Starting 04:00 UTC on 05 June 2020, the threshold used to detect spam orders will be increased from 0.0025 XBT to 0.01 XBT. For more details on the spam mechanism please see our REST API docs on Minimum Order Size. After this change accounts with too many open orders with a value less than 0.01 XBT each will be labeled as a Spam Account (prior to the change, the value is 0.0025 XBT).
This change is part of an ongoing effort to improve the quality of the tradable liquidity on the platform. If you have any further questions, please contact Support.
