Would like to be able to calculate the Ulcer Index of various time frames in TC2000.  Any help creating these formulas would be greatly appreciated.  Thanks!

Given a specific period, it would be possible to the Ulcer Index (the referenced topic is for StockFinder, but the algorithm would be straightforward to convert). It is not possible to create a generalized solution which would accept a period as a user input in TC2000.

ulcer index in SF 4

Okay, so showing how much of a noob I am here...  can you point me to some resources to get a better handle on how to code this thing?  I'm completely unfamiliar with the language and the various products offered through Worden.  I'd like to be able to create a few different UI time periods -- like 5, 10, 17, 21, 40, 100, etc...  I just need a little more of a nudge in the right direction.  I 'conceptually' understand the other thread, but I don't know how to translate of actually get the code started.

Thanks for the response Tom!

My interpretation of 5-Period Ulster Index as an Indicator Formula is:

(ABS((C < MAXC5) * (100 * (C / MAXC5-1)) ^ 2 - (C1 < MAXC4.1) * (100 * (C1 / MAXC4.1 - 1)) ^ 2 - (C2 < MAXC3.2) * (100 * (C2 / MAXC3.2 - 1)) ^ 2 - (C3 < MAXC2.3) * (100 * (C3 / MAXC2.3 - 1)) ^ 2 - (C4 < C5) * (100 * (C4 / C5 - 1)) ^ 2) / 5) ^ .5

My interpretation of 100-Period Ulster Index is too long and slow to post in the forums.
