Audience

Purpose-built for desks, research teams, and builders.

Derivasys connects BTC and crypto volatility surface monitoring, options skew, term structure, and SVI model diagnostics without separating the fit from the market state.

Traders

See surface, skew, flies, and term structure in one live view.

Track BTC and ETH volatility moves without switching between exchange screens, spreadsheets, and model diagnostics.

Quants

Inspect SVI fits, parameters, and calibration quality quickly.

Review fitted smiles, tenor structure, quote-through-fit behavior, and surface diagnostics from the same market snapshot.

Developers

Build against compact dashboard and API-ready volatility state.

Use structured surface, smile, risk-node, and diagnostic outputs for internal tools, alerts, and downstream research.

Product previews

Start with the live dashboard, then drill into the surface.

These are the core product views: surface, risk analytics, fitted smiles, skew, flies, and calibration diagnostics. The written explainers stay further down for SEO and deeper reading.

Live monitoring

Surface state, market context, and risk nodes stay together.

Derivasys is built around the operational questions that matter during active markets: where the surface sits, what venues are quoting, and whether the fit is ready to trust.

01 / Surface

Fitted variance, smiles, and tenor structure in one view.

Monitor BTC and crypto SVI output without separating the model from the live options board.

02 / Market

Venue marks stay beside the fit.

Bid, ask, trade IV, and fit-through checks sit next to the calibrated surface.

03 / Risk

Skew, flies, and fixed-tenor slices remain inspectable.

Read risk reversals, flies, node volatility, and tenor analytics from the same market state.

04 / Diagnostics

Calibration quality is visible by default.

Queue state, update timing, fit quality, and quote-through-fit checks make the surface reviewable.

05 / API

Programmatic access is available for approved testers.

Volatility explainers

Practical guides for the surface metrics in Derivasys.

Use these pages to connect model output, smile shape, and trader-facing risk nodes before inspecting the live dashboard.

Surface

What is a volatility surface?

Start with the core concept: smiles connected across expiries into a strike-and-tenor view.

What is implied volatility?

Convert option prices into implied volatility before comparing strikes, expiries, and venues.

Forward

What is forward volatility?

Use total variance across expiries to isolate volatility implied for a future time window.

Variance

What are variance swaps?

Connect realized variance, implied variance, and the option surface behind variance-risk payoffs.

Smile

What is a volatility smile?

Read one expiry slice across strikes before it becomes part of the full volatility surface.

SVI

What is SVI?

Read the raw SVI formula, parameter meanings, BTC smile example, and production calibration checks.

SSVI

What is SSVI?

Tie SVI slices together with a surface-level total-variance parameterization and arbitrage checks.

Local vol

What is local volatility?

Use the Dupire formula to connect a smooth option price surface to model dynamics.

SABR

What is SABR/SABRE?

Understand alpha, beta, rho, vol-of-vol, and how SABR-style smiles compare with SVI.

What are risk reversals?

Use 25-delta call-minus-put volatility to read signed skew across expiries.

Greeks

What are option Greeks?

Connect delta, gamma, vega, and theta to the live volatility surface and risk-node workflow.

Fly

What are flies?

Measure wing richness and smile curvature from same-delta puts, calls, and ATM volatility.

Sticky

Sticky strike vs sticky delta

Compare listed-strike and delta-bucket conventions when the forward moves.

FAQ

Common questions.

What is Derivasys?

Derivasys is a live BTC and crypto options analytics dashboard for BTC, ETH, and altcoin volatility surfaces, SVI smiles, risk reversals, flies, fixed-tenor slices, and calibration diagnostics.

Who is it for?

It is built for traders, quants, risk teams, and builders who need fast visibility into crypto options implied volatility and surface quality.

What does SVI mean?

SVI stands for Stochastic Volatility Inspired. It is a compact parameterization used to fit implied total variance across option strikes and expiries.

Is there an API?

Yes. WebSocket and REST API access can be made available to approved testers by email.
