Hello eyeryone I am new to Quantconnect and I am trying to build a composite indicator by dividing the ADX by the ATR. To accomplish this I am trying to use the IndicatorExtension.Over() method. However I always get a TypeError telling me I am trying to acces a method that doesn't exist. Replacing the ADX and ATR indicators with an EMA indicator fixes the problem. Does anyone know why this happens and how to build the ADX/ATR composite indicator.
Thanks

Thanks for bringing this to our attention. After looking into this issue the IndicatorExtensions.Over() method currently only supports parameters of the IndicatorBase<IndicatorDataPoint> type and the indicator ADX is not of that type. We have identified the issue and it is on our TODO list have .Over() support all indicator types.
