For eg one may have seen a relative or a friend losing money and thus this the fear, panic, and dread is reactivated at the time when one is undertaking the day trading and as a result one may not be able to pull the trigger due to sub conscious fear. Remember that emotional memory of fear clouds an individual judgment and as a result one may over-trade or enter in bad set ups.
