How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing: Parkinson and Garman-Klass range-based volatility estimates, realized volatility for 7-day, 30-day, and full-period windows, 30-day downside volatility, and 30-day vol-of-vol for SOL, plus an informational disclaimer.
Example use cases
Assess SOL options pricing risk
“I'm about to write some covered calls on Solana — can you pull the Parkinson and Garman-Klass vol estimates alongside the 30-day realized vol so I can tell if the options market is overpricing or underpricing risk right now?”
Compare short vs long-term volatility
“How does SOL's 7-day realized volatility compare to its 30-day figure at the moment? I want to know if we're in a vol expansion or contraction phase before I size my position.”
Evaluate SOL downside risk exposure
“I've got a big Solana position and I'm worried about tail risk — what's the current 30-day downside volatility and vol-of-vol so I can decide whether to hedge or trim my exposure?”
