AsAn:
The SymbolInfoDouble(_Symbol, SYMBOL_MARGIN_INITIAL) function returns 0 on all instruments, how and what can be fixed?

What are we trying to get?

Trying to get the amount of initial margin to open a position.

This is not an error.

SYMBOL_MARGIN_INITIAL and SYMBOL_MARGIN_MAINTENANCE are used in futures specifications and are not used in forex instruments.

Use the OrderCalcMargin function to calculate the margin.

To calculate the margin, use the OrderCalcMargin function.

It's a little different. I need to calculate lot size based on available funds and initial margin. In OrderCalcMargin I already need to specify the size of the position to be opened. In MQL4, the initial margin value was obtained using MarketInfo(Symbol(), MODE_MARGINREQUIRED), and then I performed necessary calculations.

AsAn:
That's a bit of a misnomer. I need to calculate the lot size based on available funds and initial margin. In OrderCalcMargin, I already need to specify the volume of the position to be opened. In MQL4, the initial margin value was obtained using MarketInfo(Symbol(), MODE_MARGINREQUIRED) and then I performed necessary calculations.

Calculate the margin for one lot, then divide the amount of free funds by the obtained value - this will be the number of lots in the first approximation. Then round up to the lower side taking into account the minimum volume change SYMBOL_VOLUME_STEP and you can load the account to the full extent.

When will the changes to the 305 build be published?

[Валерий]

1. Tester: The drawing of the test results graph has been optimised.

It would have been better if it had not been changed.

[Jmiller]

Dear developers!

When can we expect visualisation of testing in the Tester?

At least tell me a month?

Definitely after the Championship, though it may be two weeks before it... :)

int test()
{
while(true)
{
return 1;
break;
}

return 0;
}

Why does it return "0"? If you use for instead of while, it returns 1.

Another question

string  PositionGetSymbol(
   int  index      // номер в списке позиций
   );

"number in the item list" what is this number?
