thx WB / cnms - not long ago i put together some numbers looking at - the greeks, individual option strip liquidity / bid-ask spread, ultimate risk exposure (i.e. option premium), effect of commissions, choice of option expiry dates, expected duration of a trade, among others - there seemed to be too many variables to come up with a definitive algorithm selecting the most effective option to trade - in the end, i ran a few simplified scenarios and concluded that in general, for trades with duration of several days, ATM and/or slightly ITM options looked most effective in terms of replicating the performance of the underlying (S&P index) while limiting max risk exposure to the option premium.. - thx again for the feedback and all the best.
