Trading bots have always sounded like a good idea especially for people that don't know much about trading or want decent profit. Even though it sounds like a good idea, I rarely see people use it much or hype it up especially the good traders.
Trading bots are not great in my opinion due to the automation that they are, there are decisions that a human will make during trading just because of the intellectual capabilities this is something that bots cannot handle. You point it out that it is for people that don’t know how to trade and I say if anyone doesn’t know how to trade then they shouldn’t be trading nothing like using a Bot, there are many things one need to know even if they want to use the bot things like risk management, so if the person doesn’t know how to trade they will simply Just end up losing their money with the bot. The best strategy in trading uptill now is your own strategy.
If you have a good knowledge of TA and the modifications is right. They can be great.
