id like to apply to some hft firms later this year and am just wondering, would I still be able to trade my personal account? I've seen various restrictions imposed including no short sales, no short term trading (<30d), but these seem to apply mostly to big banks and HF's that trade the higher time frames. is it still the same for UHF firms? currently I trade a few strategies on the daily time frame, many are held <30 days (few days to a few weeks). they're pretty much all equity and sector ETFs (SPX, GLD, VXX, TLT, etc). given the infrastructure requirement for UHF firms and the totally different approach in strategy types (low latency arbitrages etc) whereas my trades are mostly directional buy 'n hold, it seems to me there would be little conflict of interest, but idk what the law states here. I don't run too many shorts so no worry there, but if I did want to could I replicate a short position via options and still be compliant? what about short ETFs? (short vol or short sector ETFs) what's your own experience here?
