A stop-limit order will be executed at a specified (or potentially better) price, after a given stop price has been reached. Once the stop price is reached, the stop-limit order becomes a limit order to buy or sell at the limit price or better.
Explanation of SL (stop-limit) mechanics:
Stop price: When the current asset price reaches the given stop price, the stop-limit order is executed to buy or sell the asset at the given limit price or better.
Limit price: The selected (or potentially better) price that the stop-limit order is executed at.
Quantity: The quantity of assets to buy or sell in the stop-limit order.
