There are advantages to making trades just to run up to total number of trades (lower commissions with some brokers, more data channels on IB, etc). So I'm thinking that my automated system can use excess cash when things are slow to make ultra-conservative trades that just make commissions. Ideally this system would jump in and out of positions fairly quickly to stay as liquid as possible. I don't have much experience with intraday strategies so any help would be appreciated. Any ideas? I trade only equities.
