AlphaRange/Tools/Polymarket hedge lab

LP tail-hedge scenario lab

See how a concentrated LP, a partial short perpetual, and a modeled downside prediction token respond as price and time change.

Demo fallback datamedium confidence

Demo fallback — ETH below $2,700 at expiry

Compare the LP's curved downside with a linear partial short and a bounded-cost downside token. The Polymarket line is an analytical mark anchored to the supplied midpoint, not a promise that future bids will exist at that price.

Checking current Polymarket markets…

Strategy in plain English

The perp reacts to every move. The digital can react less near today's price, then accelerate as spot threatens the LP boundary. You give up continuous protection in exchange for bounded premium risk and protection concentrated near a chosen strike.

Scenario lines use modeled marks. Only the current executable card above uses an observed bid; future executable prices require a future order book and may be materially worse.

Assumptions

  • • The market is a terminal ETH-below-strike contract; touch or barrier rules need a different model.
  • • The digital curve is anchored to the current fixture midpoint with a constant log-odds offset.
  • • Projected LP fees accrue linearly through the selected elapsed day; actual in-range time may be lower.
  • • The perp is a 50% short against the LP's initial ETH amount and excludes funding, liquidation, and trading costs.
  • • Only today's best bid is treated as executable; future scenario marks do not assume future order-book depth.
