How to define a strong trend ?

Quote from Xspurt:


Decades back I learned to watch the 45 degree angle. If PA is advancing faster than the 45 line then it is very strong. It's a simple rule of thumb that needs a lot of refinement but if you want a short answer... 45+ degrees.

Now as to how a trend is born and evolves - that's a different story.

You forgot to specify how your axes are calibrated

Measuring volatility over a period of time is the best way to catch the early part of a trend. As volatility drops the trends but you have to have a reference point, which is why you need to collect data and do some number crunching.

Use a Gann 1 x 1 line

From what I read, Gann gave no indication of how many price units constitute one price point / time period. So angle is still pretty much subjective

In geometry, you cannot mix different units of a triangle to arrive at an answer.

Geometric Triangles etc need to be measured distance x distance, or time x time, or weight x weight etc.
You can't mix distance x time or apples with oranges.

Gann was a con artist! Sleight of hand snake oil salesman in my opinion.

Then there is the issue of linear vs logarithmic units of price.
Either one will give you a difference in the trend line angles.

Its your business;

it costs you much in profits, comissions.

wisdom is profitable to direct

Yes, I believe EMA's are the most important indicators. I am still learning how to read it correctly.

I use the momentum indicators mainly for the entry, not the exit.
