Stop order
An order that becomes a market order once price crosses a trigger level. Used for breakouts and stop losses.
Stop buy above current price fires on a breakout. Stop sell below fires on a breakdown. When triggered, it fills at market so slippage applies. Don't confuse with limit orders - stops chase momentum, limits wait for pullbacks.
