Clearing cache, is it just deleting folders?

You can shut down the platform and delete the folder Documents -> NinjaTrader 8 -> db -> cache then restart.

What you're losing is the pre-built bars of each type - so for instance, if NinjaTrader combines 1-tick bars to make a Renko bar, it saves that, so it doesn't have to reload all the tick data every time you open a Renko chart - deleting the cache folder forces it to rebuild the bars. This sometimes helps, because sometimes what is saved in the cache is wrong so when it rebuilds them it has a fresh chance to get it right.

Hello MatthewLesko,

I don't believe there are folders in the web trader at web.ninjatrader.com.

Are you referring to the browser cache?

What is the issue you are experiencing?

[MatthewLesko]

Sometimes there will be slowness or order submission issues and lag closing. But when I proactively clear these folders, I have fewer issues.
So while this is not a direct correlation to solving a problem, it's more of a proactive measure I want to take, but also want to make sure it doesn't cause other problems.

Hello MatthewLesko,

I see this is no longer a question for the webtrader at web.ninjatrader.com and this is now a desktop inquiry.

Clearing the cache and historical data does not affect performance. Running scripts affect performance.

Below is a link to a forum post on performance.
