Issue 1: VMIN did a forward split and became untradable on Robinhood. My code checks for its tradability and it looks like it is not checking against robinhood to determine if it is or is not tradable using the service.
Issue 2: Because VMIN was untradable I've been manually doing trades with XIV when I see the rejected buy messages. However, on Friday it looks like the correct number of XIV shares are not being accurately updated for some reason like it has in the past. As a result, the live algo history show a drastic reduction in cash in my account while the number of XIV shares still show the amount prior to the purchase order. The end result is it appears I have an instantaneous loss. I've logged into Robinhood and confirmed that robinhood (the app) still shows the correct number of shares, so for whatever reason the number of shares in quantopian isn't updating.
