AR OptionSim

iOS Universel / Finance

AR OptionSim is an app that lets you simulate and visualize option prices and Greeks in augmented reality. The program implements the Black-Scholes model and supports both one-asset vanilla and two-asset basket European call/put, with and without barrier(s).



The Black-Scholes partial differential equation is solved using the finite element method with implicit Euler time integration. The simulation algorithm also leverages GPU acceleration with Metal Shading Language. Please see details below for information on settings and supported option types.

Settings:
- One-Asset Mode
K: Option Strike Price (A range of underlying asset prices are automatically calculated based on the option’s strike price)
B1: Lower Knock-out Barrier Price (Optional)
B2: Upper Knock-out Barrier Price (Optional)
T: Time to Expiration
σ: Volatility
δ: Dividend Yield
r: Risk-free Interest Rate
Steps: Number of Simulation Timesteps (Increase the number of timesteps to increase simulation accuracy and stability)


- Two-Asset Mode
K: Option Strike Price (A range of underlying assets prices are automatically calculated based on the option’s strike price)
B1: Lower Knock-out Barrier Price (Optional)
B2: Upper Knock-out Barrier Price (Optional)
T: Time to Expiration
σ1: Volatility of Underlying Asset 1
σ2: Volatility of Underlying Asset 2
δ1: Dividend Yield of Underlying Asset 1
δ2: Dividend Yield of Underlying Asset 2
ρ: Correlation Coefficient Between Underlying Asset 1 And Underlying Asset 2
r: Risk-free Interest Rate
Steps: Number of Simulation Timesteps (Increase the number of timesteps to increase simulation accuracy and stability)


Color Mode:
- Normal: Heat map based on the option prices on the simulated price surface
- Curvature: Heat map based on the mean curvature of the simulated price surface


Interaction:
- Drag on the plot with one finger to see prices and Greeks
- Move, rotate, or scale the plot with two fingers


Supported Option Types:
- Vanilla European Call/Put (One-Asset)
- Down-and-out European Call/Put (One-Asset)
- Up-and-out European Call/Put (One-Asset)
- Double-Barrier European Call/Put (One-Asset)
- Basket European Call/Put (Two-Asset)
- Down-and-out Basket European Call/Put (Two-Asset)
- Up-and-out Basket European Call/Put (Two-Asset)
- Double-Barrier Basket European Call/Put (Two-Asset)


Supported Greeks for Interactive Visualization:
- One-Asset: Delta and Theta (Δ & Θ)
- Two-Asset: Deltas with respect to the two underlying assets (Δ1 & Δ2)
