Order Placement Limits

Starting December 11th, 2017 at 12:00 UTC, the following limits will be applied:

(1) Maximum 200 open orders per contract per account;
(2) Maximum 10 stop orders per contract per account;
(3) Maximum 10 contingent orders per contract per account.

When placing a new order that causes these caps to be exceeded, it will be rejected with the message “Too many [open|stop|contingent] orders”.

These caps are designed to improve the overall trading experience on BitMEX and will be reviewed and updated periodically.
