It costs a little more ($50'ish / monthly I believe) but if identifying is a major component of your trading strategy then it's definitely worth the extra few bucks a month.......
You original post was not clear as to the timeframe you were looking for a new daily high.low, 1st hour, etc....
If you're looking for software that does nano-second high/lows then you have to get that from your platform provider (to the best of my knowledge).
I trade on Blackwood Pro and I have that nano-second (as well as the option for longer intraday timeframes) new high/low feature. Too crazy though as the stocks keep changing every split second......
The best alternative for you to get this data might be with a software vendor.
