"The result from any trading strategy completely depends on your money management"... is wrong and is harmful thinking.
The big problem most traders have is they have a disadvantage (negative expectation) on their bets. More precisely, they have a disadvantage on the sum total of the money they put in action.
But yes.... poor money management, mostly over betting, can break a person who has an edge on their bets.
And yes... poor trade/ bet sizing can cause other problems as well.
The big winning trading firms, like Renaissance Technologies, devote serious and continued thought to looking for meaningfull edges.
For a cautionary tale involving over betting (poor money management) look at Long Term Capital.
unlike most you are intelligent but I disagree
the edge belongs to a trader himself/herself and not strategy or tactics
positive expectancy, negative expectancy are all just illusions --things "gurus" came up
money management is the only objective tool available to traders
Renaissance Technologies' competitive advantage is math PhDs and computer power they use
Long Term Capital's Meriweather traded like they did at Salomon Brothers
good bye wish you well
