Replay volume bars dont match Simulation

[maxima]

I run a strat on Mirus connection today (on Sim account) and was recording it for replay at the same time.

Then I run the same strat with same parameters on Replay using the same data I recorded earlier...

Here is the print of random part of bars:

Sim
28/01 15:50:15 slope: -0.0005 MA: 1772.4986
28/01 15:50:18 slope: 0.0000 MA: 1772.4986
28/01 15:50:19 slope: 0.0058 MA: 1772.5044
28/01 15:50:20 slope: 0.0470 MA: 1772.5514

Replay

28/01 15:50:13 slope: -0.0058 MA: 1772.5532
28/01 15:50:18 slope: -0.0002 MA: 1772.5530
28/01 15:50:19 slope: 0.0045 MA: 1772.5575
28/01 15:50:20 slope: 0.0437 MA: 1772.6012

Bars and indicators on them are a bit different... What it could be?

I set Calculate on Bar Close = true in both cases.

maxima,

Perhaps you are using different starting points for your charts? Check session templates and lookback periods. Please ensure you are comparing same historical data sets too.

there is 256 all the time.. I dont touch things I dont understand.

The data for replay was made during the simulation I run the first strat.. So it has to be identical...

Does NT cut volume/tick/range bars on midnight? How can I manage the starting point?

Depends on the historical data that is loaded up when you start the replay. Indicators calculate on the full set of data including the stuff loaded prior to the replay date. That data needs to be exactly the same. No way to know without printing full details of them from both sim run and replay run and comparing.

NT does restart those bar types on session end as defined by the session template. You can change the starting point by changing the session template definitions.

will do thank you
