Simulator · no wallet, no contract calls

Know the strike before you trade.

Pick a Stock Token at its live price. The perps tab uses the exact integer maths of the desk contract (StrikePerps). The options tab draws the payoff at expiry; it is a calculator only, Strikeloom does not sell options.

Funding is not included: it is paid by the heavier side of open interest to the pool (up to 20%/yr at full skew), so it depends on other traders. Profit is capped at the position size. Prices gap at the Monday open; a liquidation price is not a stop price.
