Pipeline on RSI, different RSI result compare to Finviz and other sites?

posted May 6, 2017

Hi,

To get familiar with Quantopian, my basic tasks is to implement some of the screens I have on finviz.com. As a simple example, I want to have a pipeline of stocks with
- market cap > 10b
- RSI under 30

I have other criteria that I have trouble with, like Revenue growth for the last 5 years etc, I will follow up with a different post.

Problem 1: However, when running the attached notebook, I found the RSI result on Quantopian is different from finviz and other sites. e.g, on today 2017-05-06, there is an entry of
mktcap rsi
Equity(3443 [HAL]) 3.870690e+10 25.293132

on finviz, the RSI is 33.61:

On finviz, the same screen returns 12 results while this one on quantopian return 83!!

on this site, it is RSI=33.46

So it seems quantopian's result is different from others?

Problem 2: How do I sort by symbol, rather than sid in the result?

Thanks for the help!

Kevin
