| RV | 434% | Realized Volatility — annualized stddev of returns from 48h price history |
| VR | 3.14 | Vol Ratio — realized vol / theoretical max. >0.8 very active, <0.1 dead |
| IAR | 1.4/h | Info Arrival Rate — meaningful price changes per hour (48h window) |

LAS / CVR are null because this market is outside the warm-regime cron's top 500 by 24h volume. Coverage is sparse by design.
