QTradableStocksUS not being noted by IDE backtest
Ben
posted Oct 24, 2018

Hello there

I have a backtest for an algo in which I'm trying to get towards the point of competition submission.

One of the outstanding problems is that, despite filtering for the QtradableStocksUS universe, Quantopian is telling me i'm not.

Here is the code I user to set the universe. 

from quantopian.pipeline.data.builtin import USEquityPricing  
from quantopian.pipeline.filters import QTradableStocksUS

Followed by

is_tradable = QTradableStocksUS()  
longs = arrows_up & arrows_up1 & buy_spike_struck & falling_lows &  lower_band_pen & is_tradable

What am I doing wrong?

Thanks in advance!

Now for the last few back tests it IS saying the algo is using the QtradablestocksUS universe. The code has not been changed. Anybody else experienced this? Seems buggy?

Found that this has been asked before, and solved!
