Currently, the API does not implement authentication. For production or public-facing deployments, we strongly recommend integrating a secure method (e.g., API keys, JWT tokens) to control access.

Delta is a volatility measure used to model price uncertainty over time. It represents the average absolute percentage change in price over a given window.
Step 1: For each pair of consecutive average prices P[t] and P[t+1], compute the absolute percentage change:
delta_t = abs((P[t+1] - P[t]) / P[t])
Mathematically:
deltaₜ = |P[t+1] - P[t]| / P[t]
Step 2: Take a rolling average of delta_t over a window (default: averaging_range = steps / 2). This smooths out short-term noise:
rolling_delta = delta_series.rolling(window=averaging_range).mean()
