Market Profile TPO [vault]

TPO [vault] is a market profile tool that shows where the market actually spent its time, not just where price printed a candle. It builds a time price opportunity profile for every day, week or month and marks the levels that keep mattering after the period closes.

How it works

The script splits each period's range into a configurable number of rows and counts how many bars traded inside every row. That count is the TPO score. The widest row is the Point of Control, the fairest price of the period and the level price keeps rotating back to. Around it the script expands the Value Area using the standard two row algorithm until it holds a chosen percentage of total TPO count, giving you the accepted range and its two edges.

Everything is calculated in a single pass over the period's bars instead of scanning every row separately, so the developing profile updates in real time without dragging the chart down, even on 100 rows and low timeframes.

Green area below, red above, no. This is not a signal tool. Value area high and low are the edges of accepted price, and trades that open outside value and reject back inside tend to rotate to the opposite edge. The POC is a magnet. Untouched POCs from previous periods are stronger magnets.

What it draws

- Full TPO profile per period, D, W or M, with adjustable row size and profile width
- Point of Control line, ties resolved toward the middle of the range so the POC never sticks to an extreme
- Value Area high and low with optional shaded background
- Initial Balance, the range of the first balance window of the session, with optional extension across the whole period
- Single prints, the thin one row areas left by one sided moves, top and bottom tails excluded by design
- Naked POC, previous POCs price never traded back into, extended right until they get hit and then removed automatically

Reading it

Value area edges are where acceptance starts and ends. Initial Balance tells you the shape of the day early: price holding inside IB all session is a rotation day, a break of IB high or low with follow through is the classic trend day tell. Single prints mark unfinished auction, the market moved too fast to trade there and usually comes back. A naked POC sitting above or below current price is an obvious target for the next rotation.

Additional settings

- Profile period: D for day trading, W or M for swing context
- Row size: higher for precision, lower for speed on long periods
- Value Area %: 70 is standard, some traders use 68 or 80
- IB session and timezone: defaults to 0930 to 1030 New York, the RTH open hour for US index futures. Set it to your own instrument's open
- Profiles kept on chart: old profiles are deleted as a whole group, so the script never hits TradingView drawing limits and never leaves half a profile behind
- Min rows per single print: filters out one row noise, 2 or 3 keeps only meaningful gaps
- Show developing profile: toggle the live, still forming profile
- Level labels with prices for POC, VAH and VAL
- Full color, width and line style control for every element
- Built-in alerts for prior POC, VAH and VAL crosses and for IB high and low breaks
- Works on any instrument, requires a chart timeframe lower than the profile period
