Matt, if I choose to hold this trade, the problem I see is that there is now no way to know when to exit, since the system itself is not in a trade, right? Or is there some way for you to do a "mock" trade in the system at this price and give a sell signal?

Thanks for any info on how to manage the trade beyond just cashing immediately back out, if it's possible. I bought for my IRA and selling immediately will mean that for the next three or four trading days I'm locked out of that money, and can't enter a trade if SPY does go long tomorrow, the next day, etc.

Thanks.
