Why TickAtlas
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.

What developers ask first.
Straight answers on limits, coverage and how the endpoint behaves in production.
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 candle close prices from our data.
What qualifies as a 'squeeze' signal?
There is no squeeze flag in the response — BB_width is a number. A squeeze is when the current BB Width sits near its lowest value over your chosen 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?
Not from the BB_width call itself — /v1/indicator returns one value per request. Use GET /v1/indicators?symbol=EURUSD&timeframe=H1&category=volatility instead: BB_upper, BB_middle, BB_lower and BB_width come back together in the indicators map, so you get the band levels to set bracket orders around in one call.
