Developers: What does this mean and why?

Sergey Tabolin:

And what should be done?

Now I have run the ExpertMAMA test from the standard advisors folder. As they say, an oil painting. It works in one terminal, but not in others.

I must say, I have all the terminals are SIM.links to all the folders of type Experts, Include, Indicators, etc.. in Other words all taken from the same place. Until recently, this method worked perfectly and there were no problems…

Sergey, well, it is clearly written

set the mathematical calculation mode or set up test dates

Apparently there is no data for testing. That is, there is no history, and the history is not in the listed folders and each broker has its own.

This is my cuckoo and it should always cuckoo where I tell it to )))

So you’ve gone wild already.

An owl is not a cuckoo. For free, it will not cook.
