can't get 2 timeframes to plot in 1 graph

joeyy

Hi all,

I'm trying to run a strategy that uses 1 indicator and 2 timeframes, 1 long for the strategy and 1 short for stoploss. I know backtrader already has a built in mechanism for stoploss but I want to use it for live trading too so I need to have control over what to send to the brokerage when that happens.

I have 2 candles one for 240 minutes and another for 15 minutes.
I can see the results plotted as 2 graphs, but I only want the longer timeframe to be plotted. More over, the buy and sell arrows should be drawn on the longer candle, which isn't the case.

plot

this is the relevant code

 # Create a cerebro entity
    cerebro = bt.Cerebro()

    # Add a strategy
    cerebro.addstrategy(EmaCross)

    data_ticks_long = bt.feeds.CCXT(
        exchange='binance',
        symbol='BTC/USDT',
        name='EMA 21',
        timeframe=bt.TimeFrame.Minutes,
        fromdate=FROM_DATE,
        todate=TO_DATE,
        historical='True',
        compression=STRATEGY_CANDLE_SIZE_IN_MINUTES)

    data_ticks_short = bt.feeds.CCXT(
        exchange='binance',
        symbol='BTC/USDT',
        name='STOP_LOSS',
        timeframe=bt.TimeFrame.Minutes,
        fromdate=FROM_DATE,
        todate=TO_DATE,
        historical='True',
        compression=STOPLOSS_CANDLE_SIZE_IN_MINUTES)

    # Add the Data Feed to Cerebro
    cerebro.adddata(data_ticks_short)

    cerebro.adddata(data_ticks_long)

    # Set our desired cash start
    cerebro.broker.setcash(STARTING_BALANCE)

    # Add a FixedSize sizer according to the stake
    cerebro.addsizer(bt.sizers.PercentSizer,percents=95)

    # Set the commission
    cerebro.broker.setcommission(commission=COMMISION)

    # Print out the starting conditions
    print('Starting Portfolio Value: %.2f' % cerebro.broker.getvalue())

    # Run over everything
    cerebro.run()

    # Print out the final result
    print('Final Portfolio Value: %.2f' % cerebro.broker.getvalue())

    # Plot the result
    # cerebro.plot(style='candlestick', barup='green', bardown='red')
    cerebro.plot()

I tried using plotinfo.sameaxis = True or plotinfo.plotmaster but it throws a
KeyError: <backtrader.feeds.ccxt.CCXT object at 0x7fe9e2959250>

Any help would be really appreciated!

I can always add this to show only the shorter timeframe graph

data_ticks_long.plotinfo.plot=False

so I guess my question is how can I get both the strategy line and buy/sell signals to show on the long timeframe graph instead ?
