MetaTrader error codes / MT4 trade server errors

MT4 error 147: Expirations are denied by broker (ERR_TRADE_EXPIRATION_DENIED)

The broker doesn't allow expiry times on pending orders. Send the order with expiration 0 and cancel it yourself later.

147ERR_TRADE_EXPIRATION_DENIED
After a fixSafe to retry?
NoCould it have executed?

What it means

You see this code in GetLastError() in MQL4, after a trade function fails on the server side.

You set an expiration on a pending order and the broker doesn't accept expirations.

The order wasn't placed.

Common causes

  • A non-zero expiration argument in OrderSend() or OrderModify() at a broker that refuses it.

How to fix it

  • Pass 0 as the expiration.
  • Keep your own end time and delete the order with OrderDelete() when it passes.

Example in MQL4:

RefreshRates();
double price = NormalizeDouble(Ask - 300 * Point, Digits);
int ticket = OrderSend(Symbol(), OP_BUYLIMIT, 0.10, price, 3, 0, 0, "", 4711, 0);  // no expiry
datetime myExpiry = TimeCurrent() + 4 * 3600;   // delete it yourself after this

Is it safe to retry?

Yes, without an expiration.

Could the order have executed?

No order was placed.

How Tickwire handles it

Tickwire treats it like MT5 10022, and the MT4 code stays in the message.

On MT4 accounts, DAY and SPECIFIED_DAY expiry is refused with not_supported_on_mt4 before sending. Use a set expiry time, or none. See platforms.
