In youtube your video has a link to a website, and the website a link to a 50$ or more donation only for this indicator. In essence, you masking a business here without paying Baron his share.
Not a business at all. If I were running an indicator business, I would have no time to trade. Donations get you an entire year's worth of indicators. Or you can download some of my indicators for free. The MT4 MOTHERLODES are not hard to find.
