Trading contest: is it halal?

There’s a skill-based trading competition by TradingView where you can win cash prizes up to $10,000, but it’s all paper trading—no real money involved. You need a paid TradingView plan to join, but there’s no entry fee. If you’re in the top 5, you win cash, if you’re not but your account ends in profit, you get a coupon for a free month of the paid plan. Is it halal to participate?
