Yearly Anchored VWSTD (Volume-Weighted StdDev Bands)

13 Eki

This indicator calculates a Volume-Weighted Mean Band (VWMB) — similar in concept to an anchored VWAP — and measures standard deviation from the mean to visualize how far price has deviated from its volume-weighted equilibrium.

Each calendar year acts as an anchor period: the cumulative calculations reset automatically on January 1st, providing a fresh annual reference.
At any time, the middle yellow line represents the volume-weighted mean price (VWMP) since the start of the current year, while the surrounding ±1σ, ±2σ, and ±3σ bands show progressively stronger deviations from that mean, taking both price and volume into account.
