I believe it is not 30% but 100%. But the important point is smart with system gambling or gambling purely by luck. Nothing in your life is not gambling.
Maybe yes, but I think not all trader will treat forex as gambling, still many trader using risk management and money management properly, but sometime lack discipline also as reason why any trader they violating rules tradingMajority of losing traders do trading in gambling style, this is why the rate of gambling in forex is very high. If you trade with proper money management then you can progress in forex market. But having a gambling mentality its not possible to become a consistent profit generator.
i think in someway it gambling .
Before put any order trader has to see market , analyze it well and see his capital how much he can use in trading. Much amount using in trading becomes dangerous as market moves. He should take proper risk ,higher risks tend to higher losses
