Detailed chart analysis of past trading action
Identified where reversion and break-out trading occurred

The image below is the chart of iShares Leh 20yr Treasury Bond TLT ( ARCX Ticker Symbol: TLT ).

It is a multi-days chart showing Composite Time Price Opportunity (TPO) Profile on the left side and Composite Volume Profile on the right side.

This is an unique charting technique and requires some explanation on how to read the chart.

This chart shows more information than the conventional graphical chart.  Reading this chart will stimulate your whole brain.  The left hemisphere of your brain which is responsible for logical, rational and analytical functions will be engaged by the numerical data portion of the chart. The right hemisphere of your brain which is responsible for the intuitive and subjective functions will be engaged by the graphical portion of the chart.  This gives you an advantage of engaging your whole mind when it comes to trading instead of using just a section of it.

Showing Time Price Opportunity (TPO) Profile side-by-side to Volume Profile gives you a quick synopsis of

1. which price levels received the most trading volume
2. at what time during the trading session had it traded there
3. how many times it had backfilled to those price levels
4. where reversion trades worked for traders fading the move as price traded back and forth to form a cluster node
5. see where and when break-out trades occurred as price spends very little time trading there
