sent by a quotation engine, wherein the real-time price information of the product is USD/CNY-on-schedule, USD/CNY-off-schedule-1W, USD/CNY-off-schedule-1M, USD/JPY-on-schedule, USD/JPY-off-schedule-1W and USD/JPY-off-schedule-1M.
The following is defined in the configuration file: 2 service types: on-demand and off-demand; 2 product types: USD/CNY, USD/JPY; 2 fall point standard deadlines: 1W and 1M. When the system is started, the configuration file is read to generate 1 price receiving queue Q and 6 asynchronous processing queues list.
When Q receives the latest price of the quotation engine, the polling thread respectively stores the number into the corresponding 6 asynchronous processing queues according to the price type.
Each price type corresponds to a plurality of K lines, which are commonly a minute line, an hour line, a day line, a circumference line, a month line and the like. When a new price is stored in the list (USD/CNY on-demand), a K-line updating thread is distributed from the thread pool, the price type of the USD/CNY on-demand is locked, and then the thread is started.
A minute line, which is used for comparing the update time stamp of the existing minute line candle picture in the memory with the time stamp of the latest price in the list, if the time stamp is the same minute, the price in the list is compared with the four values of the opening price and the closing price (the opening price, the highest price, the closing price and the closing price) of the existing candle picture in the memory, and then the opening price and the closing price are updated; if the time is different, the candle icon in the memory is marked as the 'finished' state, the candle icon is written into the database, a candle icon object is newly built, and the four values of the opening, the closing and the opening are initialized to the latest price in the list. Hour line, update logic same minute line.
And the daily line, considering that the candle drawing period of one daily line is long, the loss of memory data caused by system abnormity is not avoided, and marking the daily line candle icon in the memory as an unfinished state every hour line warehousing, and warehousing synchronously. After one hour, updating four values of the opening, the closing and the updating of the date line candle picture in the last warehousing and the updating of the timestamp; if 0 o ' clock has passed the day, the state of the latest candle picture record in the updating database is ' completed ', and the updating of the record of the new day is started at the new candle picture object. Similarly, the candle drawing of the contour line and the moon line can refer to a sun line.
