I thought this was interesting, but am not a big options trader so maybe it isn't a big deal?

optionsXpress new "Walk Limit" for Options

Stops you from having to do it manually.

Sort of what you do to 'work an order' by hand to get a better price especially on things with larger bid/ask spreads.

I never used the Walk Limit Order feature on OX. I normally prefer to change manually and look for the mid price between the bid/ask. Does someone here use WLO often and can share his experience using it? when to use? when to avoid it? how effective is it? etc.
I talked with few traders with OX account and realized that I'm not the only one that never bothered using it, but OX makes such a fanfare of this feature that I wonder if I am missing something.

I would love to hear from someone that has used WLO often.
