Description

MultiCharts .NET64 Version 9.1 Release (Build 12589)
The LinearRegCustom method gives incorrect results for lookback periods greater than 1024. I wrote a simple signal (attached) to illustrate the issue:
In my example, a regression line with lookbackPeriod = 1024 minute bars gives a strong negative slope. Adding just one minute to the lookbackPeriod flips the regression to a positive slope. This is clearly mathematically impossible.
Please see the attached screen print: it is obvious that the green 1024 line is corrent while the red 1025 line is completely incorrect.

Steps to reproduce this issue

Run my attached signal. The test is done on a EUR/USD minute chart.
