Quote from tradingjournals:
SPY @ 179. A model that estimates sellers and buyers says that market is sitting at around mid point with 0.33 up and 0.37 down for where buyers and sellers would be according to model.
A test for this model is to journal a short of 1/8 size.
SPY at 178.89 (earlier, in AH 178.87). Model signal to close. +0.11. RR=13/25 ~ 0.5.
