Here's a very fast linear regression slope functions I derived from
something M. Simms (also on this list) wrote:

I doubt you'll find one any faster.  Once you have the slope, the
y-intercept is easy: just plug one known data point (such as the
mean price and the position of the mean) into y=mx+b (where y=price,
m=slope, x=position [e.g. x bars ago]) and solve for b: b = y - mx.
