Jut an update for anyone using eSignal with a similar problem. Use a 390 min chart (the number of mins in NYSE trading session) and set you time to the correct session and you get a pretty decent representation of the real highs and lows of daily spread bars.
One problem I ran into is that eSignal only has 120 days of intraday data in the standard data subscription, so I've added extended data which gives you more than enough intraday. Once you construct these bars you can export the data into a spreadsheet as well for analysis.
I usually only use this when I absolutely have to, otherwise eSignal gets really bogged down.
I hope this helps.
