This is true because being greedy in attitude will sometimes missed the opportunity to gain more because we really want much higher prices even if it is already on the top peak awaited values. I think we should think wisely to make trading that will always earned with our practical mindset.
we need to be consistent with out plan.do not be greedy , because of this attitude we can lost our profit.some time we need to close our transactionn , but we dont do this.and finally price moved down.
