We're released a new build of the server today which has some good improvements for your debugging and backtesting:

- Code errors in the Initialize() function will now be properly reported to console
- Code errors in custom data creation will also be reported to console
- Fixed memory leaks which allow us to increase the max number of symbols an algorithm can handle
- "Error()" function now highlights red in the console, "Debug()" is green and "Log()" goes to a text file
