Many traders are obsessed with the perfect trade, perfect technical indicators. Trading is the field of non-existent "perfect" words. You can have a very detailed plan, but finally be surprised by a crazy market situation, like a cold water droplets in the face.
Instead of trying to reach the perfect trade, change yourself to the market. Average predicted of you about market, average with another trader ( why not? ). You should accept fewer profit but you will lose less. You should sell sooner and buy later than your prediction. follow the market, because the market will not follow you.
Yes you are right.Instead of trying to stick to our plan and bearing losses,its always better to be flexible and decide as per the market situations.Its better to get satisfied with a smaller profit and trades could be made further in future to increase our profit.
