BB Width API — Detect the Squeeze Before the Pop
Bollinger Band Width = (upper − lower) / middle. Watch it compress to detect low-volatility coiling — a precursor to breakouts.

What is the BB Width API?
Bollinger Band Width measures the percentage distance between the upper and lower Bollinger Bands relative to the middle band: (Upper − Lower) / Middle × 100. When BB Width contracts to its lowest point in a given period, a volatility squeeze is forming — historically a precursor to a significant directional breakout. Our API delivers the current width value, individual band levels, and a squeeze signal so your bot can detect and trade breakouts programmatically.

Frequently Asked Questions
How is BB Width calculated?
BB Width = (Upper Band − Lower Band) / Middle Band × 100. The Bollinger Bands use 20-period SMA as the middle band, with upper and lower bands set at 2 standard deviations. Our API pre-calculates this using broker candle close prices.
What qualifies as a 'squeeze' signal?
The API classifies a squeeze when the current BB Width is near its lowest value over the lookback window — indicating unusually contracted bands relative to recent history. When the squeeze ends and width expands, that is typically the breakout entry.
Can I use BB Width history to identify past squeezes?
Yes — use GET /v1/indicator/history with indicator=BB_width. Plot the width series to find historical squeeze lows. This is useful for understanding how long squeezes typically last on a given symbol/timeframe before breaking out.
Does the response include the band levels?
Yes. The BB_width response includes bb_upper, bb_lower, and bb_middle — so you get the squeeze detection signal AND the exact price levels to set bracket orders around, all in one API call.
