Friday is the day where most of these things happen :
You lose your weekly gains
You over trade to make back your loses
You over risk to make back your losses
Treat Friday as a day to go over how your week went. Be VERY selective of the trades you take on Fridays !
How long will you lose all your profits on Fridays ? For how long ? Lower your risk on Fridays.
