study(title="Linear Regression Slope", shorttitle="LRS", overlay=true)

src = close[0]
len = input(defval=150, minval=1, title="Linear Regression Length")
lrc = linreg(src, len, 0)
plot(lrc, color = red, title = "Linear Regression Curve", style = line, linewidth = 2)

lrprev = linreg(close[1], len, 0)
slope = ((lrc - lrprev) / interval)

//Please if somebody have suggestions how show this better, let me know
codiff = slope

Nice Tool Emilio!
What determines the length of the arrows? Thanks.

Hi! I am sorry by delay, I saw now your message. I think the arrow length depends on the spread between high and low candle values, not 100% by very close
I am glad you like the tool, I am newbie in this on trading, I am learning on the fly these things.
Thanks!
