Dear Users,
Due to market fluctuations, Phemex will adjust the Step Size for BTCUSDT and BTCUSDC perpetual futures in Bot Trading from 0.0001 BTC to 0.001 BTC, effective at 08:00 UTC on December 25, 2025.
-
After the adjustment, if your bot's order quantity fails to meet the new Step Size requirement, the bot will be automatically paused.
-
If you DO NOT manually shut down impacted bots before 08:00 UTC on December 25, 2025, the platform will uniformly deactivate them upon the adjustment taking effect.
-
Once deactivated by the platform, the bot will stop all trading operations immediately and will not resume automatic operation. You will need to adjust the order quantity in line with the new Step Size and then manually restart the bot if needed.
Please make the necessary adjustments in a timely manner to avoid any impact on your trading activities.
Thank you for your support and understanding.
The Phemex Team
