How calculate a simple Angle ?

Take a look at this post for a possible solution : https://www.mql5.com/en/forum/173056/page3
Hi ,
I would like to get the angle value bewteen last timeframe of J1 to current J1 ,the angle value should be from 90 to -90.

Any help is very appreciate!!
ThanksThank you for your quick response, mladen.
To be honest I am not too familiar with MT4 coding, I just want to someone who can help me revise or append into my existence code.

Unfortunately the code you attached is simply not going to work so it is not just a matter of appending into existing code, and from the code itself it is not visible what is the exact "intention" of the code. What is exactly what you want to calculate with that code?

Sorry, mladen !
I think missed some code.
I just re-paste the code as following:
#property indicator_separate_window
#property indicator_buffers 5
#property indicator_color1 Green
#property indicator_color2 Yellow
#property indicator_color3 Blue
#property indicator_color4 Chocolate
#property indicator_color5 Red

how to collect angle degree for yellow arrow in every timeframe ?
zhouyuwei
As you know, on time series we have 2 axes with 2 different types of values. on Y axes we have price or some value and on X axes we have time. The two values are not compatible and because of that you can calculate the angle. When the indicators values are "on chart" you can approximate time part with ATR (as it is done with angle of average) but with an indicator in a separate window you need to find out some other way of approximating X axis values
Or use simply a slope (current value - previous value = slope).

Yes， i just want to using simply a slope (current value - previous value) , but how to add them in my code ?
I suppose you want a slope on the "final" value, in which case you can do something like this (just the final loop changed a bit) :
{
J1[m]=iMAOnArray(J,0,N1,0,MODE_EMA,m);
double slope = J1[m]-J1[m+1];
}
And you can do whatever you wish with the value stored in the slope variable in this case (it is containing the slope between the two consecutive values of J buffer)

Thank you so much, man ! 
i figured out that value finally ！
