The historical datas are so different between IDE and Research that the backtesting result is also quite different.

I've read the discussion here:
https://www.quantopian.com/posts/research-updates-get-pricing-and-jupyter-notebook-upgrade

It tells:"This means that get_pricing now uses the same data source as Pipeline and the backtester. It also means that the data loaded by get_pricing is point-in-time split- and dividend-adjusted...."

I have built a simple example both with IDE and the notebook research. I find the price chart are quite different. And the backtesting result are also quite different.

Fron the attached backtesting and the notebook, one can tell the difference.

Here is the notebook. See the difference by chart and the sharpe ratio.
