6. Any constraints when submitting an order?

For LMT orders, there is a minimum order size in notional terms. Currently it is set to be $50.

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

For latest minimum order setting, you could retrieve from: http://dboe.exchange:8686/api/query/clobSpecs
