I never open a trade live, only through a pre-set order - if price reaches a certain level. As I'm long-term trading these are daily highs or lows, which some might call minor support or resistance: either way its a kind of confirmation with a delay in-built, except that it is price-driven, not time-driven. The cost of the confirmation delay is that price has already moved towards the confirmation level before I could get in. The order stays in effect until the next daily bar prints. Although I use daily bars, I don't see why this wouldn't be of value also on intra-day time-frame charts.
