It's been a while since I've been on quantopian and I'm relearning things so this is probably a no brainer,but I can't get the contract win dataset to work in my notebook (attached).
My attempt is just to filter down to the QTradableStocksUS that also have had a contract win over the time period (which I've defined as contract_win_amount > 0).
In doing so, I get the error "TypeError: zipline.pipeline.pipeline.init() expected a value of type zipline.pipeline.filters.filter.Filter or NoneType for argument 'screen', but got blaze.expr.arithmetic.Gt instead."
Anyone know what I'm doing wrong?
