I want to use the heikin ashi data into the indicators, for example, i want to use the weighted moving avarage and the RSI also based to the Hekin Ashi data.
I've tried to wrote this:

self.sma=bt.indicators.SimpleMovingAverage(self.hk.close[0], period=self.params.speriod)

but is not working. Is giving me:

AttributeError: 'Lines_LineSeries_LineIterator_DataAccessor_Strateg' object has no attribute 'ha_close'

I've tried also in that way:

def __init__(self):
        self.ha_close=bt.indicators.HeikinAshi()
        self.startcash=self.broker.getvalue()
	self.ema=bt.indicators.WeightedMovingAverage(
		self.ha_close[0],period=self.params.period)

IndexError: array index out of range

And another question because on internet (https://backtest-rookies.com/2018/01/26/backtrader-working-heikin-ashi/) i found a tutorial that explain one strategy code but is using hk.close instead of ha_close that you told me.

P.S. I'm sorry if my question are so obviously for a lot of people. I'm pretty new and here is look like one of the only place that somebody can help me

Hi at all as you can see from the short description field can somebody explain me how to use heikin ashi indicator into a strategy. I was reading the documentation about the heikin ashi but i didn't understand how implement the indicator inside my strategy. Can somebody please help me?

Hi, at all, i'm new with backtrader and following the quickstart of the official page i've copied and paste some line of codes to try to understand how backtrader works. I'm not a programmer but i want to improve myself and learn. my problem i think for that i've understand is that it doesn't find the data. But i don't understand where i've to put the data. I've searched on internet and i've found another guy that has been the same problem (https://community.backtrader.com/topic/951/cannot-find-file-orcl-1995-2014-txt-from-the-quickstart-tutorial/4) but i didn't understand. I'll put below the output. Can somebody help me?
