Hi all
Is the .ex4 option to make an indicator that can put a symbol on the chart instead of the mq4 placing a trade.More a visible trade function than a automated one..If so i dont seem to be able to make it draw an arrow with a standard macd crossover.Any help appreciated.

thanks

Hello,

".ex4" is a file extension. ".ex4" files are those that MT4 uses to run the strategy. Those are files compiled from ".mq4" source code files.

In MT4, expert advisors are used basically to trade, that's the idea. Indicators are used to draw something.
Well, expert advisors can draw objects if needed, for the idea to help you to understand what's happen with trades and orders... with trading. There is a block named "Draw arrow" that can draw simple arrow when it is executed, so you can use it if you want.

Just to mention, if you want to make indicator of indicator, maybe it is not the best way to make expert advisor for this. Instead, make another version of that indicator, new custom indicator. Unfortunately I can't help here, but this is what it's normal to do in this situation
