Digital Option Pricing Engine using Monte Carlo Simulation. The B-S model is used to describe dynamics of undelying asset price.


DT supported data type including double and float data type, which decides the precision of result, default double-precision data type.
UN number of Monte Carlo Module in parallel, which affects the latency and resources utilization, default 10.
underlying intial value of underlying asset at time 0.
volatility fixed volatility of underlying asset.
dividendYield the constant dividend rate for continuous dividends.
riskFreeRate risk-free interest rate.
timeLength the time length of contract from start to end.
strike the strike price also known as exericse price, which is settled in the contract.
cashPayoff fixed payoff when option is exercised.
exEarly exercise early or not, true: option exercise at anytime. false: option only exericse at expiry time.
optionType option type. 1: put option, 0: call option.
seed array to store the inital seeds for each RNG.
output output array.
requiredTolerance the tolerance required. If requiredSamples is not set, when reaching the required tolerance, simulation will stop, default 0.02.
requiredSamples the samples number required. When reaching the required number, simulation will stop, default 1024.
timeSteps the number of discrete steps from 0 to T, T is the expiry time, default 100.
maxSamples the maximum sample number. When reaching it, the simulation will stop, default 2,147,483,648.
