I have a similar problem. ChartSymbol() returns an empty string.

string chartSymbol=ChartSymbol(chartid);

It has been working until the last update. Actually it is still working on my development windows pc, but not anymore on my vps on which I run MT5 under linux with wine.

I have two  MT5 build 4231 installed on two difference computer,    one is error as above(C:\Program Files\MetaTrader 5), the other is OK  (d:\Users\RW\AppData\Roaming\MetaQuotes\Terminal\D0E8209F77C8CF37AD8BF550E51FF075).  does it cause by the difference of data folder?

Inserting delay <for example 1000-2000 milliseconds> inside this hard loop has a chance that then everything will be fine

I have downgraded the teminal to the build 4153 and now my EAs are working. Hope this will be fixed soon.

I would like to know where can download build 4153,    does it auto upgrade to build 4231 again?
