Markets made from markets.

One asset, priced in another.

Every market on Otus is a ratio. Not the price of one thing. The relationship between two.

relativePrice(A, B) = price(A) / price(B)

The ratio rises when the base asset outperforms the quote asset, including when both are falling. A market can be up while the whole market is down, because it was never about direction. It is about who wins.

NVDA/TSLA

Live

0.56159

−1.82%24h

One share of NVDA, priced in TSLA. Real verified Solana assets, real onchain prices. This number is live.

The two-leg trade is broken.

Traders already fake relative positions with two opposite perps. Otus exists for everywhere that fails.

Liquidated by a wick

Fake the trade with two opposite perps and a market-wide crash blows up the long leg before the short leg pays out, even when the view was right. A ratio position has one liquidation level, and it is a ratio.

Drift needs babysitting

Two legs fall out of balance as prices move and need constant rebalancing. A ratio position cannot drift. It is the relationship itself, balanced by construction.

Double margin, double fees

Two positions cost twice the collateral, twice the fees and twice the funding. One position halves all three.

Pairs that cannot exist

Many relationships cannot be assembled from perps at all, because one side has no perp market. Tokenized equities and long-tail Solana assets first among them.

How it works · 01

Two assets

NVDA has a chart. TSLA has a chart. Two separate stories, two separate trades.

How it works · 02

One market

Divide one by the other and the two charts become one: the ratio, indexed to 100. It rises when NVDA outperforms, even if both are falling.

How it works · 03

Pick the winner

Back a side. TSLA is ahead by 6.48% over the last month, live. If your side outperforms, you profit, whatever the market as a whole is doing.

How it works · 04

Set leverage

Ratios move quietly, so leverage does the work: that 6.48% becomes 64.8% at 10×. Entry and liquidation are ratio levels, indifferent to a market-wide crash.

Pairs that exist nowhere else.

SOL against NVDA. BTC against MSTR. A broker cannot offer them, an exchange cannot offer them, and two perps cannot build them. Solana is where both asset types already live.

High leverage that survives the crash.

Ratios move far less than prices, which is exactly what makes leverage safe to hold, and necessary to make small relative moves worth trading.

A token, in a bad week

−40%

Its ratio against a peer, the same week

−6%

Both assets crash; the relationship barely moves. That is why a ratio supports leverage a single price never could. An Otus liquidation level is a ratio level, indifferent to what the whole market is doing. Illustrative figures.
