That tool will draw a channel that matches what the drawing tool will draw if it's not calculating on bar close. If it is calculating on bar close I can't get the drawing tool to match it..

This will be addressed in ver 1170. To make the tool and the study match: * Calc On Close = No - The study will use the last N bar values to calculate the channel, and it is changing with updates to the bar. Draw the tool on the same N bars. The tool does not recalculate with bar updates, so it is a snapshot in time, so may not continue to match. * Calc On Close = Yes - The study will use the prior N bar values (offset of one bar because final bar is not included) to calculate the channel. Draw the tool on the same N bars. Note, be sure the option Chart Settings >> Advanced Settings >> Adjust Tool Values to Tick Size is disabled. If it is enabled, the channel could be slightly offset.

line 1115 in Studies5 has to have the "-1" term removed.

In the latest version the calculations should be correct. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I started running the latest version. The Endchannel study seems to be perfect but the linreg tool seems to have changed, I cannot get it to match the Endchannel. I checked and rechecked the settings of each, same input data, same setting for standard deviations, neither the slope nor the channel width match.

The function for LinearRegression... I don't understand what exactly it does... can it be used to draw the typical linear regression line? It would be nice to have a function that returned all the values for a linear regression line or returned the variables for the ax +b formula.

Ver 1174... The Linreg drawing tool draws the same no matter the choice for "calc based on" in the Tool Config

We have verified that the linear regression tool works correctly, and uses the "Calc Based On" config properly.
