Jack,
The actual fact is, competing with the large institutional computers, the only way to be profitable is to let the computer do it. I am now up to running 5 fully automated Cooltrade automated traders (on 5 separate computers, trading 5 different brokerage accounts) and cleaning up.
CoolTrade continuously releases new strategies for free. I test in live-simulator mode for a few weeks and see the profits, then I open another account. The fact is Jack, once you go automated, you will never trade manually again.
They only charge $39 a month for the live data feed and the software is free. I love the fact that my computers are trading the market all day while I go about my life. I remember all those years when I used to trade manually in front of a computer all day. Never again!!
