RE: Scalability for day-trading
Day trading can be very scalable, depending on your instrument of choice. Of course you don't day-trade penny stocks and expect that to be scalable. You pick the most liquid stock or ETFs.
For example, trading SKF, SPY, GS, AAPL.
You can trade 1000 shares of them or 10000 shares of them in the same minute. It won't impact the market a bit. These things... trading over 100,000 shares a minute, nobody gives a hoot to your 10k order. 10k of AAPL, $100 = 1 million dollar.
Or you can trade your 200 shares and be happy to catch the rides.
From making $100,000 a year to 10 million a year, you don't have to do things much differently. You just trade with more shares and scale-in and scale-out.
