How to restrict bar data to only that for the current session

[mbesha]

I have noticed that there are times when even if the Days to Load setting in the Data Series of my MES chart is set to 0 (Load data based on: Days), the data loaded in the chart is that of 2 days or two sessions to be precise. I have tried different ways to restrict the bar data to only that of the current session but without avail. Is there a way to accomplish this?

Hi mbesha, thanks for your post.

For a chart, the data is loaded literally based on days. So if I made a chart with 1 day on it right now, exactly 24 hours worth of bars will be printed to the chart. In a script, one could detect the beginning bar of a session using FirstBarOfSession, or in NinjaTrader 8 use a Session Iterator to partition data by session.

For visual confirmation of session begin/end you can set a unique color for the Session Break Line in the DataSeries menu.

Please let me know if you have any further questions.

Hi ChrisL. Does that mean that a chart will always have a minimum of 24 hours worth of bars? Is it possible to display less than that? I am aware of the ways of detecting the start of a session but I am concerned in the chart data on display.

Hello mbesha,

Thanks for your post.

Another option would be to change the data series parameter "Load data based on" from "days" to "bars" and then specify the number of historical bars you want to see the chart start with. Please note that as new bars come in they will add to (the count of) initial bars to load for period that you are connected to real time data. When you restart Ninjatrader, the chart would then again only load the number of bars specified.
