I think if we really can use robots well, obviously, and we also really understand the robot working system, it will make it easier to trade our way, and we will still be able to gain more profit by trading using robots. but to decide to use a robot, must really learn the first robot well. and I do not believe in currency-related spiders either. This does not work well all the periods. I think the handling guide is 100% better than using software because spiders do a pre-determined treatment that does not allow effective results every time.
