This is part of Kyle´s hotkey script, my recommendation for you is to read this forum post
Please note that to use this script first, you must have "Double Click to Trade" turned on in Chart, (Right-Click --> Configure --> Settings --> Double-click to trade) and to enter a trade you need to double click the chart where you want to set a stop order.ipt
Also, it is better to use Kyle´s spreadsheet and generate your own scripts with your own settings.
