Vladimir Pastushak:

This is wrong and so are the other examples.

If you put a stop at 1.2356 and on the new tick you put a stop at 1.2356 again, you will get error 1

This is from the first block. I changed it, but the error remained. This condition with a stop has been implemented for the EA not to make unnecessary passes. And on a new tick, the EA will not set the same stop again - because after this condition I will check other conditions, for example, if the stop is equal to the value I want to set.

OrderStopLoss()

All Order...... () must be normalized

[Alexandr Sokolov]

Vladimir Pastushak:

All Order...... () needs to be normalised.

I did that - and it didn't help either. At the same time, as before I don't have this error in the tester, and MQL somehow finds it

do a one to one example from the articlehttps://www.mql5.com/ru/articles/18

the codes from the article work 100% in mt4, i checked it in January of this year

Alternatively, you have compiled a project for a 64 bit dll, MT4 terminal is 32 bit, you need to configure and compile a project for a 32 bit .dll

Hello, dear forum users.

Can you please explain in which case the code is written correctly and in which not correctly and why (see below)?

for (z=OrdersTotal()-1; z>=0; z --)
    {
      OrderSelect (z, SELECT_BY_POS);
      if (OrderSymbol()!=Symbol()) continue;
      if (OrderMagicNumber()!=MAGIC) continue;
      if(OrderType()==OP_BUY)  CloseBUY();
    }

for(int i=OrdersTotal()-1;i>=0;i--)
            {
            if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES))
            {
             if(OrderSymbol()==Symbol() && OrderMagicNumber()==magic)
             {
             if(OrderType()==OP_BUY)  CloseBUY();
             }
            }
            }

If possible, in more detail. Thank you.

Even the compiler will highlight to you in the first case"the result of OrderSelect must be checked" ;-)

If you change for the first one if (!OrderSelect(...)) continue; then the options are identical.

In the first one the code is visually linear, in the second one it looks like a staircase. I prefer the first variant, it's easier to read and in general, occurrence of deep logical tabs {{{{ }}}} hints that it's time to change something :-)
