I don't know why, when we are willing to accept the defeat we experience, we become calm, allowing the defeat to happen to us, it will make us feel comfortable and we are willing to trade again, but when we are emotional, when we are not willing to lose money, we will always be filled with a sense of revenge. Our revenge will always feel insincere, high emotions that cause us to not be able to move on and this is what makes our psychology destroyed, therefore I agree that we must be able to learn to allow defeats that happen to us so that we know that in forex trading it is there are definitely wins and losses
