The Omengraph Volatility Index (OGVI) is a real-time composite indicator measuring global market volatility across crypto, forex, equities, and commodities. It is calculated using the Avaltix Probabilistic Engine.
The OGVI uses a fuzzy logic inference system that weighs multiple volatility indicators:
OGVI = Σ(w_i * f_i(x)) / Σ(w_i)
Where:
- w_i = weight of indicator i
- f_i(x) = fuzzy membership function output
- x = raw indicator value
| OGVI Range | Severity | Market Condition |
|---|---|---|
| 0 - 30 | LOW | Calm, low volatility |
| 30 - 50 | MODERATE | Normal market conditions |
| 50 - 70 | ELEVATED | Increased uncertainty |
| 70 - 100 | HIGH | Extreme volatility, risk-off |
