PARABOLP² × carry factor
A 20% price rise increases value by 44% before costs. Falling prices also amplify losses.

STATIC ESTIMATEBear² allocation needed961.00virtual USDG
Assumes simultaneous entry. Excludes carry and trading fees. Bear² stops gaining once the price reaches its floor.
Three directions. One model.
MODEL / 011 / max(P, floor)²
Value rises as the price falls, caps at the market floor, then adjusts for carry.
½ Bull² + ½ Bear²
An equal-weight mix of both sides. Some upward and downward moves can generate gains; carry still reduces value.
P is the current price divided by the position’s entry price. Carry factor = (1 − daily carry) ^ days held.
A few things to know before you start.
Can I deposit real money here?
This is an independent concept demo and trading simulator. It accepts no deposits, executes no onchain trades, and is not an official product of the original Parabol project.
Why did my position lose value while the price stayed flat?
Daily carry compounds over time. Use the clock controls at the top to see its effect. Bull² and Bear² have different daily carry rates.
What is the maximum Bear² payoff?
In this model, NVDA, TSLA, and PLTR have a 50% relative price floor, capping value at 4× the stake before costs. AAPL has a 60% floor and SPY a 70% floor. Each position uses its own entry price; carry reduces its simulated value.
