I tried and I failed. It seems easy for other but it is not. There will always be a problem at some point.
So I guess we could say others still prefer it doing with another type rather than bots.
Manual or with orders that are being left there.
It may not be a daily profit but there is a chance for that if you are the one who is monitoring it.
It's not easy even for the people with huge capital, trading bot strategies require a nice starting capital. Other than that, I think that many bots fail to make the profit all the time, wrong set up by the handlers, or slow bot that is unable to compete with other bots and volatile market, who will know.
I like to leave my order rather than having bot to trade for me. Maybe we are old school but it's how I like to do it.
