PushAds is a no no for this probably.
Influencer marketing? Like traders etc? They can do it themselves most likely they won't need you.
Mass DMs and Mass botting on X (popular trading platform) may work, but I know a lot of traders and none of them are actually using tradingview premium.
From what I know, and that is not THAT MUCH, majority of TradingView sales are actually tools that are using their chart tracking to implement in their own products.
When it comes to paid ads, maybe just use "best trading chart tool" or some keywords like that.
But all in all, I don't see this to be some ground breaking aff offer for you to spend time on it, since it's blackfriday I think you can find much better B2C affiliate offers to promote.
