MT5 Error 4756 + Retcode 10019: Not Enough Money to Place the Order
If you see MT5 error 4756 together with retcode 10019, the problem is usually simple: there is not enough money in the account to complete the request. In MQL5, 10019 means TRADE_RETCODE_NO_MONEY.
This often confuses traders because the order itself may look valid. The symbol is correct, the market is open, and the lot size may seem reasonable. But the broker still rejects the request because the required margin is higher than the account can support.
That is why 4756 is only the outer error code. The real reason is in the retcode. In this case, the platform is not broken and the strategy is not necessarily wrong — the trade request is simply too large for the available funds.
If the system shows only “error 4756,” the user starts guessing. If it shows the real rejection reason, the issue becomes obvious much faster.
