Kim,
I have written two identical versions of the same indicator. One stores
data to and retrieves data from a multi-dimensional array in TS, the other
stores/retrieves data to/from the HashNums DLL, specifically using the
functions that store and retrieve by index number i.e. putNo("High", 1,
1080) and getNo("High",1). I stored the "array data" in the HashNums DLL
not in a .csv file. Otherwise the code is identical. I processed the exact
same data i.e. a daily chart, used the exact same loop structures and
bubbled down the arrays the same way. The HashNums version is many, many
orders of magnitude slower than the TS version on my computer (Pentium 150
MHz, 512 KB cache, 128 MB RAM in Win95). It's so slow that I wouldn't even
attempt it on a real-time chart. The only problem with the TS version is
the 64K limit which prevents me from adding everything I want.
If however you have any insight into interfacing HashNums with VB so that
data could be passed from TS to HashNums, processed in VB, returned to
HashNums and imported back into TS then I'd be interested in learning how.
There are several programming hurdles that need to be overcome to do this.
The HashNums on-line manual is very ambiguous on this matter.
Sincerley,
Mark.
