<p>Fill Or Kill (FOK) is an order type used in trading, particularly in Forex and CFD markets, where a trade is either executed in full or not at all. It's a straightforward concept that ensures traders get exactly what they want or nothing at all.</p>

<h2>How It Works</h2>
<p>In a FOK order, the trader specifies the quantity they want to trade and the price. The order is sent to the market with the condition that it must be filled entirely at the specified price. If the entire quantity cannot be filled at the specified price, the order is cancelled, or "killed". Here's a simple breakdown:</p>
<ul>
  <li><strong>Order Details</strong>: Quantity and price are specified.</li>
  <li><strong>Market Condition</strong>: The order is sent to the market.</li>
  <li><strong>Fill or Kill</strong>: If the entire quantity is filled at the specified price, the trade is executed. If not, the order is cancelled.</li>
</ul>

<h2>Why It Matters for Traders</h2>
<p>FOK orders are useful in several scenarios:</p>
<ul>
  <li><strong>Large Orders</strong>: Traders dealing in large volumes can use FOK orders to ensure their entire position is filled at once, preventing slippage and partial fills.</li>
  <li><strong>Market Volatility</strong>: In volatile markets, FOK orders help traders avoid taking partial positions at different prices.</li>
  <li><strong>Risk Management</strong>: By ensuring a trade is filled in full or not at all, FOK orders help traders manage their risk more effectively.</li>
</ul>

<h2>Example</h2>
<p>Let's say a trader wants to buy 100,000 units of EUR/USD at a price of 1.20000. Using MetaTrader 5 on STB Provider's platform, the trader sets a FOK order for 100,000 units at 1.20000. If the market can fill the entire order at that price, the trade is executed. If not, the order is cancelled, and the trader doesn't enter the market at that time.</p>
