I couldn't believe my eyes either. But if I told YOU what I know now you would 100% believe me that the flashcrash was predictable (and thus preventable by the FED). I have 100% proof. Too bad I learned not to give away edges. The edges does have a weakness though. The FED can ocassionally stop crashes from happening, like they did in 2010 with QE2. Maybe that was a fluke. But they didnt stop the flash crash from happening, so they probably havent discovered this edge yet. FYI, in januari of 2013 this edge predicted no crash would happen in whole of 2013.
you just had a good day, or a good week, or a good month, or a good year. If you keep doing what you have been doing you are going to lose your ass like you always do.
+1 The same for the other guy who stated the same as the OP. As long as you don't give more info or evidence of your system, it is just posturing at best....
