from AlgoAPI import AlgoAPIUtil, AlgoAPI_Backtest
from datetime import datetime, timedelta

class AlgoEvent:
    def __init__(self):
        self.timer = datetime(1970,1,1)

    def start(self, mEvt):
        self.evt = AlgoAPI_Backtest.AlgoEvtHandler(self, mEvt)

        headers = {"user":"xxx", "apikey":"xxx"}
        self.app1 = self.evt.app_init("https://algogene.com/rest/v1/bot/76/pattern_recognition.signals", headers=headers)

        self.evt.start()

Step 3. Call library and Get Result

Use "self.evt.app_call(...)" to call my library and get signal indicator results (i.e. line #5-11).

In below example, we will

  • open a buy order if double bottom pattern appears
  • open a sell order if double top pattern appears

            res = self.evt.app_call(self.app1, params)
    
            # print result
            self.evt.consoleLog(res)
            
            # open order
            if res['double_bottom_pattern']==1:
                self.openorder(md.instrument, 1)
            elif res['double_top_pattern']==1:
                self.openorder(md.instrument, -1)
    
    def openorder(self, instrument, buysell):
        order = AlgoAPIUtil.OrderObject(
            instrument=instrument,
            buysell=1,
            volume=1,
            openclose='open',
            ordertype=0
        )
        self.evt.sendOrder(order)
