LineBreak bars do not load correctly in real time

[samish18]

When running a strategy live vs in a backtest, LineBreak bars load differently. I have gotten more or fewer breaks in the live environment and then when I pull up a chart ~12 hours later, the bars are corrected

Hello samish18,

LineBreak bars are like renko bars and change the open.

This bar type (as well as renko bars) build different in backtest and cannot be used with TickReplay.

I would recommend instead testing using Playback with Market Replay data.

I am not referring to a changing open price, I am referring to a different number of bars altogether. I printed the time and indicator values of each bar for a live test and backtest - the first bars 9/25 were different (as in more breaks)

Hello samish18,

To confirm, you are no longer using LineBreak bars which form differently in backtest due to the nature of this bar type changing the open?

I am using LineBreakbars. I am well aware that the open of linebreak bars repaints. My issue is that, as shown in the previously attached files the bars load differently not just in opens, but in breaks. Please look at the first bars on 9/25 in the two files - on has far more frequent breaks than the other

Hello samish18,

LineBreak bars can form differently in backtest which can affect bars moving forward.

You could also right click the chart and Reload all historical data if you feel there are gaps in the data.
