The 25 Point Discipline For Day Trader - #5 And #6

I continue my post about The 25 Point Discipline For Day Trader. And below is the 5th and 6th point
 
#5 YOUR BIGGEST LOSER CAN’T EXCEED YOUR BIGGEST WINNER.
Keep a trade log of all your trades throughout the session. If, for example, you know that, so far, your biggest winner on the day is five e-Mini S&P points, then do not allow a losing trade to exceed those five points. If you do allow a loss to exceed your biggest gain then, effectively, what you have when you net out the biggest winner and biggest loss is a net loss on the two trades. Not good.
#6 DEVELOP A METHODOLOGY AND STICK WITH IT. DON’T CHANGE METHODOLOGIES FROM DAY TO DAY.
I require my "students" to actually write down the specific market prerequisites (setups) that must take place in order for them to make a trade. I don't necessarily care what the methodology is, but I do want them to make sure that they have a set of rules, market setups or price action that must appear in order for them to take the trade. You must have a game plan.
If you have a proven methodology but it doesn't seem to be working in a given trading session, don't go home that night and try to devise another one. If your methodology works more than one-half of the trading sessions, then stick with it.
