but what motivates the choice of action can be very complex... Try and
unfold that decision making process only from the result and it could
take you forever...
hi siddartha,
Regarding the above , I think you misunderstood .
Stockmarket has only very few actions ,
One is buy , next sell and finally stay away (no position ) .
So it makes it very difficult to find a solution since there are very few alternatives .
..
Using patterns or statistic indicators etc etc one or many in a strategy and then
using postion size and playing something like blackjack in the stockmarket where
you use the statistic indicator ,pattern etc etc as some basic strategy
and then card counting for the position size where you roll your money at favourable odds and keep away at less than favourable odds is generally what most are expected to do to make good HUGE Money .
.... My last so many years experince in stockmarkets after having tested ,backtested and traded many indicators ,patterns etc etc in strategies as mentioned in many books last so many years and i finally came to the conclusion that :
NOTE : the word HUGE as you have written ,,
huge money consistently can only be made by keeping it short and simple .
Have a strategy and use different TACTICS to trade that strategy depending on market
conditions .
Most indicators dont work all the time but most strategies do along with the tactics .
............ Thats what i wanted to convey .
Complicated strategies etc are well i feel not really effective .
Trade stockmarkets using the BLACKJACK method .Basic strategy + Cardcounting to
roll your money . ITS SAME AS strategy plus tactics .
You must be knowing that blackjack is the only casino game that can be beaten
consistently .

-- Warm Regards; `````` Natasha !!! Capitalism is a law established by God. Its foundation is in the 9th Commandment, "Thou shalt not covet."
"We are fast approaching the stage of the ultimate inversion: the stage where the government is free to do anything it pleases, while the citizens may act only by permission; which is the stage of the darkest periods of human history, the stage of rule by brute force."
“When you see that trading is done, not by consent, but by compulsion - when you see that in order to produce, you need to obtain permission from men who produce nothing – when you see money flowing to those who deal, not in goods, but in favors – when you see that men get richer by graft and pull than by work, and your laws don't protect you against them, but protect them against you – when you see corruption being rewarded and honesty becoming a self-sacrifice – you may know that your society is doomed.” ~ 1957 Ayn R. ~ Atlas Shrugged
