The angle of a Moving Average

[ketoma21]

Is there an EFS file to calculate the angle of a Moving Average, if not then how would you write an EFS file to calculate the angle of a moving average, whether it’s 45deg, 60deg, etc….

Thank you

Hello Ketoma,

Here is a code example for working with angles. This information is from the EFS Help Center & Library.

Misc. Formulas

Calculate the angle (in degrees) of a slope:

//Assume a 30% slope (rise over run);
nSlope = 0.30;
nAngle = Math.atan( nSlope ) / ( Math.PI/180 );
nAngle now equals approx 16.67 Degrees.



Calculate the slope (in %) from an angle:

//Assume a 20-degree angle
nAngle = 20.0;
nSlope = Math.tan( nAngle * (Math.PI/180) );
nSlope now equals 0.3639 or a 36.39% slope.

Hello Jason

Thank you very much for the quick reply.

I saw this formula along time ago. The thing that I don’t understand how do you assume a 30% slope. How do you find the slope?

Assume a 30% slope (rise over run);

Thank you

Hello Ketoma,

Slope is simply rise over run or,

(yValue0 - yValue1) / (xValue0 - xValue1)

where the yValues are the values of your indicator on the y-axis and the xValues are x-axis values. You could use the bar index numbers for the xValues. Take the absolute value of the difference of the index values between the two bars in question.

Hi,
Here's a study i downloaded from the BB a few months ago.

I wonder if there is a script displaying a line connecting last point of MA to its point n bars ago, where "n" is an editable constant.

The attached efs draws a line from the current MA value to the MA's value "n" bars back (default is 0). In the image below for example the "n" lookback is set to 35 (which you can see in the Csr# in the Cursor Window)



All parameters of the MA and the "n" lookback period can be modified via Edit Studies. The "n" lookback value is a positive number even if it relates to negative bar index
