# Create Order

> For limit orders, create an order for buying or selling an asset:

- To buy, set `side = BUY` and set `base_amount` to the crypto amount you want to buy.
- To sell, set `side = SELL` and set `base_amount` to the crypto amount you want to sell.

For market orders, create an order for buying or selling an asset:

- To buy, set `side = BUY` and set `quote_amount` to the dollar amount you want to spend.
- To sell, set `side = SELL` and set `base_amount` to the crypto amount you want to sell.

There are five types of orders:

- Limit Orders: Buy or sell at a specified price or better. Execution not guaranteed. Taker orders will be rejected if price deviates 15% from midpoint.
- Post-Only Limit Orders: have the same properties as Limit Orders, but get rejected if they cross the orderbook.
- Market Orders: Operate as Immediate or Cancel (IOC) orders. Price is variable, executes at best available price at time of order.
- Stop Market Orders: Will convert to a market sell order with the specified quantity when the stop price is hit. The stop price does not guarantee that it will be executed at that price. Market conditions (price) might change between the order being triggered and order being executed. Currently only sell stop loss orders are supported.
- Stop Limit Orders: have a Stop Price which when hit, will convert to a limit sell order that will be executed at a specified price (or better)
