Just a suggestion. It was not at all cowardly to stand aside today. You might consider developing some measure of wide- versus narrow-range days.
All, a good trade would have also have been to enter long at 8180 inital stop at 8130 /w 50 points risk (my stop was too tight) take profit at 8210 for 30 points profit or fade all 30 point moves (with 30 points target) today or stay aside ;-) It was fun today! Thank you!
