Getting Returnes from .ex4 files

Hi there still kind of new to all of this , was just hoping if anyone can tell me if it is possible if you could get returns and values from .ex4 files that you don't have the source code for.

E.g writing a custom EA to read the take profit displayed on the trading screen from some indicator that has already been compiled and I don't have the source code.

hope my explanation is sufficient.

Thanks a lot !

That depends on the kind of .ex4 file. If it is an indicator, the answer is probably. If it is a Script or Expert Advisor .ex4 file, the answer is no. I think from your posting, you are referring to an indicator and I will explain how to obtain values from the file.

I assume that you have decent programming skills and will understand documentation and programming examples. The function to do this in an EA is called iCustom and it is well documented here. http://docs.mql4.com/indicators/iCustom

All that is left is to figure out which indicator buffers contain the values that you are after. Its just a matter of trying buffers 0 to 7 and making sure the values in the EA match those on the screen. It works as long as the values are in an indicator buffer and not an object. Object values require the use of ObjectGet and I don't want to discuss that.

I recently wrote some code to accomplish this, here is a basic example, hope it helps:

Inserted Code
int trade;

trade = iCustom(NULL, 0, "INDICATORNAME",13,1,0);

if (ObjectDescription("txt2") == "Short")
     OrderSend(Symbol(), OP_SELL, 1, Bid, 25, 0, 0, 0, 0, 0, Red);

if (ObjectDescription("txt2") == "Long")
     OrderSend(Symbol(), OP_BUY, 1, Ask, 25, 0, 0, 0, 0, 0, Green);
The onscreen text is stored in the "Description" field (at least for the indicator I was using here).

Good luck!

yes it is an indicator not an expert advisor...

Thanks for the help!
