  Did you try this? The indicator will try to automatically plo to the non-resampled data. To disable this behavior use the following during construction: _autoplot=False

  @soulmachine said in How to use two CommissionInfo inside a strategy?: Since data has only one name, so it's not possible to apply multiple commission fees? You're probably right. AFAIK a single commission could be specified per data name or default. As @run-out correctly mentioned - you may develop your custom commission scheme.

  @Jens-Halsberghe But in next(), you get a single OHLC bar which is a plain Python object, you can use math.log in def next()

  Moving average values at the very beginning are not defined by the moving average definition. Therefore nothing can be shown. If you want to show moving average value on particular bar, than you need to have 21 bar before this.

  No problem. But since this is a different thread that might help others, would you mind copying it into a new post stand alone with a good title? Thanks.

  @ab_trader Still stuck on this issue for a week now, anyway I could contact you on Discord/Telegram? In my head coming from a trading background this is so simple but I can't manually do the strategy fast enough for it to be viable..

  if the above code works, you should consider setting an init value for current_high in nextstart def nextstart(self): self.current_high[0] = self.data.high[0]

  @André-Tavares said in How can I inherit params from a parent class and append on the child class?: params.update({ No need to update the params dict. The parameters from the base classes are fused automagically by metaclass during the instantiation. You may take a look at the following post as well: https://community.backtrader.com/topic/2379/difference-between-params-and-p/2

  @Anthony-Chow said in Questions about EMA: Dayhigh = max(self.datahigh.get(size=num_bars, ago=0)) Try using bt.Max() as discussed here. This will evaluate the max at each bar in the line object.
