When using a Stop order (STP), you only designate one price: your Stop Price. Once your Stop Price is hit, it will trigger a market order for execution. When using a Stop Limit order (STP LMT), you must designate two prices: a Stop Price and a Limit Price. Once your Stop Price is hit, it will trigger a limit order at the price you designated for execution.
