You’ll be happy to know that today’s release squashed a particularly troublesome EMA initialization bug. This is welcome news for those who use either the Vervoort Crossover or Heikin-Ashi Candlestick Oscillator as these use triple exponential moving averages and were negatively impacted by the bug. Thanks to the Thinkorswim team for hunting these down.

Something apparently happened on the platform (without a build number increment) because the discrepancy that crept in between strats and studies disappeared too. (strats were resolving the same crossover test one bar late.)
What studies are applied to the screenshot besides Volume Profile and HA?
Chris,
There is a Vervoort Crossover and an experimental Pesavento Lines study I am working on.

i am a paid up member. where do I find the new version?
Doug,
The bug was in TOS, not my code, and should have been corrected with build 1577.
Eric
how do i know if I’ve got the 1577 build… my code says “# Last Update 30 JUN 2009″
Doug,
Again, it is not my code with the bug (You are reading the date off of my code). The thinkorswim program itself had a bug and the new build has fixed it. Your build number is listed on the top of your TOS window.
