The orders can be placed by ”order_amount” instead of “order_quantity” for MARKET, BID, and ASK orders.
If Margin trading is disabled and you want to place orders via API, please keep these rules in mind:
- The “order_amount" is not supported when placing a SELL order
- The “order_quantity” is not supported when placing a BUY order.
It's the size of the order in terms of the quote currency instead of the base currency. The order will be rejected if both order_amount and order_quantity are provided.
Note: The precision of the number should be within eight digits.
