Lowest Low Question

[Simon Campbell <simon_campbell@xxxxxxxxxxxxxx>]

I'm writing some code on a 5 min S&P chart and have a question ...

At 10:15am I've captured the value of the highest high that occurred
between 9:45am and 10:15am (e.g. 'SimHigh' = 967.50):

For every 5 min bar between 10:15am and 12:15am, I want to check for the
following:
*  The lowest low since 10:15 only (ingoring any lows pre-10:15)
*  Is this lowest low <=Simhigh-300 points?

To avoid writing out 24 times (!!):
if t=10:15 ...
if t=10:20 ...
..etc.

is there anyway I can do this via a loop or something similar??
My problem is that the length in the lowest(price,length) function is going
to change with each bar between 10:15 and 12:15.

Any suggestions from anyone with a better programming brain than myself
will be greatly appreciated!

Simon.
