@SYNTAX=OPT_BS_DELTA(call_put_flag,spot,strike,time,rate,volatility[,cost_of_carry])
@DESCRIPTION=OPT_BS_DELTA uses the BlackScholes model to calculate the 'delta' of a European option with call_put_flag, @call_put_flag, 'c' or 'p' struck at @strike on an asset with spot price @spot.
Where @time is the time to maturity of the option expressed in years.
@rate is the riskfree interest rate.
@volatility is the annualized volatility, in percent, of the asset for the period through to the exercise date.
@cost_of_carry is the leakage in value of the underlying asset, for common stocks, this would be the dividend yield.
* The returned value will be expressed in the same units as @strike and @spot.
