哪位朋友可以把它做成MT4指标发布上来
https://www.mql5.com/en/forum/169873 I am using the indicator"TMAcentered MACD v1.2.ex4 " and I want toinclude it into my EA. But right now I got a problem, how can I determine thecurrent color of it programmatically ?regards,salexes Files:TMAcentered_MACD_v1.2.ex416 kb· Learn how to design a trading system by Bear's Power· Objects - Charts - MetaTrader 5 for Android· Murrey Math Line - Line Drawing Problem509salexes 2017.02.10 13:59 #1 Here is the source code of v1.0 which sadly redraws in history, theversion 1.2 attached in the above post does not do that, thats why I would haveliked to use it.
Maybe the code of v1.0 is enough to figure out how to detect the differentcolors. //+------------------------------------------------------------------+
