Does everyone see the same tick bars or does it depend on when the chart starts?

I'm curious, if I open up a tick chart does NT start the current bar with the current tick and then continue until n ticks are received which completes the bar?

if I'm using market replay, and go to a few seconds before/after the starting point from above, will I get different bars? Or will I get the same bar?

With time based bars it's clear how this works, everyone sees the same bar. But for tick charts it's not clear if everyone sees the same bars or not.

I ask this question because when running my strategy against market replay, if I start at the beginning of the data for the day then the strategy & chart seem to be in sync. However if I start from a random time during the day, the strategy seems to be out of sync with the chart. I imagine the chart is starting from the beginning of the day and the strategy is starting with the first tick received once it's started?

It will very greatly .. even on minute charts.
Do some searching .. it's been discussed a few times, and is not specific to NT.. all charting programs will vary, depending on the feed used, time of day, internet or feed latency etc.

I realize that it could different with minute charts, but the difference should be slightly.

If one starts a tick chart at say 9:30:00 and another person starts a tick chart at 9:30:30 using the same bar size, it would seem to me that the two charts could be totally different, even if they're using the same datafeed.

The only post I found about this (http://www.ninjatrader-support2.com/...ne+tick+charts) didn't really answer my question.

I compared my charts with a friends and the answer is that even using zen-fire, the charts can be totally different. It all depends on when you start the chart. For example my ticks remaining were totally different than my friends. so we had different bar formations, etc. Very interesting.

Tick charts for sure are influenced by when the first tick starts. That is the starting point for the chart. If you decide to start your chart at 9:30:30 the running counter starts at that time. It doesn't go back to 9:30 and assumes x amounts of ticks.
