Hi,
I have checked out Jose MetaStock website :)
Really good reference for a rookie like me.
Thanks for advice

inspiration, and I agree with Jose that the gradient depends on the X-
axis timescale, "averaging interval", or "smoothing period" that is
used. However, as a trader, investor and project manager, I have some
slightly different ideas regarding objective measurements for
gradient plots. Personally, I use the Annualized ROI% (annualized
percentage Return on Investment) concept, in which the percentage
price change is converted to a common objective measure that can then
be used for validly comparing all stocks, indices, futures, FX
trades, project returns, etc.

period as a whole year, but rather that, whatever averaging period
you take, the result is then converted to what would be the return
that you would get, if the price kept changing at that same rate
for a whole year.

timescale you look at, but that's true for most other indicators, and
what you use really depends on the timescale that you are concerned
about. The advantage of the annualized ROI concept for gradient is
that, once you decide on the interval that you need to use, which
should be consistent with your trading or investment timeframe, you
then have an EQUAL basis of comparison for ALL your potential trades,
investments, etc, and even the interest (if any) that is paid on your
bank account. :-)
