Calculating the Angle / Linear Regression of a line

  I’d like to be able to calculate the angle (linear regression?) of any line i.e. a moving average, a standard deviation

  For example.. if the angle of the Average[500] reaches X degrees positive/negative then buy/sell (means: don’t trade when it’s flat)

  What is the best way to calculate/code that?

  Regards

  Steve

  IMO it’s useless since angle degree depends of the height/width of your chart/computer screen. You’d better look at price percentage change over x periods, I think it’s more accurate 🙂

  Just browsing the forum as i noticed this post… as i’m using ema-trend as a trade filter, i’m happy to share a guite simple code:

   

  if tradeema[1]>tradeema and tradeema[2]>tradeema[1]then ematrend = -1 endif if tradeema[1]<tradeema and tradeema[2]< tradeema[1]then ematrend = 1 endif

  1 2 3 4 5 6 7

  if tradeema[1]>tradeema and tradeema[2]>tradeema[1]then ematrend = -1 endif   if tradeema[1]<tradeema and tradeema[2]< tradeema[1]then ematrend = 1 endif

   

  this simply compares if the tradeema rises or falls within the last 2 bars.

  you could also check if the difference of tradeema[2] & tradeema[1] if positive but smaller than the diff of tradeema[1] and tradeema -> which would mean it’s getting steeper.

  getting a angle value is useless imho as there’s the need for a absolute x & y scale. but based on the difference you could use a treshold value to check if the slope is steep enough…

  Brgds, Martin.
