Coming back to scalping, it's good no doubt but you must either use bots or have a team under you who do all the manual work while you can just guide them through it. It's a headache trading all day and earning few dollars after burning your eyes in front of the computer all day. Mind you, I was someone who has done scalping in past and I wasn't even aware of this word and used to call it price-trading until recently.
In my opinion, the best bot is the one you wrote yourself. But this is not available to everyone. All purchased bots of third-party campaigns ... well, I don't know, I don't trust them (maybe I'm just paranoid) In general, if you can afford a command that will perform some actions for you, then this is more like a hedge a fund where professional traders trade for you. But they are unlikely to be involved in micro-scalping. I think that with the money for which they enter positions, we are talking about at least medium-term trading.
