Abstract

L'invention concerne un procédé, un dispositif et un système de traitement de données de transaction de devise numérique. Le procédé comprend les étapes consistant à : recevoir une demande de transaction pour une paire de devises à soumettre à une transaction, et déterminer un prix de transaction possible de la paire de devises à soumettre à une transaction (S0) ; déterminer si le prix de transaction possible tombe dans un intervalle de fluctuation de prix, l'intervalle de fluctuation de prix étant déterminé en fonction d'une valeur d'évaluation et d'un seuil de fluctuation de prix, et la valeur d'évaluation étant déterminée en fonction du dernier prix de transaction (S2) ; si ce n'est pas le cas, démarrer une période de réflexion (S402) ; après que la période de réflexion est terminée, exécuter les étapes suivantes consistant à : déterminer si un utilisateur annule l'ordre (S404), si ce n'est pas le cas, ajuster la valeur d'évaluation (S406), déterminer un nouvel intervalle de fluctuation de prix selon la valeur d'évaluation ajustée (S408), et déterminer à nouveau si le prix de transaction possible tombe dans le nouvel intervalle de fluctuation de prix (S410) ; si ce n'est pas le cas, redémarrer la période de réflexion, et répéter les étapes ci-dessus ; et lorsqu'il est déterminé que le prix de transaction possible tombe dans le nouvel intervalle de fluctuation de prix, déterminer le prix de transaction possible en tant que prix de transaction final de la paire de devises à soumettre à une transaction, et favoriser la transaction selon le prix de transaction final (S6). Une fluctuation de prix importante en un court laps de temps peut être efficacement évitée.
