One approach that would need to be updated each week would be to
define a 2 dimensional array. One dim being the weekly high, the other dim
being the weekly closing date. ( Or may this two single dimension arrays.
For each 5 min bar, scan the array 52 elements backward from the date that is
less than the 5 min date. As you scan, keep track of the highest high,
then compare.
Another approach woiuld be to store weekly prices and times in memory from a
weekly chart through a DLL. Then read memory from the 5 min chart to find
the 52 week high for the comparison.
In the above approaches, you would also have to scan the current week's highs
to see if they exceeded the last 52 weeks.
