S&P 500 Price/Volume Heat Map- 7/30 Trading Day Edition

The market was little changed in yesterday's trading. This is as losses in the consumer sectors, energy, and to a lesser extend materials and telecom was largely offset by gains in tech and industrials. 

I see the price/volume heat map indicating a far less sanguine supply/demand balance. This follows a price/volume heat map that has indicating weakening demand and/or increasing supply for a few days now. Technology shares were the standout, but the remaining groups experienced a mixture of flat to negative supply/demand characteristics.
