Stop Order
Stop order - becomes a market order once a specified price is reached or penetrated.
The stop price can be any price you indicate.
A stop order can be an order to buy above or sell below the current market price.
Stop buy orders are used to limit your loss or to protect the unrealized profit on a short sale.
Sell stop orders protect a gain (unrealized) or to limit the loss on a holding.
Stop orders become market orders so they may not get executed at that exact price.
