Can you afford to hire 10 (or several hundred, like Goldman Sachs) math / CompSci PhDs from the world's top universities, and build a 5,000 CPU Linux cluster to run the simulations / analyses these mathematicians propose?
That's who you're competing against, not the guy with a windows machine running TA charts (who thinks he's uber-sophisticated because he has 3 or 4 monitors hooked to the machine) who will probably never even break even on his time for "TA education" & computers and the fees on the short term trading churn.
try it,
AND track your investment in it (to make sure you don't fool yourself)
track:
cost and time for education
cost and time for your analysis
cost and time to set up stops / execute your trades
costs for slippage (NOT ONE of the trading systems I've seen account for bid/ask[0] or missed buy-in or sell-out[1])
cost for data feeds
cost for trades
(remember that you are paying ALL of these costs using after-tax income)
and at the end of the day, figure out the return you need to make on your trades to come out ahead on all that expense. I bet you'll need to earn 30 ro 50%, minimum, and that's BEFORE you make one thin dime of profit.
[0] I looked at a ton of systems in the late 80s / early 90s and NOT ONE systems seller ever analyzed their "profit" correctly. All systems lost money if you accounted for all the costs. Most never included this slippage, or even trading costs or tax in their calculations. For the longest time, US municipal funds were the ONLY money making "systems" investment, if you accounted for all the costs, because they were tax-advantaged.
[1] And all the systems assumed you sold at their trigger price - you never missed a fill at a fast-moving target price.
