There's no such thing as a free lunch. You'll make peanuts from bots compared to actually learning how to trade
the only way to trade profitability is to leaned how trading work and develop your trading skills and strategies. I have tried to used bot when I was trading forex but it doesn't work for me so I have to abandoned it and focus on my skills and manual trading.
I believe your experience must be the most common for most of the traders, because I guess we need quantum computing in order to create one versatile trading bots as the possibilities and variations of trading are unlimited so few set of coding sequences will never able able to cover all those various market conditions.
Manual trading has some minimum guarantee to withstand any market condition whereas trading bots are highly known for fetching losses in typical market conditions like highly volatile price movements.
