Warum ein Handelszentrum?

Für den Marktzugriff gibt es REST und Websocket, und wenn die Websocket aufgrund einer Vielzahl von unwiderstehlichen Faktoren gezwungen werden, ihre Verbindung zu unterbrechen, müssen die Strategien Fehlerverhütungsmechanismen einführen. REST ist oft der stabilste Weg. Wenn Sie mehrere Strategien auf der gleichen Plattform, wie OKEx, haben und diese auf demselben Server ausgeführt werden, ist der Zugriff auf die REST API häufig begrenzt. Es gibt verschiedene Möglichkeiten, wie IP-Beschränkungen, Kontobeschränkungen oder eine Kombination aus beiden. Verwenden Sie ein Marktzentrum, um die REST-Anfragen zu reduzieren
