no it won't work. When the stop is triggered, the system will try to create a sell order, but this order will fail because the number of shares you are trying to sell exceeds the number you have available (because there is already a sell order for the same shares in the market at your exit target). You can't place multiple sell orders for the same shares at the same time. What you can do is place multiple stop orders - the first one to trigger will place the sell in the market, the others will fail if they are hit. So set up a stop order to sell at a specific price (for your target trade), and set up a second stop on a percentage move (your safety stop). Also, use percentages for number of shares/warrants to trade rather than an absolute number. Use 100% to sell all that you have available. But make sure you don't place any actual sell orders, or the stops will fail to execute properly when they are hit.
