Trading bot relies on you to run. You set it up and it operates with parameters you use in configuration. Bot only does not have emotion and it can operate 24/7 without sleep time. If you use a bad strategy to set up your bot, it will only increase your lost trades and lost money. If you use a good strategy, it can help to increase your successful trades but it won't help you to gain net profit after all.

The key to gain net profit is know when you should stop your bot. Like when you feel like the market will have a next big movement but don't know where it will go, stop your bot and wait for market confirmation to reset your bot.
