Gary,
A Dx would not take 28 days to appear so its probably not that.
Warmest Regards

Subject: [Metastockusers] MetaStock ADX vs. RealTick ADX
I'm looking at using the ADX to select between a Stochastic and a moving average crossover system as appropriate for trending vs. channeling/cycling conditions. Can anyone shed some light on the difference between the ADX indicator displayed in RealTick and the ADX function in MetaStock? When I plot them on the identical price data in the two different software packages, the results are completely different. The RealTick ADX behaves as I would expect, with significant variations between higher values (> 30 or so) for trending conditions and lower values (< 30 or so) for channeling conditions. The RealTick ADX line also begins 14 days after the start of the data for a 14-period ADX. The MetaStock ADX is nearly a flat line, and begins 28 days after the start of the data (for a 14-period ADX). It looks like it's being smoothed a second time.I've done some investigation but have not yet done a spreadsheet to re-creat Wilder's formulas from his "New Concepts in Technical Trading Systems". That's my next step, but I thought someone else may have already figured it out.So far it looks to me like it's a difference in terminology - that the ADX in RealTick is actually Wilder's DX, or the MetaStock DX is actually Wilder's ADX. I also note that MetaStock's custom formula library includes a custom indicator which calculates ADX and ADXR without rounding, with the note that the built-in indicator is exactly the same as Wilder's original calculations. I wouldn't think that the rounding difference would be large enough to account for the difference between the two software packages.Thanks.Gary To unsubscribe from this group, send an email to:Metastockusers-unsubscribe@xxxxxxxxxxxYour use of Yahoo!
