Error number 6 - page 2

 
<br / translate="no"> there is a limit to the number of charts - 99. so there is also a limit to the number of experts


Well, no. Not my case. Firstly, I have less than 99 Expert Advisors. Secondly, I'm not planning to work for a long time - restart and alert within an hour.

So, can you take a look at the expert?
 
And hot on the heels of that. Another expert. What kind of indicator it is, doesn't matter. The important thing is that I found two trades opened by it in the same currency. The Expert Advisor logic does not allow for this. Logically (if you look at the charts), the previous trade should have closed. And it did not. There is nothing in the logs. The same symptom?

The Expert Advisor I gave above is a better idea. Everything is simpler there in terms of code. And there are no indicators.

I have had 9 EAs in one account for 2 months now. I have implemented such a construction in all of them:
ticket=OrderSend(Symbol(),OP_SELL,Lots,Bid,Slippage,Bid+StopLoss*Point,Bid-TakeProfit*Point, "sell",ExpertMagicNumber,0,Red); if(ticket<0) { Print("OrderSend failed with error #",GetLastError()); return(0); }



Logs are clean, orders are placed.

What can I say? Try my Expert Advisor, the one I cited first. It gives one trade per hour. Usually the second trade leads to an error message. If there is no error in 24 hours, I don't even know...
 
Hung up, should do something in 10 minutes apparently. I hope he doesn't break my other EAs. Yo000, he has already opened an order, you promised every hour and it hasn't been a minute.

The first time it opens an order at once (see check for conditions at the beginning of a bar). Then, if you don't touch it, at the beginning of the next hour.
 
Well, the circus continues. Hung up Alert on the second expert. At the beginning of the hour two curves were expected to cross and he honestly tried to open an order. Instead it got error number 6. Gentlemen developers?
 
Rosh, listen, thanks for your help, of course. But I was wondering, my EA tracks "its" trades by magic number. If your approach is the same (each EA has its own opinion), then I'd like to make sure that it does not close other people's orders. If your approach is the same (each EA has its own mn), then you have to make sure that this EA's mn does not overlap with yours.
 
I'm writing floods because reading these kinds of posts makes me very sad and need to say something, especially since I've already had a couple of drinks...

Very much I hope that Quark in his expert screwed up. Can't check it myself yet, writing from a PDA away from the computer. But if it's MT, then f..., however, hussars silence!
 
Truly silent :)
