Execution speed: how fast are your fills, really?
Execution speed matters for scalpers and news traders, and the marketing numbers rarely match the experience. Members sharing measured impressions help more than any brochure.

The bid, ask and slippage guide explains the mechanics behind fills.
Background: Bid, ask and slippage: why your order fills at a different price
Why buy trades open at one price and close at another, why a stop can trigger when the chart never touched it, and how slippage happens.
Why did my stop-loss trigger when the price on the chart didn't reach it?
Charts usually show the bid price, but a sell position's stop is triggered by the ask. If the spread widened, the ask could have touched your stop while the bid line stayed away from it.
What is slippage?
The difference between the price you expected and the price your order was filled at. It is most common in fast or thin markets, such as around news releases.
