Here is a chart which shows the delta transacted today.
The top pane has the POC . The middle pane has the delta which is the net of volume traded at ask and bid prices and the lower pane has the volume transacted.
The initial part of the day had good volume, good delta once again showing that buyers are interested at 5570 levels. The delta was very negative when the market was at 5634 levels and price was not able to sustain there.
However in the afternoon session buyers came back again at the POC and the market moved higher.
