Fill in Forex
A clear definition of Fill, with practical context for reading markets and making better trading decisions.
Definition
Definition
A fill occurs when all or part of an order is successfully executed. An order can receive one complete fill or multiple partial fills depending on available liquidity and the order conditions.
How It Works
Electronic markets separate the price you see, the instruction you send, and the final execution you receive. Available liquidity, order type, venue rules, and market movement can all affect what happens between those steps.
Why It Matters
This vocabulary lets you read a broker or platform screen accurately. The goal at Level 2 is mechanical literacy - knowing what a displayed price, order status, or execution record means - rather than predicting the market.
Key Takeaway
A fill occurs when all or part of an order is successfully executed.
