Impact analysis
The confirmed operational change is confined to price granularity on one pair: the smallest permitted price step for CPUSDT Futures is now one-tenth of its previous value. MEXC explicitly states that trading and related functions are not impacted and that pre-existing orders remain valid and are matched at the original tick size, so the change applies to order placement going forward rather than to the existing order book. The only direct action the source ties to the change is for API and strategy users, who are told to align with the new setting and can query current parameters through the stated endpoint. The announcement does not describe effects on spreads, depth, leverage, margins, or any other pair.
What the announcement does not say
The source does not quantify the liquidity improvement it cites as the rationale, does not state whether the tick size could change again, and does not specify which strategy types or order types are most sensitive to the new increment. It also gives no detail on how the API response fields differ beyond pointing to the endpoint.
Risk notes
- Automated strategies with hard-coded price increments for CPUSDT may submit prices that no longer conform to the new tick size; the source flags potential disruptions but does not describe them.
- The announcement's liquidity rationale is a stated intention, not a disclosed outcome; no post-change market data is provided.
- The source does not address asset safety, custody, or account security, and nothing here should be read as confirming them.
