Could you please update this to allow for selection of data output. Currently, if the indicator chosen has more than one output this indicator will select the first output instead of user selection.
Secondly, once you chose the indicator you should be able the select the data source of that indicator. Currently if you chose MACD for example, the default data source is "close price". The user should be able to change this to anything including other indicators if capable, as the MACD indicator would allow is.
