Setting a FOK (fill or kill) order implies that the entire quantity of an order must be executed immediately or be canceled in case it cannot be executed at the specified conditions.

By setting a FOK order you can ensure that the order is executed entirely at the set price range or not at all.

FOK orders are very useful when volatility is high. By placing such an order, you can protect yourself from sudden drops or increases.

What is Slippage?

Slippage-ul is the difference in price that can occur between the placement of a trade order and its actual execution. There can be a very small amount of time between the moment an order is placed on a platform and when it is executed in the market, during which rate can move. This movement in prices between the requested rate and the obtained rate is called Slippage.

For FOK orders, you can specify the acceptable Slippage for executing an order.

For example, assume you want to execute a buy order for BTC at a price of 46703.11 EURO with a splippage of 10 bps (1 bps = 0.01%). The order will only be executed if the price movement is within the range of 46656.41 EURO and 46749.81 EURO, otherwise the order will be rejected.

How do I add a Fill or Kill (FOK) order ?

From the trading page, click on Buy or Sell.

From the next list, select the Fill or Kill:

Enter the amount, slippage and click on the Add order button

All that's left is to confirm the order in the next step.

If the market movement is within the range you selected, this order will be executed, otherwise, if the movement is greater in the market, the order will be rejected.
