As a reminder - yesterday I posted on the Trading Community that the SPY system would be exiting its long position on the open - you can see from the image below.
That said - one option in case you didn't exit yet, if you thought the market could push higher - simply stay long with a stop at today's open -that way if the market rallies from here you catch it, but if price turns down you have a stop basically at the exit price of the system. Otherwise I'll count the trade as closed officially on the website
