ETH: Options Vega Traded (Deribit)
Shown as its 3 Oct – 1 Nov 2026 sample; the latest readings and full history are included with Pro.
The volatility exposure traded through ETH options on Deribit, in USD per one volatility point: all vega traded and the net vega bought by takers.
Why use it. Vega is how much an option position gains or loses when implied volatility moves one point; heavy taker buying of vega tends to lift implied volatility, heavy selling tends to press it down. How to read it. Net above zero: takers bought volatility; below zero, they sold it. Compare with the implied-volatility charts to see whether a vol move was driven by flow.
Calculation. For each trade: Black-76 vega per volatility point on the trade's implied volatility with the index price standing in for the forward, times the contracts; signed by the taker's side for the net line, unsigned for the total. Trades without an implied volatility on record count toward the volume charts but not here.
