i argued with my fellow trader that ,no-body ,even masters are 100% sure in every trade they do that it will highly favor them,,,because i understand that fully understanding market is like "knowing all the path of smoke in "brownian motion"
how traders be moving between pairs ,
trading is 80% pychology,
because even the best strategy ,creates more randomness ,and a good mat-phyic/pychological trader,,can trade whatsoever pair as long the pairs are real-legitmate mirror to what "trading" is.
