Volatility, funding basis & market mechanics

Check the terms. Control the execution.

Check volatility, funding and potential costs before committing collateral. Keep your wallet disconnected until you need to authorize an order.

These pre-trade calculators illustrate mechanics. They do not execute orders, reserve collateral or change your contract terms.

30-day implied volatility

Track BTC and ETH volatility expectations using an external 30-day options index. Check how different assumptions change an expected price range.

Check volatility ↗Reference index only. Not a darkoptions tradable volatility contract.

Funding-rate basis

Compare funding estimates from external perpetual markets on a shared eight-hour basis to understand potential hedge carry.

—BTC · bps / 8h · A − B

Compare funding ↗Predictions can change. No Robinhood-native rate is used. Bars show magnitude; numbers preserve the sign.

Capped-payout model

Interactive model

Adjust a hypothetical profit cap up to 8× initial margin and inspect its modeled reserve requirement. This cap does not apply to your trades.

Initial margin (USD)Available model reserve (USD)

Profit cap 8× margin

Maximum modeled profit: $800.00
Margin + maximum profit: $900.00

Model reserve covers the profit cap.

No capital is reserved by this calculator. Gross return assumes the margin is returned.

Oracle dampener model

Interactive model

Apply a price shock and compare the incoming price with a filtered response. Moves within 20% pass through; larger moves take a 5% step, capped at 20% per update.

Starting reference priceIncoming price shock +90%

+4.50%First filtered update · $104.50

Solid: filtered · Dashed: incoming12 modeled updates

Illustrative filter, not the oracle used by current positions. Filtering delays real price changes and does not guarantee protection.

Skew-based borrow-fee model

Interactive model

Calculate how market imbalance changes a hypothetical borrowing cost. The crowded side’s rate rises with the square of the larger-to-smaller position ratio.

Position split 80% long / 20% short

Base daily rate (bps)Crowded-side notional (USD)

Imbalance multiplier: 16.00×
Modeled paying side: Long
Modeled daily cost: $16.00

At 50/50 neither side pays. Otherwise only the crowded side pays in this model. This tool charges no fees.

How these tools relate to your options

The volatility panel uses an external 30-day implied-volatility index; it is not a darkoptions-issued C-VIX variance-swap contract. The funding-rate basis panel compares external estimates; it is not a tradable FR-BASIS contract or a Robinhood-native funding benchmark. The three models do not change contract payoffs, oracle prices, liquidation rules or execution fees. Their charts are calculated from your inputs. No orders or wallet signatures are requested.
