I am having trouble using the fisher transform(10). The values it returns and plots are not the same as fisher transform on other platforms? They are far less in magnitude. Any idea why that would be? Is there a different fomula being used? Thanks

A pseudo Personal Criteria Formula for the Fisher Transform could be written as:
XAVG(LOG(XAVG(2 * ((H + L) / 2 - MINL10) / (MAXH10 - MINL10) - 1,5)),3)
But you are not actually allowed to include formulas or other functions within an XAVG() function, so the above syntax is not valid.
Note that this is not an Inverse Fisher Transform (of RSI) or a Smoothed Inverse Fisher Transform of RSI (which is available in StockFinder). These IFT of RSI indicators both have much larger magnitudes than the Fisher Transform. Neither of these indicators are currently available in TC2000.

Thanks Bruce. I wasn't asking for a formula--rather just wondering why the indicator which is already programmed by TC does not give values that are consistent with other platforms. Maybe the answer lies in the formula above. I will check it out.

I cannot speak for other platforms. I can only speak for our products. Fisher Transform is based on the article "Using The Fisher Transform" by John Ehlers in the November 2002 issue of Stocks and Commodities Magazine.
