 Like NinjaTrader, ProTrader builds all files from repository (directory with source codes) into one combined dll. So you will need to copy your scripts before compilation. To add Ninja Script into ProTrader Desktop, follow next steps:

1. Copy your script to Ninja Repository. Find Repository location in General Settings.
2. Open any script from Repository
3. Right-click in the Editor and choose Compile Module. ProTrader Desktop will automatically compile all Ninja scripts available in Repository.
4. Once compiled trading strategy or indicator becomes available in ProTrader Desktop

Note: If script uses additinal labraries (i.e. dll), you will need to copy them to  ProTrader's installation directory/include/  before compiling
