In my opinion, we cannot gain experience without facing losses, obstacles and tough moments. However, it is really important to learn from your own mistakes otherwise you will repeat them. In addition to that, the more you gain experience, the less you make mistakes and face losses. And if you are beginner in trading field, you will possibly lose a money at the beginning even when you have enough knowledge. As far I am concerned it is better to start with a low capital to get away the risk of loss and once you gain experience you can add or boost your capital.
The truth is that we can not run from loses totally, lose will always take place and whenever it occurs it happens be situation we need to learn from for not to repeat itself again. As far as trading is concern lose will definitely occur and it is important to know what is the cause of any lose that occurs because it should be something we need to learn from to avoid it for the future.
