can place multiple sale orders for a stock
When you place a limit order to buy, the stock is eligible to be purchased at or below your limit price, but never above it. When you place a limit order to sell, the stock is eligible to be sold at or above your limit price, but never below it.Although a limit order enables you to specify a price limit, it does not guarantee that your order will be executed. stop limit order to sell becomes a limit order, and a stop loss order to sell becomes a market order, when the stock is bid (National Best Bid quotation) at or lower than the specified stop price.
