Beginning after market close today (3pm CST, Dec 15) and through Friday we’ll be using a new version of our server software.

You should not notice any significant differences. Rolling Tests will run slower (2x to 3x slower) during this testing period.

We apologize for any inconvenience.

I’m getting weird results. I’ll run the same backtest twice on a screener and get two different results.

yuvaltaylor,

can you give us some details (which screen, what period)?

thanks

Well, it doesn’t seem to be happening anymore. It was a screener called “testing 2” and the period was the last 15 years.

6

The universes seems to be broken - we’re only getting 100 stocks where we usually get thousands.

7

Same problem…is this being worked on almost my with the Compustat problem?

8

which universes?

9

11

Am only seeing 100 stocks in rank universe

12

Sorry, we’re having problems replicating this. Are you seeing this problem in rank output or with a universe that’s using ranking?

Actually, can you post a link to the system where you’re seeing the problem?

13

I have an ETF universe that is broken:

Strange, the Sim that uses it works but the universe shows no constituents:

Thanks for raising the issue. I will look into it and patch it ASAP.

15

works now. thank you.

16

I do not know if what I am going to say is pertinent to this issue, but now I have just re run some of my sim, and some of them have their performance dropped not a little…I just re run without changing anything.
Is this happening to anyone of you?
