Market orders
Fill immediately at the best available prices. Price can move while the order fills, so the fill can differ from the quote. Use one when getting in or out now matters more than the exact price.Limit orders
A limit order fills only at your price or better, and waits until it can. If your price is already across the spread, it fills straight away and pays the taker fee. Otherwise it waits, triggers when mark price reaches your limit price, and fills at the average price in the order book at your price or better. A limit order can fill partially. While it rests, the Orders tab shows its size and value, limit price, filled percentage, time submitted, and any attached TP and SL.Market vs. limit
SOL at $160: a buy limit at $158 rests until mark price reaches $158. A market buy fills at $160 and the next levels up.
Managing an open limit order
Open limit orders are in Orders. Cancel or watch the fill from there; attached TP/SL orders are listed under it. Stop and take-profit orders are trigger orders: they become market orders when price reaches the trigger.Slippage
Slippage is the difference between the expected price of an order and its average fill price. A market order fills only against resting orders on the other side of the book; when the best price has less size than the order, the rest fills at the next price levels. Larger orders, thinner books, and fast markets increase it.Example
