3:50pm: Nothing has changed this afternoon. A close above 137 generates a short signal, otherwise the system remains sidelined. I've got a post planned for the weekend which will detail a strategy change in March. I'll send out a tweet when complete. Have a good one!
The system will try to short again if SPY closes above 137.00.
I just took a small short position this morning as I believe this early strength will not last. This is not a system trade, just a hunch. More later... Happy trading.
