As a genberal topic discussing relative moves of stock prices and trend
strengths
I prefer to use price unit per time period and through my investigation of
many charts I have found that this "slope" varies between different stocks,
and within a stock for the different price ranges. What might be normal
slope for one stock could be either fast or slow for another. The strength
of the move for a stock can also be dependant on the overall price
behaviour. An example would be that if there has been a considerable
accumulation pattern the initial move, when it does happen, will often be
fast and short lived. Then as the "traders" move out the investors will make
the moves and pace will slow down. These moves can be either direction.
I have set up a small line on my charts to give me what could be termed the
"average slope" for that stock in recent times. I can then place the gann
fan over this using the line as the 100% (1:1 line) and move the fan to the
recent turning point to provide a visual aid on the progression of the move.
This is in its own indicator chart panel for this purpose.
Cheers,
Graham

Subject: [amibroker] Re: Trendline with Degree output
Personally, I find the angle output very useful because it's an easy
to understand indicator of trend strength regardless of the time
frame. For example, a 60 degree angle of a trendline (strong trend)
on a 4-hour chart can look almost flat on a 1-min chart (zoomed).
The fact that the angle remains the same, makes it easy when looking
across different time periods.
In addition, however, can't an angle measure be useful with MAs as a
measure of trend strength or consolidation? Let's say a 20-period
MA is rising in a stairstep fashion. The average degree of that
rise (from an imaginary horizontal zero line) over 10-, 20-, or 50
periods would show how strong the trend is. Similarly, when in
consolidation an MA may bounce around the flatline in a zigzag
fashion over x periods. A low average degree (of deviation from
zero) would indicate consolidation. Obviously, using angles with
MAs is time-frame dependent.
