I am getting frustated with this new version of MT5.
My problem: I have an indicator that when it is plugged on chart it works properly but when I try use it on my EA, it doesnt works.
My way to use that:
int trendHandle = iCustom(Symbol(),PERIOD_M15, "den_indi.ex5"); double trendValueBuy;
CopyBuffer(trendHandle, 2, 3, 1, trendValueBuy);
Well, whem I am debugging this, I can get the results without troubles.. but, the problem is when I am running backtest. My error is:
2010.09.15 23:03:28 Core 1 2010.01.04 19:00:00 Expert removed because indicator 43 cannot load 
The Indicator is in the right folder.. I am calling with the right name... well.. it is working properly in debug mode, but not in backtest mode.
Hi Stringo and Rosh,
I tried recompile and again, no results. On backtest, always I get errors, but, I don't get these errors when I am on debug mode..
It is very strange.
Can I send the EA with the indi to the championship?
I can not run backtest, but I can run live...
I am facing the same Issue
indicator 43 cannot load 
I am facing the exact same issue,
Ea and CI worked fine in build 362
problem started after install build 368
I have recompiled both EA and CI
runs fine in debug and runs fine in live
but in backtest Journal says
"loading of subfolder\CI-Name failed"
" Expert removed because indicator 43 cannot load  "
I have both my Ea and my CI In SubFolders inside default folders, I don't know if something changed related with subfolders.
I´m using the new build 373 (27 Dec 2010) and I'm having the same problem: in backtest mode, my custom indicator cannot be created (error 4802), but in live and debug mode the EA works.
Please make sure that all your sources have been recompiled successfully and you have not forgot to specify property tester_indicator.
If problem still exists please write to servicedesk.
