Steve: i don't believe there is any possible TA that would have alerted to the MRK disaster which is causing the DOW to take a hit. you have done great thus far with your system. i would not feel so bad if i were you.
I believe DOW will recover most of the hit by close. My experience says that market movement on a single company single issue specific news is usually negated by the broader market except for that specific company. IMHO.
