I advise you to read carefully what this function is for:
margin
[out] Variable which will be used to record the required margin if this function is executed successfully. The calculation is done as if there were no pending orders and open positions in the current account.
The value of margin depends on many factors and may change as the market environment changes.
Here's another question: how do you propose to calculate margin for pending orders, assuming that the pending order may or may not work?
And how do you propose to account for margin on pending orders, assuming that the pending order may or may not work?
Exactly. And not just any pending order. When there are open positions on the account, then we must ask ourselves: with what lot an order must be opened in order to keep the margin smaller than the Free Margin.
For this you must know not the leverage of the trading account, but precisely the current leverage of the symbol. And without real leverage it is impossible to determine the margin.
OK, theorists ...
Here's a snippet of code from a working program that's 100 years old.

if(Action=="BUY" && orBUY==0)
{
if(OrderCalcMargin(ORDER_TYPE_BUY,_Symbol,1,ASK,Mgn)==true)
{
Lot=Acc_Bal*Risk/(Mgn*lvrg);
if(Lot<minLot)Lot=0;
if(Lot>maxLot)Lot=maxLot;
Lot=NormalizeDouble(Lot,ls);
if(Lot>=minLot)
{
if(OpenPositions(_Symbol, "BUY", Lot, Magik_Number, "xxx")==-1)
{
Fun_Error(GetLastError());
return;
}
}
}
}
if(Action=="SELL" && orSELL==0)
{
if(OrderCalcMargin(ORDER_TYPE_SELL,_Symbol,1,BID,Mgn)==true)
{
Lot=Acc_Bal*Risk/(Mgn*lvrg);
if(Lot<minLot)Lot=0;
if(Lot>maxLot)Lot=maxLot;
Lot=NormalizeDouble(Lot,ls);
if(Lot>=minLot)
{
if(OpenPositions(_Symbol, "SELL", Lot, Magik_Number, "xxx")==-1)
{
Fun_Error(GetLastError());
return;
}
}
}
}
Well, you've got to, you've got to, you've got to!
I forgot already...
SAR, make a switch, handwrite a shoulder for each character and let the program know it.
Don't bother where the problem is solved in a nutshell, write the code and go over it.

Good luck to you!

An addition to the above:

Addendum to the above:

In such trading conditions, it is better to calculate all lots to the minimum leverage so as not to run into a sudden shortage of funds at the most inopportune time.
In this case 1k2

I have a minimum of 1k100
My leverage is at least 1k100 and I've never had a threat of it going down.

It's not just theory, it's practice.
You write an illiterate program and show everyone your "masterpieces" and talk nonsense.
If you have open positions, your program will not work correctly.

Listen, read it carefully.

I'll be writing you three letters in a word soon...

I advise you to calm down and be quiet, or I will write the worst reviews in discussions of your products showing all the defects of your programs and no one will buy them).

that's up to you, i'm not threatening.
I just showed you what you can not see for yourself.
that's it

I've got a minimum of 1q100, so far they haven't threatened to cut my losses.
