Only one daily SR came into play today.  There was one potential trade setup around 12pm EST, but price would have needed to break the low of the day for an entry.  Price bounced off the LOD and moved higher again.  The day did however present three divergence trades.  Since there were no good SR targets, the trades would have needed to be managed in another fashion (such as targeting previous swing extremes and tightening your stop as price approaches them).
