First, whenever I see someone say that this tool or that tool doesn't work (especially the main ones like MAs or TLs or S/R etc.) I'm definitely sure they are not an experienced traders (2 or 3 years are considered inexperienced). No offence.
Second, I can understand that this path is so hard that some people in the first steps seek motivation. They want to see some evidence to appease them and make them hell-bent but unfortunately most of the time, if not all the time, the only people willing to show such a thing are tricksters and the real profitable traders don't have any motivation to do so. Why should anybody want and like to reveal their records?? If in a few cases someone wants to show their records to attract investment, they definitely won't do that on forums like FF and just for motivating some new traders. There might be a few ways to be assured something ( a tool, some kind of MM, various ways of analysis etc.) is profitable but the best one is to pay the cost by working on it and become an expert at it. Shortcuts don't work in this field so it's better not to look for evidence or distractions like them and home in on your goal. I spent the first 2 years of my trading carrier on BS like that and some stupid and wrong thoughts were along with me with a few years after that but something happened that I cleared my mind from all those BS and that was the place where I met some results that I couldn't imagine them before, never ever.
Successful people never listen to failures and the failures can't believe and imagine what the successful people say, do, feel and think.
