Oddly I to found I got faster fills WITH an "all or none" restriction. Back in the day...if you added a restriction a real live human worked your order and usually you just see smaller trades going off all around your price and you never get a fill and your broker will use the "excuse" your order qualifier no longer entitles you to compare versus Time and tape market type orders. I've been in compliance for 5 years, in that time all the rules have been re-written. Just odd....
