I am using Amibroker I wanna write a code that "xLine=EMA(40)", mainly BUY above xLine and SHORT below xLine For Long order placing.... Buy Immediately when High cross xLine But if same bar close < xLine, then (Cut Loss and Reverse) Sell and Short else if Cross(Low, xLine) then (Take profit and Reverse) Sell and Short For Short order placing, is exactly the opposite. Would you mind teach me how to write the code for the above action? Many Thanks!!!
