How get angle or slope of trendline?

Is there a way to use time stamps like points or integers so I can use them in simple math calculations?

In mt4  Draw trendline by angle  tool do it

the slope is in point per Bar

   Angle can't be done.
   • There is no angle from 2 anchor points. An angle requires distance divided by distance; a unitless number. A chart has price/time. What is the angle of going 30 miles in 45 minutes? Meaningless!

   • You can get the slope from a trendline. Delta price / delta time. Changing the axes scales changes the apparent angle, the slope is constant. Angle is meaningless.

   • You can create a angled line using one point and setting the angle (Object Properties - Objects Constants - Standard Constants, Enumerations and Structures - MQL4 Reference.) The line is drawn that angle in pixels. Changing the axes scales does NOT change the angle (and thus is meaningless.)

   • If you insist, take the two price/time coordinates, convert them to pixel coordinates and then to apparent angle with arctan.

2. iBarShift

   
   

I have get my values from Y axis values like this Low[L1] /(Low[L2]/High[H1] /High[H2]

llhypl = MathSqrt(MathPow((iBarShift(NULL,0,Time[Low[L1]])- ( iBarShift(NULL, 0, Time[Low[L2]]))),2)+ MathPow(((Low[L1]-Low[L2])*100000),2));

So i get an error when I try to get  values into the iBarShift function.

Time[Low[L1]]
iBarShift(NULL, 0, Time[Low[L2]]

1. Babel. If L1 is an index, Low[L1] is a price of bar L1. What is the time of a price? Meaningless.

2. If you meant Time[L2], the shift of Time[L2] is L2. Babel.
