Every trading app with a social side ends up with a leaderboard, and almost all of them sort by the same thing: how much the trader made. It's an obvious choice. It's also the wrong one if the point of the leaderboard is to help you decide who to copy.
The trader's profit isn't your profit
When you copy someone, you don't get their trades. You get trades that start after theirs, at whatever price is left by the time your transaction lands. In a deep market that gap is small. In a fresh Solana memecoin with a thin pool, it can be most of the move.
Worse, popularity makes it bigger. The more people copy a trader, the more buying pressure arrives right after each of their buys, and the better the price the trader gets when they sell. A trader can look brilliant on a classic leaderboard precisely because their followers are paying for it.
So we measure the followers instead
DYOR ranks traders by median copier P&L: take everyone who copied a trader, line up their results on closed positions after fees, and pick the one in the middle. Half of copiers did better, half did worse. Unlike an average, one lucky whale can't drag it upwards.
It's not a perfect number. It looks backwards, it needs enough copiers to mean anything, and it says nothing about next week. Traders without enough copier history are listed at the bottom rather than guessed at. But it answers the question you actually have when you look at a leaderboard: if I'd copied this person, how would it typically have gone?
And we flag the obvious bad pattern
If we detect a trader selling into their own copiers' buying within the last 30 days, the leaderboard says so. That isn't an accusation, because thin liquidity can create the pattern on its own. It's information, and you should have it before you hand someone a slice of your budget.
What this means for you
- A trader with huge personal profit and a negative median copier P&L is a trader whose followers lost money.
- A modest trader whose copiers are consistently in the green may be the better follow.
- Whatever the number says, copy with limits. A per-trade cap and a daily budget are not optional extras.
