For anyone who thinks those "signal" trades are no
Post# of 72440
I once knew a trader who was able to identify such signals. At one point, he noticed that when the SPX moved down exactly 9.11, it then reversed up. He pointed this out consistently and it worked for a surprisingly long time. When it stopped working, he noticed another number that seemed to have the magic power (I can't remember what it was now). I witnessed this happening too many times for it to be coincidence.
