Ain't no golden rule in my opinion, these are just made up rules that people just make up, golden rule or no golden rule people make money in trading and most of the people making up these rule are not making profits at all, the reason why I'm harsh on this certain people is because they are misleading beginners, they make forex trading to look like on hell of a big deal, forex is not hard, it's easy, just buy at the right time and exit, but y'all make up rules that don't add up, I've been a victim of this when I was starting out, I was made to believe that I need to be a genuis before I can have a chance, but I tell you it's mostly lies, anybody can learn how to trade and be profitable, just put in the work, your life will never be the same.
There was a guy on YouTube that plastered his channels with this bogus rules but he himself don't follow them, this is a problem we should fight as forex traders, we shouldn't allow other people to dictate to us how we ought to trade or a golden rule we must follow.
