Regression Channel chart bug

[Camdo]

On a multi-instrument chart, the regression channel indicator turns into a verticle line after about 20 minutes of live data feed.
Using: NT 7.0.0.21

setup:
BGU 1 minute candlesticks, 50 days
add regression channel (35,3)
add SPY 10 minute in separate pane
add stochastic (SPY 10)(3,14,3) in separate pane.
wait 20 minutes
regression channel will be a verticle line.

auto scale true/false makes no difference.
remove SPY data series and the regression channel will pop back into proper shape.

Camdo,

This can be the case as you use a non-equidistant chart when you add a secondary series. The secondary series forces the x-axis to be scaled based on time and not based on bars. The relationship of the regression channel's shape was linked to bars and when the chart is no longer on a bars basis, as data on one series gets added, but not in the other, things can start "moving". What you want to check is the anchor points and manually take a look as to where they should be plotted. Remember, the charts are now purely time based and anchor points do not necessarily lie on a bar.
