Anyone think it is possible to day trade stocks (not futures and close out positions by end of day) with buying power in excess of $20 million? It can be frustrating to close out of 20,000+ share positions at end of day without slippage. So unless you are trading S&P100 names where there isn't much money to be made, I would think it would be a great liquidity hurdle to day trade stocks with greater than $15 or $20 million buying power. The good day trading stocks are usually under $10 billion market cap and often do not accomadate 30,000 share positions. Some do, but not day in day out. So therefore I assume that virtually nobody is daytrading with $20 and $30 million buying power in stocks. Am I wrong? So if you have $30 million+ with which to day trade, you won't be day trading stocks. I guess currencies or futures would be your only bet. I guess thats why hedge funds are all in Spyders and futures.
