Evaluation will always be very important for us to use when we lose. Why is evaluation important because with evaluation we know what went wrong and what we have to fix because it is with evaluation that we become aware that when we trade, we must be able to make a profit, not lose indeed in practice there will be a lot of losses that we get but the percentage must be smaller than the profits we get and we also have to be professional in improving or evaluating each of our performance so that later we don't get consistent defeats.
