SE_EQUITIES not adjusted for splits

Hi!

I'm trying to find some alpha in Swedish equities, but some stocks are not adjusted for splits.
Examples (SID): 1180082098818626, 1179029863485521

Is there a way I can work around it, or is it possible for quantopian for fix? :)

Hi Emil,

All pricing data is split adjusted as of the simulation date in a pipeline. Please see the explanation here for more information on what this means, and why we choose to adjust pricing data in this way. Note that the best way to build and test factors on Quantopian is to define them in a pipeline (as opposed to using pipeline to get the raw pricing data).

Let me know if this helps.

Jamie

Here is a notebook which may help visualize how pipeline adjusts for splits. As Jamie stated above, the prices and volumes are split adjusted but as of each simulation day. This is different from the get_pricing method, for instance, which makes adjustments as of the end date supplied to the method. Note however, that currently get_pricingonly works with US securities.
