Running from Command Line
SlimTrade can be run from the command line to cause debugging information, as well as errors, to be printed out. The easiest way to do this is with PowerShell.
Open the folder containing SlimTrade, shift + right click inside the folder (not on the program), and select "Run PowerShell window here".
When PowerShell opens, run the following command: javaw -jar "slimtrade.jar"
SlimTrade will then run normally, but if an error occurs it will be printed into the console. This functionality will be expanded later on to include more debugging information.
Powershell comes standard with Windows, but if for whatever reason you don't have access to it, here is an article explaining how to run a program using command prompt instead. Switch out the final command for the one above.
