OPT_BARRIER(Spot; Volatility; Rate; Foreign Rate; Maturity; Strike; LowerBarrier; UpperBarrier; Rebate; PutCall; InOut; BarrierMonitoring [; Greek])

Spot is the price / value of the underlying asset and should be greater than 0.0.

Volatility is the annual percentage volatility of the underlying asset expressed as a decimal (for example, enter 30% as 0.3). The value should be greater than 0.0.

Rate is the continuously compounded interest rate. This is a percentage expressed as a decimal (for example, enter 40% as 0.4).

ForeignRate is the continuously compounded foreign interest rate. This is a percentage expressed as a decimal (for example, enter 50% as 0.5).

Maturity is the time to maturity of the option, in years, and should be non-negative.

Strike is the strike price of the option and should be non-negative.

LowerBarrier is the predetermined lower barrier price; set to zero for no lower barrier.

UpperBarrier is the predetermined upper barrier price; set to zero for no upper barrier.

Rebate is the amount of money to be paid at maturity if the barrier is hit.

Put or Call is a string that defines whether the option is a put (“p”) or a call (“c”).

InOut is a string that defines whether the option is knock-in (“i”) or knock-out (“o”).

BarrierMonitoring is a string that defines whether the barrier is monitored continuously (“c”) or only at the end / maturity (“e”).
