Same here. Error "array out of range" referring to the following lines:

UpdateEventValues(EGV_OrderList[OrdersTotal()-1],"new","");
or
if (EGV_PositionsList0[i].type != EGV_PositionsList[i].type)
or
if ((EGV_OrderList0[i].sl != EGV_OrderList[i].sl) && (EGV_OrderList0[i].tp != EGV_OrderList[i].tp)) {

Same EA, different times. Unfortunately, this error can not be reproduced in Strategy Tester. Occures only in realtime trading (demo & real). Happens faster if more EAs are running at the same time. Found no solution so far. This stopped me from using fxDreema & EAs a long time ago.

I received critical error 502 in OnTick function when I moved a block ("Position closed") from the OnTrade area to the OnTick area. Maybe it's something like that in your similar case too?

@fxDreema
Now I come up with some new error messages: (was quite busy the last time)

It is still a big problem, that my EAs keep terminating themselves without any visible reason! Tried different ways of building my EA. Tried different MetaTraders with three different Brokers. On some the EA runs longer, on some shorter. But 75% of them die!

Do you see a solution?

The EA terminates itself right in the second, it creates a position.

Tab Journal says: "170914_OpenPosisGroupIDonlyForCheckOpen_v8 (EURUSD,M1) removed"

Tab Experts says at the same second: "array out of range in '170914_OpenPosisGroupIDonlyForCheckOpen_v8.mq5' (3605,41)

And Line 3605 is: UpdateEventValues(EGV_OrderList[OrdersTotal()-1],"new","");

It could be a good idea to prevent the EA from trading while the connection to the server is very slow, I think.
Does anyone know a way to do this? I just could find a way to ask for the name of the server ...

@miro1360 This EA is for small & easy tests.

I started 4 instances of this Test EA yesterday evening. Only 1 of them "survived" until this morning. Log just says:

From time to time the EA decides by itself to quit. It just disappears from the chart. As far as I can see, this usually happens after opening a position.
Does somebody else know this effect?

EDIT: I still didn't solve the problem! Thought so, but I have variables adding "1" every bar for each EA. So they are influencing and disturbing each other unintentionally!

I just don't get it! Why are different MagicNumbers not enough to keep all EA's actions only by themselves?!

Now it works this way:
Giving every trade from one EA the same group number (111) and every trade from another EA another group number (222) and so on. Actually, this should be the same like another MagicNumber for every EA.
But anyway, if it works, it works.

What is "Check positions/pending orders count" checking in detail?
Any position of an instrument using the same MagicNumber like the checking EA itself?
Or any position of the instrument, looking at nothing else?

I thougt, one EA would only recognize positions/orders of its own MagicNumber. So I tried to run more EA's on one instrument. But I'm not sure anymore. Somehow, the other EA's won't open any new position if another EA has opened one already. (Exception: More EA's open one position at the same time. In this case, there was "no trade" before.)

Using groups also seems not to solve the problem, because "groups" only extend the existing MagicNumber for some digits.

@fxDreema I posted this link several times:
https://fxdreema.com/shared/k7s6vOlzc
Also, I described the problem several times in this thread.
From my point of view, the problem is in the block "Indicator moves within limits". I tried to localize the source of the error as far as I could. But I can not compare the block compiled before and after the update. So you have to do it.

The EA is not clearly broken now. The results differ. Maybe, it was "more wrong" before and is "more good" now. If this is the case: Please tell me what to do, to receive the results I've had before. (If is is possible in any way.) Because this always was better. In every backtest and also in demo trading.

@miro1360 Thanks for that good idea and the link, Miro.
I really thought, I could localize the cause of the problem a little bit. But unfortunately, the desktop version doesn't work on my two computers.
Tested on Windows 10 and Windows Server 2012 R2.

Even the easiest EA containing "No Trade" and "Buy" (see picture, I didn't find "share copy" or anything like that) results in no trades at all. Same EA from online version trades.

Also, I couldn't import (error pic 1) or copy&paste (error pic 2) any EA's:

@fxDreema So there still is an action urgently required from you!!!
