Definition
Definition
An application programming interface (API) is a defined way for software systems to communicate and exchange instructions or data. In trading, APIs can be used to request prices, retrieve account information, or submit orders when the broker or venue permits it.
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
An application programming interface (API) is a defined way for software systems to communicate and exchange instructions or data.
