As majority of traders in the forex market are losers so its quite clear that majority trade without any proper system or mindset. So, yes we can say that there is a greater percentage of traders trading in gambling style.
As a new trader no one knows how much risk he should take however demo trading can help to define right risk . If you are skilled trader even then too 30% risk is much for you . Try to remain at safe end how much you are using in trading . not exceed the limit what you feel difficult to manage.
I even cannot imagine how is it possible not to loose at all. Of course knowledge and skills give more chance to have success, but in any case we are not that people that make market. so it's gambling
yes, this is the main difficulty of trading, It really needs to be very attentive to every signal. Learning how to trade is a hard work, that's why not everyone atchieve success.In my opinion trading becomes gambling when you lose the touch with the market and understanding of its moving. When you panic and do not know what you are doing there is a lot like casino, red or black or if you lucky zero. If you keep strategy and final target in mind there is more than 30% that gambling will not be your story
