MM PainDevious is good term Xiao as I see a support of warm eastern seaboard a catalyst to drop spot and thus U in advance of report. If the pain of seeing price drop brings sellers I wil buy 1/2 prior to report Thursday AM.
Once done, I will place 2 bids at report, 3% and 6% below price you see 5 minutes prior to report.
observing how MMcleans out the stop loss on trades is a good observation. Cheers Manx
