MOO VS. LOO Orders

[Corso482]

When swing trading, and buying/selling at the open based on the previous day's data, which type of order is better, LOO (limit on open) or MOO (market on open)?

Will a MOO's get you decent fills on fairly liquid stocks (NAS, NYSE, Amex)? Or will outrageous opening fills occassionally happen, making LOO's the better choice?

I have used LOO orders with very good success. No way would I use MOO orders unless I was closing a position.

I use this all the time when trading spreads on listed stocks.
