No actually newbies are not my target, i could sell my product for 50usd/month and target newbies (retail traders mostly), there are millions of them, new comers every month, but i'm not interested, my ideal clients are professional traders, with 5-10yrs experience.
Those who trade for a living have already figured out how to make money. Unless you yourself can show 2-3 years of actual trading with using the indicator, managers are not going to think twice of getting. Plus, there are many of us who can look at your indicator and eventually break it or come close to doing that, you may not realize it, but people where doing much of this in the 1990s, I, myself have over 1,000 indicators and there is just so much you can do with numbers, but everyone thinks theirs is special. If it was that special, you would be trading the heck out of it, but I am guessing you don't have funds to open an account and this is a way to do it. I doubt there are millions of traders, last I read was 60k new day traders a year based on opening accounts USA and that was several years ago, so volume is down and guessing this number is less, maybe in China there are many more. Sell it there.
