Anyway, people here have different opinions base on their experience and base on the feedback they've from other users.

Using bots in trading still lying on your strategy, it works according to your command. If you fail, then literally, the bot will also fail resulting in a loss.

The truth about trading is that you can never rely on everything in them but still for you to work. If you are already comfortable in manual trading and you are already gaining, much better to stick there. I'm prepared to do manual trading than using the bot.
