Playback issue

[snoussi]

Hello team, can you see the video attached? I'm trying to do playback, I'm in x500 x1000 speed but when the strategy enters into trade, I have the impression that it blocks and time does not move or moves too long while I am in x500 speed, it's a big waste of time because instead of doing backtests quickly, to do a day I need at least 2 hours, do you have a solution please? thank you for your help

Hello snoussi


Thank you for posting on the NinjaTrader forums.


I recommend to use the 'Go To' function if you like jump to a different date/time. Please right click in the Playback control window and select 'Go To'. Select the desired date and time and click OK.

You can experience slow and unresponsive behavior in NinjaTrader Desktop if you have multiple workspaces, charts, add-ons, indicators and other windows opened depending on market volatility as well. If market volatility increases, the same setup will need more PC resources.

Please check how many workspaces you have opened in total. You can view the workspaces you have opened at Control Center-->Workspaces. If a workspace has a green or grey icon in front, it indicates the workspace is opened. The green workspace shows on your monitors. The grey workspaces are opened in the background - you don't see its windows on your monitors, but they are active and take up CPU and RAM. Check if performance improves when you only have 1 workspace opened (one green workspace and no grey workspaces).


The 'Calculate' setting for indicators and strategies is important. If set to 'On each tick' or 'On price change', the indicator/strategy will be calculated on each incoming tick or each price change. During high volatility this can be very CPU intensive especially if the indicator/strategy makes complicated calculations. If you set it to 'On bar close', the indicator/strategy will only be calculated at the end of each price bar.

Thanks NinjaTrader_LuisH for your reply !

I have to test a strategy in real time via playback, so I need to have the results over the day, that's why the Go To function is not adequate in my case, here is the system information on my PC, I still have an I7, and I have allocated the maximum performance to the NT8 application, so I don't understand, especially since I only have 1 workspace that is open and I only use a chart and an instrument.


Thank you
