Yep, or rather, predicting where the market will not go to avoid the price moving against my quote. My impression was that HFT is all about being fast, as opposed to smart, since you can't make complex predictions on nanosecond scales. Complex models don't fit on an FPGA. So couldn't you get an edge by being just a little bit smarter with predictions but slower and quoting wider spreads? And just to be clear, I'm not talking about minutes here, but maybe milliseconds to seconds, which I think wouldn't be considered HFT today?
