Zsyh9612Es ist gut, alle Websocket-bezogenen Codes zu kommentieren.

Nick_huangZ ist groß, können Sie mir sagen, wie Sie mit der Modifizierung positive Erträge erzielen können, und die Rückprüfung hat viel verloren.
Nick_huangKann man die Logik einfach erklären? Wie kann man auch etwas ändern, damit die Ergebnisse positiv sind?
BananenZ-Boss, bitte sehen Sie sich den Code von GetCommand an, der hier nicht zu verstehen ist, und die API ist nicht beschrieben, kann es verwirren?
KreatDie Analogplatte garantiert, dass der Kauf und Verkauf unübertrefflich ist, aber die realen Platten, die so häufig gehandelt werden, müssen nicht hängen.
HaixiongleeWarum ist die Datenanalyse gut, die Echtzeitoperation aber nutzlos?
BananenDanke, wir haben sie gefunden.
