Maybe I'm the weird one, but I don't get how people trade patterns from fin-influencers with zero maths behind them

Genuine question, not trying to be a jerk about it.

I keep seeing people take a setup just because someone they follow posted a chart with a nice-looking pattern on it. And it works out sometimes, sure. But nobody ever seems to ask the obvious thing first: has this pattern actually worked before? Like how often, over how many occurrences, and did it still make money after the losers?

That part is almost never in the post. It's just a clean chart, an arrow, and a confident voice. And somehow that's enough for people to put real money on it.

Maybe I'm overthinking it. But for me a pattern with no numbers behind it is basically a nice drawing. I want the win rate, the sample size, and whether the edge survives once you subtract slippage and fees. If a setup can't clear that, I don't really care how clean the chart looks.

I'm not saying influencers are scamming anyone. Most probably believe their own stuff. I'm saying the format rewards a confident story way more than an honest track record, and those two are not the same thing.

So genuinely, am I missing something? Do you actually check whether the patterns you see have an edge before you trade them, or is it more of a "looks good, take it" thing? Curious how people here decide what to trust.
