Haven't tried this particular bot, but I’ve used other bots that do the whole “recovery trade” thing. The idea is that they throw in extra trades when one starts to lose, hoping to get back to even or make a bit of profit.
If you're looking into automated trading, I’d say check out forexflexea.com. It works a bit differently by setting up “virtual trades” to watch the market and wait for a good moment to jump in, which feels a lot safer.
