Diese Strategie ist eine Strategie, die vor langer Zeit auf der Digital Currency 796 Futures Exchange angewendet wurde. Futures-Kontrakte sind währungsbasiert, dh die Marge wird nach Währung abgezogen (z. B. werden BTC-Kontrakte durch BTC abgezogen). Die Strategie wird für das Lernen der Strategieentwicklung verwendet, die Logikverarbeitung ist immer noch sehr gut, und die Strategie wird hauptsächlich für das Lernen verwendet.

Strategie Logik
Nach dem Lesen des Strategiecodes können wir feststellen, dass die Strategielogik nicht kompliziert ist und es nicht viele Codes gibt, aber das Design ist genial und es kann an vielen Stellen als Referenz verwendet werden.
Die Hauptfunktion der Strategiehandelslogik ist dieloopFunktion, die wiederholt in der Hauptschleife dermainDieloopDie Funktion beginnt mit der Ausführung, platziert zuerst eine Orderposition, platziert dann einen Oder zum Stop-Profit und wartet auf die Erfüllung der Stop-Profit-Order.
- Ermitteln, ob die ausstehende Stop-Profit-Order vollständig ausgeführt ist. Wenn ja, also Profit, verlassen Sie die Detektionsschleife, setzen Sie die Logik zurück und beginnen Sie erneut.
- Detektieren, ob der Stop-Loss (Backhand) ausgelöst werden soll, aktivieren Sie den Stop-Loss, d.h. stornieren Sie alle ausstehenden Aufträge, schließen Sie die Position und setzen Sie dann die Backhand-Forward-Position oder die Backhand-Reverse-Position, um den Backhand-Auftrag entsprechend dem Parameter zu verdoppeln.
Die Strategie-Logik ist einfach beschrieben, aber es gibt noch einige weitere Details, wie die Festlegung der maximalen Backhand-Zeiten, die Erkennung der verfügbaren Kontovermögen und die Bearbeitung der maximalen Anzahl von Auftragsausfällen von 10 Mal.
Einige Funktionen in der Strategie sind so konzipiert, dass sie sich je nach verschiedenen Parametern unterschiedlich verhalten:StripOrdersFunktion,GetAccountFunktion,GetPositionDiese Funktionen haben je nach Parameterunterschied unterschiedliches Verhalten. Auf diese Weise wird der Code gut wiederverwendet, Code-Redundanz wird vermieden und das Strategie-Design ist prägnant und leicht verständlich.

Backhand-Doppeln birgt gewisse Risiken, vor allem in den Futures, die Strategie ist nur für Lernzwecke, Vorsicht beim echten Bot, bitte lassen Sie Ihre Kommentare und wir können eine Diskussion führen.
