Yes, the victory of the trading may be unexpected but I think the trade is never like gambling. I would always say every human being should change the thought. Those who think trade is often at risk of often, because the gamble is as it is. If an expert wants his trade success and I can say that if you have 95% confidence, it must be successful. Because trader requires a lot of experience, which is only within an Expert Trader. Although using more money increases the risk of each trade. That is why you should be trade with your own limitations without greed, it can avoid the risk. And a successful trader has many good strategies that he can use and a strategy will not always work, so the strategy should be changed over time.
