OPT_PROB_HIT function

OPT_PROB_HIT

Returns the probability that an asset hits a predetermined barrier price, assuming that the stock price can be modeled as a process S that follows the stochastic differential equation, as follows. OPT_PROB_HIT equation µ is the asset’s percentage drift, vol is the percentage volatility of the stock, and dW is a random sample drawn from a normal distribution with a zero mean. W is a Wiener process or Brownian motion.
OPT_PROB_HIT(Spot; Volatility; Drift; Maturity; Lower Barrier; Upper Barrier) Drift is the annual stock price percentage drift rate (µ in the above formula). The value is expressed as a decimal (for example, enter 15% as 0.15). Strike is the strike price of the option and should be non-negative. =OPT_PROB_HIT(30,0.2,0.3,1,0,40) returns the value 0.6119. =OPT_PROB_HIT(70,0.3,0.1,0.5,60,0) returns the value 0.4239.
