The fix in MQL5

Work out the margin with OrderCalcMargin() and compare it with ACCOUNT_MARGIN_FREE before sending; reduce the size, or close something, when it does not fit.

Before
#include <Trade/Trade.mqh>
CTrade trade;

void OpenBuy(const double lots)
  {
   trade.Buy(lots, _Symbol);
  }
After
#include <Trade/Trade.mqh>
CTrade trade;

void OpenBuy(const double lots)
  {
   const double ask = SymbolInfoDouble(_Symbol, SYMBOL_ASK);
   double margin = 0.0;
   if(!OrderCalcMargin(ORDER_TYPE_BUY, _Symbol, lots, ask, margin))
      return;
   if(margin > AccountInfoDouble(ACCOUNT_MARGIN_FREE))
     {
      PrintFormat("%.2f lots need %.2f margin; free margin is %.2f", lots, margin, AccountInfoDouble(ACCOUNT_MARGIN_FREE));
      return;
     }
   trade.Buy(lots, _Symbol);
  }

Limits and trading risk

These tools calculate from your inputs, supported historical records or explicitly labelled teaching examples. They do not verify a live account, predict future returns or confirm that a broker or prop-firm rule has been met. Missing costs, floating losses and changed market conditions can materially change outcomes. Trading can lose the capital committed to it; check the stated method and your account specifications.
