Can this robot help me in trading?
It won't help you if you don't know what you're doing. Bots can automate the trades you tell it to make. If you tell it to make bad trades, it may even amplify your losses beyond what you might have lost trading manually.
So I prefer the good old way of trading manually
If you're more of a strategist you can automate your trades and that can be helpful, although your strategy needs to really be well thought out. Otherwise you're 100% correct, this can very well amplify your losses if your strategy is inherently flawed.
