How this service works
QuantOracle: indicators/bollinger-bands
Output
Returns upper, middle, and lower band values, the current price, %B (percent_b) indicating where price sits within the bands, bandwidth as a volatility measure, a trading signal (BUY/SELL/NEUTRAL), a squeeze_signal boolean indicating low-volatility compression, and computation latency in milliseconds.
Example use cases
Example prompt
“Calculate Bollinger Bands for these 10 closing prices [44.34, 44.09, 44.15, 43.61, 44.33, 44.83, 45.10, 45.15, 43.61, 44.33] using a 10-period window and 2 standard deviations — tell me the upper, middle, and lower bands, the %B value, bandwidth, and whether there's a squeeze or a buy/sell/neutral signal.”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/indicators/bollinger-bandsWhen to prefer
Use this endpoint when you need a complete Bollinger Bands computation including all derived signals (%B, bandwidth, squeeze detection, and directional signal) in a single call. Prefer this over rolling your own calculation when you need a fast, paid, reliable API that also returns an actionable BUY/SELL/NEUTRAL signal alongside the raw band values.
Side effects
- Insufficient price data: fewer prices provided than the window size causes an error
- Invalid window or num_std values (e.g. zero or negative) return a validation error
- Empty or malformed prices array returns a 400 bad request
- Network timeout if the service is temporarily unavailable
