on topic: yet the "laws" still says "tend to"...which means there is a more than 50% chance. off topic: spend some time with a backtester. you'll find that as you tighten your stop loss, your winning % drops so in the end you break even. thats why everyone is obsessed with looking for an "edge". "edge" = when stop loss equals take profit, chance is above 50%. no offence but thats basic statistics/probability. the % chance doesn't really matter when viewed independently from the payoff.
