How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
Returns a JSON object with Hurst exponent values for BTC across three time windows (7d, 30d, full) and a human-readable interpretation for each: 'trending', 'mean_reverting', or 'random_walk', plus a disclaimer that the data is for research purposes only.
Example use cases
Detect Bitcoin's current market regime
“Is Bitcoin currently in a trending regime, a mean-reverting phase, or just random noise? Check the Hurst exponent across the short and long windows and tell me what kind of price behavior we're seeing right now.”
Filter trading strategy by BTC dynamics
“Before I run my momentum strategy on Bitcoin, I want to know if BTC is actually trending or just doing a random walk — can you pull the Hurst exponent data and tell me whether conditions favor a trend-following or mean-reversion approach?”
Research Bitcoin fractal price behavior
“I'm doing some quant research on Bitcoin price dynamics — can you grab the Hurst exponent values for the 7-day, 30-day, and full historical windows and summarize whether BTC is showing persistent, anti-persistent, or random behavior across each timeframe?”
