Need help with indicators based on HeiKin Ashi

There are mainly 2 problems

1) when I loop through the rolling window of Heikin Ashi and tried to print the Close, I get 0 in the log

Related code :

for i in self.haWin:
self.Debug("haWin : {}<br>".format(i.Close))

2) when I compare the sma5 based on heikin ashi from the indicator and the number calculated by myself, they seem to be different.

self.Debug("the sma 5 based on Heikin ashi : {}<br>".format(self.sma5.Current.Value))

self.Debug("ha close : {}<br>".format(self.ha.Close))

I took the last 5 close price in the log, close prices are 33.9025,  33.8675,  33.805,  33.80875,  33.82, and the mean at  2020-05-15 15:58:00 is 33.84075(calculated by myself) instead of 33.877(in the log)

Thx

Hi Tai Man Chan,

(1) This error can be resolved by adding the `self.ha.CurrentBar` to `self.haWin` instead of creating a new TradeBar.

self.haWin.Add(self.ha.CurrentBar)

(2) This error is because the algorithm updates the SMA with each new candlestick and with each new HeikinAshi bar. See lines 19 and 38 in the backtest code above for reference. We can resolve this by creating a SimpleMovingAverage object in Initialize and only update it with each call to `hdUpdate`.

See the attached backtest which implements the changes listed above.

Best,
Derek Melchin
