angle of indicaor

[stephenszpak]

I've posted about this before (sorry). I'm trying
to determine the angle in degrees of an indicator.
Then to color code the price bars according to
3 or 5 different angles.

This is just the basic indicator. Values not important now.

Plot0.Set(SMA(VMA(Close, 4,2),3)[0]);

I *think* it applies a 3 period SMA onto a 4 period
VMA with a volatility of 2?

I'm going to look here:

and here some more. If I find anything that I can comprehend
I will re-post:

(I did try to download MaSlopeBox last week several times. I
couldn't get it to go where it should, or work. That was most likely
my fault.)

The slope thread you linked to is the most conclusive thread on this forum about slope calculations. If I remember correctly maybe in the earlier pages there were equations being thrown around. You may want to concentrate your efforts there.

The line:

RadToDegrees*(Math.Atan etc. etc. etc.

got my attention (by dwalls). Also

(System.Math.Atan(Slope(SMA(5),CurrentBar-1,CurrentBar))*180/Math.PI).ToString()

by you. Not sure what this is all about however or how to apply it.

These are basically mathematical formulas that you can set variables or set plot values to.

Where do I find info on Math.Atan if you think I really need it?
Where do I find info on 180/Math.PI if you think I really need it?

I'm not sure what I even need to do this problem regarding what
code is necessary, but the two above at least might be needed.

Thanks,

The easiest way to get the slope of an indicator is to create a strategy using the wizard and use the MASlopePlot indicator created by Gumphrie and set the InputSeries as whatever indicator you want and set the 'Plot on Chart' parameter to true. You can leave the 'Do the Following' section blank if you wish.

If I'm not mistaken, NT7 will allow indicator on indicator so this cumbersome process will be seamless in the future...

Thanks. I actually just did it! I didn't know I had to:

File | Utilities | Import NinjaScript

I thought extracting it was enough. I will get back if I can or can not
do something with this today.

Ok, the VMA in NT requires 2 inputs. I don't see that available in
MASlopePlot. I also will have to do post smoothing of the indicator
and possibly pre smoothing of the data for the indicator. Someone
had this basic question a while back. I'll contact him, but of course
you can continue here if you really want.

I contributed a little bit to this indicator, so hopefully I can shed some light on it....

Although the VMA requires 2 parameters, by default they are the same value, so the 'Period' value is also used for the volatility period.

case SlopePlotAverageType.VMA:
                    maSeries.Set(VMA(Period, Period)[0]);
                    break;

Similarly, KAMA also has more than one parameter, but I simply used the default ratio between the parameter values.

case SlopePlotAverageType.KAMA:
                    maSeries.Set(KAMA(Period / 5,Period, Period * 3)[0]);
                    break;

The reason for this was to try to keep the indicator as simple as possible and not have to have a bunch of parameters that only apply to a single moving average type.

I think I made a couple tweaks to this indicator and haven't reposted it. When I do I'll probably add support for pre-smoothing because I think its a good idea.
