3:55pm: With a new SPY low, calculations have changed. We'd have to finish above SPY 136.36 to get a buy signal. I'm predicting a hold.
3:40pm: Buy signal has vanished and we are now getting a hold signal. Keep an eye on the values below to see if SPY can get back up (or down) to buy territory before the close.
1:20pm: As of early this afternoon, I'm getting a buy signal. After running all the calculations, the buy signal will be confirmed if SPY closes between 136.16 to 136.75.... or if SPY closes below 135.45. Anything else will result in a hold signal.
