I'm not sure if I've expressed myself correctly. Generally speaking, regardless of the quality of the product or whether it's paid or not, the revenue curve is the basic presentation. You don't need to get caught up in self-considering whether to present a "perfect" or "imperfect" product. A normal revenue curve is necessary.
After seeing the profit curve, I didn't quite understand it. You can see how your product is plummeting. Honestly, if you put this curve up in the first place, almost no one will look at it anymore. This makes me need to ask you " Very bad? " I expect it to be a problem with my own setup rather than a product problem.
Similarly, a very basic fact remains: you can't expect users to develop interest in your other products after seeing a terrible product that has experienced a "sharp decline" in popularity. Whether it's "reputation" or "brand," an immature product will ruin its reputation. MT5 already has a demo version; it doesn't need to promote itself through a free product.

I understand your perspective on branding and visual presentation. However, in professional algorithmic trading, a revenue curve is merely a mathematical output of specific input parameters—it is a mirror reflecting the setup, not the core logic of the EA.When you see a 'sharp decline,' it does not indicate a flaw in the product's architecture, but rather that the settings applied were mismatched with the market conditions. A sophisticated weapon in the hands of an untrained soldier will not yield victory. As a developer, I build the engine; the performance depends heavily on the driver. I encourage you to look deeper into the parameters and mechanics rather than judging the machinery based on a suboptimal configuration.
