Execution Speed

Brokers & Regulation

The time between submitting an order and it being filled — faster execution means less exposure to slippage.

Execution speed is the time it takes from submitting an order to it being confirmed as filled, usually measured in milliseconds. Faster execution reduces the window in which the market can move against the requested price, lowering the likelihood and size of slippage. Execution speed depends on the broker's technology, the trader's connection, and current market conditions — it tends to degrade precisely when it matters most, during high-volatility news events.
