Well this is the code that fails:
I start a script that opens several charts and installs an EA by applying a template.
The EA (just as an example) sets a global variable at OnInit() and than it removes itself with the intention that OnDeinit() delets the global variable of the EA.
//Script void OnStart() { string ChartPair[5] = { "AUDUSD","USDCAD","EURCHF","EURUSD","GBPUSD" } long IDChart[5]; for(c=0;c<5;c++){ IDChart[c] = ChartOpen( ChartPair[c], PERIOD_M1 ); if ( !ChartApplyTemplate( IDChart[c], fTPL ) ) { Comment("ERROR(",_LastError,"): Can't apply Template to [",(string)c,"] ",ChartPair[c],"? Correct and Restart ",WindowExpertName()," - Installation stopped.."); return; } } } //EA: string MyGlobVar; void OnDeinit( const int reason ){ delMyGlobs(); } void delMyGlobs(){ Print("DeInit called by: ",(string)UninitializeReason()); int g = GlobalVariablesTotal(); string gN; while(g>0){g--; gN = GlobalVariableName(g); if ( MyGlobVar == gN ) { Print("GlobalVars ",gN," Delete: ", GlobalVariableDel(gN) ); } } } int OnInit(){ MyGlobVar = "myEA: "+Symbol()+" "+TimeToString(TimeCurrent(),TIME_MINUTES); GlobalVariableSet( MyGlobVar, ChartID()); ExpertRemove(); return( INIT_FAILED ); }
But no global variable is deleted - what do I do wrong or is this not jet 'implemented' ??

If my EA is stopped I want it to delete all its global variables!
If I start the debugger the glob.vars are set but nothing is deleted if I stop the debugger:
As the initial Print is not printing and nothing is deleted I must assume DeInit() is not called and is not working at least in the debugger?
Beside that another question:
Due to the function call of DeInit();
How shall I use DeInit() that the ea deletes its glob.-vars by any reason the ea stops or is removed and the OnInit()- function will be called if re-started (is there a temporary stop of an EA?)?
Second if I stop the debugger I have these two line in the expert tab:
What does this now mean after the EA in debug-mode was stopped?
