I'd like to add a column that shows the actual slope angle for "slope of the close".

If possible, I'd also like to filter based on slope angle itself.

I haven't quite figured out how to do this yet. Could someone provide me with a link or some suggestions?

Thank you.

Found this and have been messing around with it.

Does anyone know how the "0.1709" is calculated, which presumably is based on the number of days (20)?

"
Here's a 20 day, for example:

Submit Fetcher[close above 5
volume above 1000000

set{originxy, open 20 days ago}
set{adjacent, originxy * 0.1709}
set{opposite_vector, close - originxy}
set{radians, opposite_vector / adjacent}
set{atanval, atan(radians)}
set{hcircle, 180 / 3.14159}
set{angledeg, atanval * hcircle}

add column angledeg

and chart-length is 6 months

Sort column 5 descending

Hi,

We see this request a fair bit in support. The trick with angles is that you'll need to assume a unit value for time that corresponds to price. Unfortunately this would not correspond to an actual chart of the data since the range of price used is based on the high/low of all indicators drawn.

The easiest way to illustrate this is the same slope for different time periods. Below is an example of the same 100 day slope drawn on 1 year & 6 month charts. You'll notice the slope of the first is around -35 degrees and the second around -23 degrees.



Also, using the formula mentioned above (adjusted for the close 100 days ago), the result is about -13 degrees.



Best regards,

Does this help?

set{x, slope of close}
/*find radians*/
set{y, atan(x)}
/*convert to degrees*/
set{z, y * 57.2957}
add column z
draw z
sort on column 5 descending

thanks graftonian and stockfetcher.

graftonian, one has to declare the actual time period of the slope of the close for that, as in "set{x, 150 day slope of close}"?


set{x, slope of close}
/*find radians*/
set{y, atan(x)}
/*convert to degrees*/
set{z, y * 57.2957}
add column z
draw z
sort on column 5 descending

That takes us back to what SF posted, same data, different time period, different slope. I feel like I've got one foot nailed to the floor
