Market Indices

Three cryptographically signed composite indices — volatility, sentiment, and stress — each telling a different part of the same market story.

Overview

Mycelia Signal publishes three signed composite indices. Each measures a distinct dimension of market state. Used together, they give a complete picture of current conditions that no single number can provide.

Reading Them Together

MSSI and MSXI are most powerful in combination. MSSI tells you about structural conditions; MSXI tells you about positioning. The four quadrants describe meaningfully different market regimes.

MSVI — Volatility Index

MSVI measures how much the market is moving, and how extreme that volatility is relative to history. It is the only cryptographically signed composite crypto volatility oracle — five independent signals combined into a single Ed25519-attested number on every paid query.

VIX tells you how scared the S&P options market is. MSVI tells you how scared the crypto market is — and proves it with a signature you can verify independently.

The Five Components

Output scale

MSVI outputs a 0-100 bounded index using min-max normalization against a rolling 2-year history window. Higher values indicate elevated volatility. Lower values indicate calm. During the first 30 days, MSVI outputs raw component values while history accumulates — the normalized field in the response indicates which mode is active.

MSXI — Sentiment Index

MSXI measures directional market positioning across five independent signals. The sign carries meaning — positive values indicate net bullish positioning, negative values indicate bearish positioning, and the magnitude reflects conviction.

MSSI — Stress Index

MSSI measures systemic market stress independent of price direction. A high MSSI reading indicates the market is structurally fragile — elevated volatility, stablecoin peg pressure, or extreme funding positions that increase liquidation risk. MSSI does not predict price direction; it predicts the potential severity of dislocations if they occur.

Backtest & Validation

We have validated the components with available public historical data from January 2020 to present. The backtest covers realized volatility (Parkinson estimator), funding rates (Binance), and stablecoin peg data (USDC/USDT). Components derived from the Deribit options book — skew, PCR, and term structure — require historical options snapshots not available via public API.

The options-derived components are accumulating history from the live environment from launch. A full methodology validation including these components will be published as sufficient history accumulates.

* FTX MSXI showed BULLISH on collapse day — funding went extreme negative (shorts piling in), which reads as a contrarian oversold signal. Technically valid as a mean-reversion signal; directionally misleading as a sentiment label. Documented limitation of funding-direction component during sharp counterparty events.

MSXI partial backtest covers funding rate direction and RV-proxy components only. Full 5-component backtest requires historical Deribit options data.
