PC Running Sluggishly During Market Replay

[MoneyTrust]

When I replay marker data for backtesting, the charts tend to run very sluggishly. Every other part of the platform, mainly the control center, runs well but the chart is very slugging from the loading of the bars to the mouse movement. I've minimized the amount of scripts running/plug-ins running and the issue is still the same. Is there any troubleshooting that I can do to potentially resolve the matter?

Also, when backtesting and replaying market data, is it required that I select the exact contract month for the data that I'm using? For instance, I have a script that allows me to download multiple days of data at once but for the data to populate the chart, it has to be the exact same contract month instead of a continuous contract. Is there a way to correct this? Is there a way that I can replay data without having to specifically go back to the contract month? For example, I want to replay the CL contract and the current contract is the 03-24 contract. If I just want to replay the data without having to specifically choose the 03-24 contract and load continuous contract data, how do I do that?

Hello MoneyTrust,

Could it be you have workspaces opened in the background? Please go to Control Center-->Workspaces and make sure only 1 workspace is opened. If a workspace has a grey icon in front, it indicates the workspace is opened in the background. Check if the issue persists when there is only 1 workspace opened (and no workspaces opened in the background).

How much days do the start and end date cover? Does performance improve when you select a start and end date that only cover 3 days.

If you remove all indicators and add-ons from the charts, does the issue persist? If not, please add indicators and add-ons one by one in the charts. Check after adding each indicator/add-on if the sluggish behavior recurs.


Continuous contracts use the "##-##" expiry month in NinjaTrader Desktop. Unfortunately there is no Market Replay available to download for continuous contracts.
