Please refer to the annoucement:
https://announcements.bybit.com/en/article/updates-on-tick-size-for-spot-pairs--bltb682a566a7307315/?category=maintenance_updates
📢 Notice of Error Code Update
Please be informed of an upcoming change on June 17, 2025 (Greyscale testing) and June 24, 2025 (Live) in our spot trading system logic:
We will adjust the order verification logic for spot trading as follows:
The system will only verify the minimum order value, and will no longer verify the minimum order quantity.
As a result, the error code 170136 ("Order quantity lower than the minimum") will be replaced with error code 170140 ("Order value exceeded lower limit").
This means that for all trading scenarios, regardless of change in market price or limit buys and sells, the error code 170136 will be replaced with error code 170140. Please note on this change to avoid any technical issues, thank you for your understanding.
📢 Bybit Update: Removal of Minimum Order Quantity Limit for Spot and Margin Pairs
