Each bot has a different trading strategy, so you must study it more to find one that works. But bots like that are unreliable because you still have to rearrange the orders so that they work according to market conditions.
Rearranging of orders is for someone who already have a strategy and understand the market movement but some traders especially those running after bots don't have strategy or don't trade by themselves, they only rely on application of the bot. Bots sometimes can malfunction to the extent that before you realise it all your capital is gone. I don't advise traders to only rely on robot but if you already have the trading skill , you may as well combine if you feel so . However taking a manual decision is better and including your SL.
And that is assuming the bot malfunctioned at all, as for the most past computers do what you code them to do, so if there is a mistake on the way to bot is behaving most of the time that mistake can be traced back to the programmer.
Still this idea of using bots to trade the markets and obtain a huge amount of money with no effort at all is the dream of newbies, as anyone which has traded the markets before knows that such a thing is almost impossible and they know that if they want to obtain some profits then they need to learn how to trade on their own.
