Working in production on Debian 10.
This is the Backtrader part of the project. MQL5 side of this project is located here: MQL5 - JSON - API
In development:
- Upload data on reconnect
pip install backtraderpip install pyzmq- Check if the ports are free to use. (default:
15555,15556,15557,15558)
See MQL5 - JSON - API documentation for better understanding.
You can create market or pending order with the default backtrader command.
self.buy_order = self.buy(size=0.1, price=1.11, exectype=bt.Order.Limit)If you want to cancel it.
self.cancel(self.buy_order)When you use bracket orders, one order with stops will be created on the MQL5 side.
self.buy_order = self.buy_bracket(limitprice=1.13, stopprice=1.10, size=0.1, exectype=bt.Order.Market)If you want to cancel bracket orders, you shold cancel only the first one.

[MT5 Terminal]/MQL/Files/Data
The example below downloads data for the past 6 months as tick data.

cerebro = bt.Cerebro()
data2 = store.getdata(dataname='EURUSD',
timeframe=bt.TimeFrame.Ticks,
fromdate=start_date
)
cerebro.run(stdstats=False)You can use any MT5 indicator directly from Backtrader via the MTraderIndicator class.

# MT5 inidicator name
indicator="Examples/MACD",

# Any omitted values will use the defaults as defind by the indicator

For a fully working and commented example of a Strategy refer to example.py.
This is an experimental feature and a work in progress! It WILL plot wrong data at this time.
You can open and draw directly to a chart in MT5 via the MTraderChart class.
def __init__(self, store):
self.bb = btind.BollingerBands(self.data)
chart = MTraderChart(self.datas[0], realtime=False)
indi0 = ChartIndicator(idx=0, shortname="Bollinger Bands")
indi0.addline(
bb.top,
style={
"linelabel": "Top",
"color": "clrBlue",
},
)
chart.addindicator(indi0)
