I have 5 Charts in a sort of manual walk-forward test. All are linked = 1 and Scroll = Yes.
Charts are typically, 240m, 60m, 10m, 5m and 2m with Next Bar being advanced via the right H. Scroll Bar at the bottom of the 2 minute chart .... which is also the smaller timeframe.

Accounting for the composition of bars to timeframes the bodies 'current Close/Last Price' across my charts are inconsistent and in addition the Price presented in the Price Col. (Y-Axis) is also different for each chart which will be the source of the issue.

For example using [To Next Bar] or [To Next Time Increment 00:02:00:000] on the Bar Replay control with focus on the 2m Chart selected does nothing. Only the Bar Replay Speed has an impact.
Settings are [All Charts in Chartbook] and [Accurate Trading System Back Test Mode] and [Speed = 1] as I want to advance 1 bar at a time.
I've also tried using Standard reply and other permutations but the times are not synchronised across charts either and the [By Time hh:mm:ss:ms] / [To Next Bar] and [To Next Time Increment unit 00:02:00:000] along with the >> button has no impact.

Speed (n) Play however does advance the bars as expected.
