Order types: market, limit, and stop
Order Types: Market, Limit, Stop
TradingDefinition
A Market order fills immediately at the next available price. A Limit order fills only at the price you set or better, so it may not fill at all. A Stop order becomes a Market order when the price touches the level you set, which is how a stop loss is placed.
Detailed explanation
The choice between types is a choice between price certainty and execution certainty. A limit order gives an exact price without slippage, but the market can run away without you. Market and stop orders guarantee an exit, but in sharp movements or during news, the fill can be far from the price you saw. In a prop account, there's another consideration: even a pending order that wasn't filled can violate a rule. In some firms, pending orders must be canceled before the daily close or before news releases.
An example from the prop world
ES trades at 6,000. A buy limit at 5,995 will only fill if the price drops there. A sell stop at 5,990 on a long position will exit you when the price reaches that level, even if the actual fill is 5,989.75.
