A working tool for index options traders who would rather know than guess
Trading options on an index is, at bottom, work with ranges and probabilities. Most traders decide on a feeling about how far the index "might move", without structured access to a record of what it actually did. WolfStalk was built to close exactly that gap.
What the product does
It joins two things that usually live apart: a workspace where you build a position and see its profit-and-loss profile, and a historical database that lets you test the assumption the position rests on. That join is what turns a theoretical exercise into a decision tool.
The simulator
Multi-leg positions on any listed expiration, an interactive payoff chart, break-even points, maximum profit and loss, and a wizard with 14 built-in structures.

Fifteen years and 3,770 trading sessions of SPX, SPY, QQQ and NDX history, broken into move distributions, day-of-week cuts, short-dated versus monthly comparisons and day pairing.

Questions about a position you built or about the historical record, answered with a pointer to the figure the answer came from.

A number beats a feeling
Every claim in the product rests on a figure you can point at. When a hit rate is shown, it is clear which population of expirations it was computed over and across which date range. There are no metrics that cannot be decomposed back into the raw data.
Honest about limits
We say plainly what is missing — licensed historical option premiums, and a per-strike implied volatility with the skew that comes with it — instead of implying it exists. Greeks are computed, and the screen that shows them says which volatility index they came from. A tool that inflates its own capabilities makes its users take risk they are not aware of.
Standard vocabulary
Strangle, straddle, vertical spread, iron condor, iron butterfly, ratio spread, collar. The product speaks the language US options traders actually use, in both English and Hebrew.
Simulation, not advice
WolfStalk is not a broker, does not execute trades and does not manage money. It shows what a position is worth at every index level and what happened historically. The decision stays with the user, and so does the responsibility.
Who it is for
New options traders
Understand exactly what a vertical spread or a strangle does at every index level, before taking a live position. The strategy wizard teaches the structures through concrete examples.
Active traders
Calibrate range width and position size against the historical distribution of moves, and run several portfolios in parallel with running profit and loss.
Strategy testers
Examine how a structure would have behaved across different market regimes, and compare short-dated expirations against monthlies on the same assumption.
