I would like to write or let someone write an indicator for me. It should be simple i guess, it is based on a MA and a MACD histogram. The MA should change to color X if price closes above the MA and MACD histogram is positive. On the other hand it should change to color Y is price closes below MA and MACD is negative. Is there someone who can give me some advice on how to get started with this? Thanks!
R | API provides a whole framework for writing indicators yourself. Look at their API docs for more info.
