Volume Profile Calculator

Approximate volume profile — point of control (POC) and value area — built from live Binance candles, since exact volume-at-price requires tick-level trade data that isn't available client-side.

This is an approximation, not a true tick-by-tick volume profile: each candle's total volume is spread evenly across its high-low range into price buckets, since Binance's public API doesn't expose where within a candle its volume actually traded. POC is the bucket with the most volume; the value area expands outward from it until it holds 70% of total volume, the standard convention.

How this approximation works

A true volume profile needs tick-level trade data — every individual trade's price and size — to know exactly where within a candle its volume occurred. Binance's public klines endpoint only reports one total volume per candle, not that internal distribution, so this calculator approximates it: each candle's volume is spread uniformly across its high-to-low range and summed into price buckets across all candles in the lookback window. The Point of Control (POC) is the bucket that accumulated the most volume — the price level the market spent the most (approximated) volume trading at. The value area expands outward from the POC, one bucket at a time toward whichever side (above or below) has more remaining volume, until it holds 70% of the total — the same convention professional volume profile tools use, just built from an approximated distribution rather than actual trade prints.

Frequently Asked Questions

Is this the same as a real volume profile?
No — it's a transparent approximation. A real volume profile is built from tick-level trade data (every trade's exact price and size), which shows precisely where within each candle volume occurred. This calculator only has each candle's high, low, and total volume, so it spreads that volume evenly across the candle's range — a reasonable estimate, but not a claim that trading was actually distributed that evenly.
Why does POC sometimes fall outside the current price?
POC reflects where the most (approximated) volume traded over your chosen lookback window, not the most recent price. If the market has trended strongly since the high-volume period, POC and the current price can sit far apart — that gap itself is often read as a signal of how far price has moved from its recent 'fair value' area.
How should I choose the interval and lookback?
Shorter intervals (15m) with a shorter lookback show a more granular, recent picture; longer intervals (4h, 1d) with a longer lookback approximate a higher-timeframe profile useful for swing-level support/resistance. There's no single correct setting — traders typically match the lookback window to the timeframe they're trading.
