I see what you mean

"mean reversion" is the technical term you may be looking for

JustIntonation is in to that sort of thing

I know of a currency trader who uses the technique as well and when I am analysing intra day currency feeds I will at some time look into that as well

you do it by looking for bollinger band penetration on daily and then hourly time frames, then take a counter trend position with a tight stop

see the thread on this forum "software developers analysing data feeds" for who I am talking about
