I see that there is no complete expert trader, at a point everyone experience loss both robots. That's means the market is kind of seasonal, it can favor you today and hit you tomorrow.
Even if we think that we already know how to trade but the fact that market is unpredictable then those losses is quite normal especially when you are of control in your trades. Learn from those past mistakes and see how those seasons goes then set some trading plan so that you can develop good trades which is more beneficial for you in the long term.
Everyone can experience loss even those experience person but they can manage their trades and have set up game plan in terms of cutting there losses then set up another entry for possible reversal of their trades.
