Market Profile
Market Profile is a chart of how long the market traded at each price. It stacks a letter for every 30 minutes at the prices traded, so a session's shape shows where buyers and sellers agreed on value and where price was rejected.
Time at price, not price over time
A candle chart puts time along the bottom and shows where price went. Market Profile turns that around. It asks a different question: at each price, how much time did the market spend there?
Each 30-minute period gets a letter. A is 09:15 to 09:45 on NSE, B is 09:45 to 10:15, and so on. Every price the market traded during a period gets that period's letter. Stack the letters at each price and the session takes a shape.
Wide rows are prices the market kept coming back to. Thin rows are prices it passed through quickly. That difference is the whole idea.
Every session is an auction
Market Profile was developed by J. Peter Steidlmayer, a trader on the Chicago Board of Trade, in the 1980s. It rests on one observation: the market is an auction. Price moves up to find sellers and down to find buyers, and it stops where trade gets easy.
When price finds a level both sides are happy to trade at, it stays there and letters pile up. When one side stops responding, price moves on to look for the other side.
Read a profile this way and every session tells a story. Where did the auction go looking? Where did it find agreement? Where was it turned away?
Value: where both sides agreed
The value area is the band of prices holding about 70% of the session's letters. Inside it, buyers and sellers were both willing to trade for a long time. That is what the market accepted as fair.
The single busiest price is the point of control, the POC. On the morning shown here it is 24,070, with value from 24,060 to 24,135.
Value matters most the next day. A market that opens inside yesterday's value is still agreeing with yesterday. One that opens outside it has to prove the new price, by building value there or by coming back.
The edges tell you what is unfinished
The thin edges of a profile matter as much as the fat middle.
A run of prices traded in only one period is a single print: the market moved through so fast that no second period came back. Single prints at the very top or bottom of a session are a tail. A tail means the auction found a price one side refused and was pushed away hard.
A flat edge with no tail is the opposite: a poor high or poor low. The auction stopped without a clear rejection, and price often comes back to finish it.
Reading NIFTY with Market Profile
For NIFTY and BANKNIFTY the first hour sets the frame. The initial balance is the range of the A and B periods, 09:15 to 10:15. A narrow initial balance usually leaves room for the day to extend; a wide one often contains most of the day.
On the morning shown, the first hour ran from 24,071 to 24,153.9. In C the market extended below that range, and it found its low in E before buyers took it back.
From here, learn the pieces one at a time: the TPO chart itself, the value area, the POC, the initial balance and the NSE session clock.
Lessons, in order
- TPO chartWhat a TPO chart is, how the letters are built from 30-minute periods, and how to read a NIFTY TPO profile - with a real session.
- Value areaThe value area in Market Profile: what VAH and VAL mean, why 70%, and how NIFTY traders use yesterday's value to read today's open.
- Point of control (POC)The point of control in Market Profile: the fairest price of the session, how it moves, and why naked POCs from past NIFTY sessions matter.
- Initial balanceThe initial balance in Market Profile: the first hour's range on NSE (09:15-10:15), range extensions, and what a wide or narrow IB says about the NIFTY day.
- NSE session times for Market ProfileThe NSE session for Market Profile traders: 09:15-15:30 IST, the TPO letters A to M, the 09:15-10:15 initial balance and the 15:30-15:40 closing session.

What is Market Profile in trading?
A way of charting a session by the time spent at each price. Letters for each 30-minute period stack at the prices traded, showing value (where the market accepted price) and rejection (where it moved away fast).
Who invented Market Profile?
J. Peter Steidlmayer, a trader at the Chicago Board of Trade, developed it in the 1980s. The CBOT later published it, and James Dalton's books made it widely known.
Does Market Profile work for NIFTY and BANKNIFTY?
Yes. The ideas are the same for any auction market. On NSE the letters follow the 09:15 to 15:30 session, and the first hour (A and B) is the initial balance.
Is Market Profile the same as Volume Profile?
No. Market Profile counts time at each price; Volume Profile counts contracts traded at each price. They often agree, and where they disagree is itself information.
