What's wrong with that? - page 3

Please tell me why this script does not open deals and shows error 0, i.e. no error, but does not open deals.

I think your stoploss is bigger than the opening price

[asasusa]

Right, and there's no error.

[asasusa]

Tell me how to decipher this, I don't understand how this piece works

    for(int cnt=0;cnt<OrdersTotal();cnt++)
     {
      OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);

So first we set the cnt variable to 0

Then, if the number of orders exceeds 0, OrderSelect is triggered.

But what is this same variable cnt with value 0 responsible for?

 OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);

Try just reading about the function and it will be clear in no time.

[asasusa]

No nothing has become clear, why exactly 0? Are the orders numbered from zero or what?

And there is more.

OrderType()<=OP_SELL

How do I know if this is less than or equal to a sell order? Which one is smaller and which one is bigger?

yep, from scratch. just like everything else.

And there is more.

How do I know if this is less than or equal to a sell order? How do we know which one is smaller and which one is bigger?

because OP_SELL is constant=1

[asasusa]

So

OP_BUY - 0
OP_SELL - 1
OP_BUYLIMIT - 2
OP_BUYSTOP - 3
OP_SELLLIMIT - 4
OP_SELLSTOP - 5

that's how it works?

sss2019:

So

OP_BUY - 0
OP_SELL - 1
OP_BUYLIMIT - 2
OP_BUYSTOP - 3
OP_SELLLIMIT - 4
OP_SELLSTOP - 5

that's how it works?

Right. True, there is another value that equals 6.

[asasusa]

What else is it going to be?
