You can't say that you are overtrading because if you are a responsible trader, you will know how to limit your trading and limit your losses as well. But let's say if you are just starting to trade, then it's always best to learn from your own trades. Do not be afraid to commit mistakes and losses because that will be your great motivation to improve your trades and become professional and profitable traders in the future. Furthermore, know that trading signals can never be reliable the whole time. They might work at some point but you will know your trades will work better if you rely on your own knowledge and skills as a trader.
