The screen I used was:

Define {WER}
step0: [Security Type; lag=1 days] == 0,10,11,12,18,30,31,48,71,72
step1: [Mkt Days Since Security Opened; lag=1 days] >= 63
step2: [% Rank (tie-averaged) by [Average dollar-volume over 63 days; lag=1 days] (Asc) at step2] >= 50
step3: [WER Rank In List; lag=1 days] != null; Cash When None
Holding period = 21 mkt days
Frictional loss of 0.4% applied to all sales (closing long/opening short)
Equally weight new positions, fully rebalancing all liquid positions to equal weight every 1 holding periods
All trades at market close.
