you're right! i just use the date earlier and is resolved... must be due to position of candle to detect the crosses... eg: usually i use the date from 2010/01/01 to start and this might have caused the divide zero, and once i enter the start date to 2009/12/30 and the EA runs normally.. thanks miro for the clue!

you could check if you used crosses above/below in the condition and not = above/below

The first file you uploaded should be named CC.mq4, because it is used from the second file (CC-value.mq4). But I'm not sure that CC-value wants to connect with that particular CC indicator. CC has many input parameters:
0_1552929875728_c9ea781b-fced-471b-94a3-5057b45d1039-image.png
And when CC-value uses iCustom to load CC data, it uses only 1:
0_1552930003432_4c68ada0-7607-4a93-8bb4-32a9cbdaf377-image.png

CC works by itself, but something is wrong in CC-value. CC-value is also set to work on the main chart, but it uses values from CC that are like 0.001 and I don't see how such values can be visible on the main chart.

Great! I think this will work. Thank you very much.

So, when .mq4 file is compiled and there are error, a log file is created. Fxdreema tries to compile it, then looks for such file and if it exists it tries to extract information from it. This particular error appears when no information can be extracted, it's just a general message that says that there is a problem. But the log file is deleted immediately, so it will not be easy to see what's inside. But if you export .mq4 file and try to compile it in MetaEditor, it will probably show the problem.

This is almost impossible in my opinion. I actually can translate some parts of the website, but even if I can technically translate everything, Chinese is too far away from me and I don't have communication with any Chinese person 🙂

@fxdreema no, saved a project with another name and loaded, I have done many other times
anyway now it works, thank you

I created a new project from scratch and it works fine. Apparently there was some cache, as you suggested. Additionally I am using a different lapto with more RAM and I can confirm the error is no more. Once again the more RAM the better.
