What it means
You see this code in the retcode of a trade result, from OrderSend() in MQL5 or order_send() in Python.
Brokers can cap the number of pending orders an account holds at one time. At the cap, a new pending order is refused with 10033.
The cap is visible in the account information, so you can check it in advance.
Common causes
- Grid strategies that leave many orders open.
- Old orders that were never canceled.
- Several programs placing orders on one account.
How to fix it
- Compare
orders_total()withaccount_info().limit_ordersbefore placing. - Delete orders that are no longer needed.
- Use expirations so orders clean themselves up.
Example in Python:
import MetaTrader5 as mt5
cap = mt5.account_info().limit_orders # 0 means no cap
if cap and mt5.orders_total() >= cap:
print("at the pending order limit:", cap)Is it safe to retry?
After you remove some pending orders.
Could the order have executed?
No new order was placed.
