I understand why you failed to take the leap of faith.
Discipline is knowing what to do and having the courage to do it when the time comes.
As a trader, objective is to be decisive, not to get sucked in to the emotional roller coaster ride of analysis paralysis. We are not looking for sure shot winners on every trade. We know that 43% of all our trades will end in losses. we also know that the loss is always limited to a maximum of 12 points and system will give an exit before we hit the 12 points.
Only way to be successful in trading, is to take the leap of faith based on trading system whose historical performance is satisfactory.
