Understanding the EOD

Hello
I read the page https://support.ninjatrader.com/s/article/Break-at-End-of-Day-EOD-NinjaTrader-Desktop?language=en_US but I don’t understand some things.
I use a Line Break chart based on minutes.
When I create the chart in EOD or “normal” mode, I see that it affects my indicators.
If I build my EOD chart using historical data, does it continue to be built in real time in EOD mode?
What is the impact on building a Line Break/minute chart, specifically? Does it use a starting point that will always be the same, the first tick of a new session? But for subsequent sessions, given that the chart is based on both price AND time, I don’t understand.

I hope I’ve been clear enough in my request, but I’ve discovered how easy this type of chart is to use, and I’d like to incorporate it into my decision-making process. My tests are giving very different results depending on whether I’m in EOD or not.

Thank you for your help.

EOD applies to historic and live data. Given that line break is a price action bar type, I would assume its behavior is the same as the range or point and figure bars as described in the document you linked (take a look at the example for 6 Range bars in that document) . Which means with EOD enabled, you get a hard reset at the end of a session and will start each new session with the first tick/bar. Whether that starting point is a tick or a bar depends on a couple of factors. To start a session with the first tick in historical mode you need to have tick replay enabled and have your indicator set to calculate OnEachTick. For live mode, you just need to be calculating OnEachTick. If you do not have tick replay or you are calculating OnBarClose the session start will be the first bar.

Also, (as noted in the line break documentation) make sure the indicators you use are able to handle this bar type correctly.
