If you really do want to do the intra-market analysis very closely the next few days, set up all your relatives like this so you dont have to do it all mentally on the fly intraday. 

Based on decades of observing retail, professional and institutional traders, that type of hypothetical approach is relatively pointless at these times. Unless you are running enormous amounts of money and trying stay relatively market neutral while capturing alpha (in which case you have quant programs making those decisions for you) no one makes consistent money trading that way at this point in a cycle. 

Instead,  the most successful traders simply trade what they see on shorter time frames  when they actually see it and then execute in whichever product they are seeing it in.

For example, if we gap up in the morning, look to see where the relative strength is. If it is the NDX, and especially the SMHs, that would favor the long side of everything. Then, if you are not already long, take the break of the first 15 min range looking for a trend day higher if it is to the upside or at a minimum a gap fill if it is to the downside (though I would probably look for a filling of the Feb 2nd gap as well).

Now is not the time so try to make decision based on intra/inter-market analysis. By definition, we are at point of a potential trend change, so until we get some resolution there is really nothing to analyze on time frames beyond a few hours.
