What does that cryptic message mean? It points me to Q2 migration page that has no mention of "current_securities" function or "security_lists" at all. What is "DT" mentioned at the error?
Context: In the past I could check that security is not in leveraged list by the following simple if, this is what triggered the error:
if asset not in security_lists.leveraged_etf_list:
What is the correct form from now on?
Just got the same warning today on my live algo for precisely the same line. Can someone shed light on this?
Here's the announcement of the change: https://www.quantopian.com/posts/new-asset-restrictions-api-deprecation-of-set-do-not-order-list
Pointing you to the Q2 migration page doesn't sound right, though. That sounds like a bug.

The equivalent to if asset not in security_lists.leveraged_etf_list: is now if asset not in security_lists.leveraged_etf_list.current_securities(dt): where dt is the current time get_datetime().
However, if the goal is to avoid trading leveraged ETFs, the better way to do this is to call set_asset_restrictions(security_lists.restrict_leveraged_etfs) in initialize and then replace the above code with if data.can_trade(asset):. For any asset that is restricted using set_asset_restrictions, can_trade will return False
