# 6. Any constraints when submitting an order?

For <mark style="color:blue;">**LMT orders**</mark>, there is a minimum order size in notional terms. Currently it is set to be <mark style="color:red;">$50</mark>.

The calculation of order notional is driven by the price and quantity as of the submission time.&#x20;

For latest minimum order setting, you could retrieve from: <http://dboe.exchange:8686/api/query/clobSpecs>&#x20;
