Minor website changes today
Dan Dunn
posted Jul 31, 2013

Today we made a few changes that you might like to know about. The first one is the biggest change; I wanted to point out the change in behavior of the IDE.

  • When you're editing code in the IDE, we added a number of typing scenarios where the auto-complete and tooltips appear. In particular, if you're backspacing through an already-typed command, the tooltip appears in more situations. That means if you start with sid(24) and you backspace to sid(, you will get the sid autocomplete - before this change, you had to also delete the (.
  • Minor improvements to the help documentation
  • When running backtests in the IDE, we had a bug where logs weren't always cleared, and it would get confusing. That is fixed.
  • There is a much, much better error if you try to do papertrading or live trading with a warmup period that is too long.
  • Reading the forums should be faster because of a change in caching of forum threads.

As always, feedback is welcome.

Just out curiousity - how long is too long for a warmup period on a paper trade?

You can't warm up paper trading to before 3/1/13. That's about 110 trading days, and it goes up by 1 every day =)

Soon, we're going to add another year of data, so we'll support 360+ trading days of warmup for paper trading. I'm hopeful we'll add that data later this month, and I will certainly announce that here.
