In backtest, only 27% of 0xff1e…5e2d's buys could be fully copied at a 5-minute delay

Politics 0xff1e352d5310eab17d1e9fd7e00ec33f16c05e2d Profile on Polymarket

Only 27% of this trader's buys could be fully copied at a 5-minute delay, and another 9% only partly; the +$1,849 comes from the part you could copy. A copier who mirrored 0xff1e…5e2d's 1,013 buys across 247 markets with a 5-minute delay and $100 per trade would have made +$1,849 — more than the leader's +$1,413 at the same size, so the copier kept all of the leader's returns and more (130.9%). That happens when prices keep moving the leader's way after they buy and a later entry ends up cheaper: the delay helped by +$699.71, slippage $24.37 and fees $238.84. A small sample can flip this, so compare the other delays and the trades below. In the backtest, this simulated copy would have tied up to $18,012 at once across 370 positions.

Copy delay

Each time the trader buys, the simulation copies this much. Not a total budget.

The headline numbers only count what real trades in the 10 minutes after the delay prove. “Including estimates” also counts the unproven part of a buy when order-book or trading-volume evidence says it was fillable, at an estimated price. Treat it as an upper view, not a promise. 654 estimated: 127 high · 428 medium · 99 low · 83 thin How we estimate

Leader PnL is scaled to your per-trade size. Delay cost is the price move between the leader's fill and yours; slippage is walking the book to fill your size; fees use the 2026 fee schedule. Methodology.

Trades

Each leader buy and the copy we simulated at the selected delay. Open “Details” to see the market fills behind the copy price.

How fills are simulated: a copy can only fill against real taker buys of the same outcome within 10 minutes after the delay, so the headline numbers are conservative. Fill basis adds a second opinion: where no trade proved a fill, order-book or volume evidence may say the size was still fillable (an estimate, never in the headline). Methodology.
