Updates on Minimum Order Size for Spot and Margin Trading Pairs
Minimum Order Value vs Minimum Order Quantity
Some exchanges are moving away from enforcing a minimum quantity (e.g. 0.0001 BTC) and instead enforce a minimum notional value (e.g. $5). This gives more flexibility, especially in volatile markets or for low-price assets.
-
Tick Size / Price Increment Adjustments
Even if quantity rules don’t change, the price increment (tick size) might. That means prices must be in increments of e.g. 0.01 rather than 0.001, which can affect how precisely you can place limit orders. OKX’s change is a good example.
-
Decimal Precision for Quantity
Some platforms refine how many decimal places you can trade. Pionex increased the required precision (i.e. more decimal places) for certain pairs.
-
API vs GUI Differences
Changes often apply differently to API vs web/mobile UI orders (e.g. rounding rules, minimums). OKX states that orders using old precision will be rounded (buy orders rounded down, sell orders rounded up) for API users.
-
Impact on Order Types / Bots
Open orders with greater decimal precision than the new tick size may be canceled, bots may stop and resume, etc. OKX gives that as a scenario to plan for.
