With a forex robot in scalping mode, the trades only last for a short time so it would be possible to have the robot live only when present and actually on the computer. You can simply wait for the robot to close a trade, and then shut down your PC afterward. Of course by using this method, you will miss some trading opportunities, but you also avoid losing trades in which your Internet connection dropped. Forex brokers are not thrilled about scalping or the use of forex robots, so finding one that allows you to use both can be challenging. Brokers may not be putting your trade into the forex market but matching it themselves. In this situation they don’t really want you creating regular profits at all. It’s to your benefit to avoid this kind of broker if you plan on being a profitable forex trader.
