A stop limit order is a type of order that combines a Stop Order and a Limit Order, that is, a rate is set, so that when the market reaches it, instead of generating a market order , it will automatically generate a Limit Order with a certain rate to make the exchange that creates a band that is used to mitigate the risk.
Example:
A Stop limit Order is created so that when the market reaches 9400 USDT x BTC (in this example) a limit order is automatically created to acquire the BTC at 9320 USDT
