Regarding the SPY Systems, first off one of the newer sub systems I made, called the QE MOMO is going to trigger today most likely. Now this sub system is a tough one. First off it has a very high profit factor of over 400, which is very high. Basically what it does is like the Stochastic momentum condition I discuss all the time when a 60 length Stochastic is above 80% and faster indicators become oversold. For this sub system I require the 60 Stochastic be above 87% Here's the stats, see the first few images, I also included the trade history list.  

The only danger the sub system has of course is if the market took a hard dump, you have a high entry.  Otherwise historically the stats are good. Max draw down is 330 on 10,000 for the 1st entry that's 3.3%, and 120 for the 2nd entry or 1.2%.  One could use that for stop outs or the 60 Stochastic going below 80% anyway guys I"m trying to give you all the information I can so you can make an informed decision.  The stats are very good basically but there is some risk, though historically draw down has been pretty small. 

So it's up to you if you wish to follow the trade or not. Also the Trend/Pullback sub system may take a trade here at any time so even if you were to skip this one, probably other systems will be takign trades.
