Quote from jack hershey:
Money is being swept from other trading applications all stemming from the PEP paradigm and its HS and PM's. Roughly over time the SCT trading capacity is met and that stream is swept weeky into the PVT which grows to 12 streams and a 100,000 share per strean capaicty limit. Currently, the Universe for PVT is running in the neighborhood of 40 stocks. these are perilous times. This, about 25 million dollar limit is then swept into the SSR where unlimited capital may be applied on the slower fractal. PVT partial fills, at capacity, are about 20 going in and 30 coming out. thsi is corssover trading using partial fills.
