# NinjaTrader RAM Drive
|
|
|
|
A guide to creating and using a RAM drive to speed up NinjaTrader.
|
|
|
|
This involves placing the NT database folder (where all the downloaded data resides) into RAM.
|
|
|
|
The one downside is that when you turn off your computer, that data is gone.
|
|
|
|
NT will automatically rebuild the database the next time it launches, though.
|
|
|
|
Still, make sure to save a backup of your database folder before attempting this, just in case.
|
|
|
|
To begin, download the following tools:
|
|
|
|
ImDisk Toolkit (for creating the RAM drive):
|
|
[https://sourceforge.net/projects/imdisk-toolkit/](https://sourceforge.net/projects/imdisk-toolkit/)
|
|
|
|
Link Shell Extension (for creating a symbolic link from the database folder on the RAM drive to the default NT directory):
|
|
[https://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html#download](https://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html#download)
|
|
|
|
First step is to create the RAM drive with ImDisk Toolkit.
|
|
|
|
Here's what it should look like. Just click OK.
|
|
|
|
|
|
|
|
I created a 20GB one in the screenshot, but that's because I had lots of RAM to spare.
|
|
|
|
At the time I'm writing this, the database folder on my machine is < 2GB, so you probably won't need anywhere near that much space.
|
|
|
|
Next, format the drive.
|
|
|
|
Just use the default settings:
|
|
|
|
|
|
|
|
In the end, you should see something like this:
|
|
|
|
|
|
|
|
Next, navigate to your NT directory.
|
|
|
|
It's in your Documents folder by default.
|
|
|
|
Example location:
|
|
|
|
```
|
|
C:\Users\<YOU>\Documents\NinjaTrader 8
|
|
```
|
|
|
|
Inside of that folder, there is a folder named db.
|
|
|
|
Rename it so that it serves as a backup (e.g., "db-backup") .
|
|
|
|
Now create the symbolic link so that any data written to the database goes to the RAM drive instead:
|
|
|
|
Create a folder named "db" on the RAM drive (D:\ in the above example).
|
|
|
|
If Link Shell Extension is installed, right click on that folder and select "Pick Link Source":
|
|
|
|
|
|
|
|
Then navigate back to your NT directory, right click and select "Drop As..." -> "Symbolic Link":
|
|
|
|
|
|
|
|
Now when NT is launched, it should place all the downloaded data on the RAM drive instead of the SSD / HDD.
