Apologies, this is a bit of a newbie question.
I am attempting to use indicator extensions for a calculation that also requires the absolute value of the MACD histogram. I keep getting an error message "TypeError: bad operand type for abs(): 'Identity", when I use abs() however. I've tried a few other things but keep running into the same issues.
Thanks everyone.

Hi David,
To do this, we can instead create a custom indicator object (e.g. SimpleMovingAverage) and update the custom indicator with the absolute value of our MACD indicator whenever our MACD indicator is updated. I’ve shown how to do this in the attached backtest.
Best,

Thanks very much for your help.
I've played around with the code and can't seem to get the desired numbers unfortunately. I'm a bit confused by the use of self.sma. Is this being used as a placeholder? Is it only storing the MACD line values, rather than the absolute histogram and signal values as well? I'm also trying to get this to work with a four hour timeframe on the AUDUSD ccy pair and need the values to work within a rolling window. Essentially the calculation I'm trying to get is (abs(macd histogram)/0.1) - ATR.
Further, do the Indicator Extensions not work with the ATR indicator? I'm not having much luck there either.

My apologies. Please disregard my previous query re: Indicator extensions and the ATR indicator. I've managed to get that to work.
