take a trade only after good amount of homework.
good homework ensures a win-win situation
1. either the trade will go the anticipated way and you profit.
2. or, if the trade doesn't go the anticipated way despite all that good homework, it leaves you with a learning which was apparently not included in the template you used for homework. in other words, your knowledge base increases for the next homework.
never, self doubt. never doubt the accurace of the homework or that of your decision. if homework was good and things don't go accordingly, take it as an opportunity to discover something new including the revealing of a mischief.
but never kick yourself.
a trader with low self-esteem can never be confident.
kicking ourselves only weakens us psychologically and makes us vulnerable to the mind games of the operators.
