A professional trader is not exempted from losses, they run at loss too. If you are making more profit than losses win trading, it means that trading is good for you and you should continue, but if you are running at loss more than profit, it is better that you stop trading. Trading is not by force but it should be that you are passionate about it, and have your own strategy that you can come up with to help you be profitable when trading.
At the beginning of my trading I also often experienced losses and I did not give up and learned to change strategies, deepening the analysis because becoming a trader who can get higher profits than losses is not easy and requires experience. Currently I always practice by analyzing every mistake I make with focus, finally now I can get profit in every trade I make. because risk management is also needed in trading.
However, every trader knows that he is going to loss sometime and it is very normal. When we are able to make more revenues than the expenses incurred during the operation, then we realize that we are on the right path, and have the right plan. In trading we cannot afford to remain static because the situation keep changing in the market place. If we can identify a pattern that yield positive result, it makes sense to keep on with and optimize the approach.
If we subject ourselves to more losses than profits, this is an indication that we may require a change of strategy. It should not be a business of forcing or pushing but doing what you love with a good plan. We have to develop something like our own favorite strategy that is more tailored to our personalities, where things like organization and contingency assessment always form a part of the equation. Having learned how to identify the right level of risk and potential profit we would be able to move forward to further becoming master traders.
