Wallet C, 13 September 2026 (UTC), from the study’s 30-second, base-cost replay. The wallet’s euros are its SOL amounts at that minute’s SOL price. Prices are one-minute candles, so both of your trades use the 17:50 price; the wallet had sold before you bought.

The study: September replays

The study behind the check: we replayed every swap of three busy wallets through September, minute by minute, with a follower reacting late and paying real costs. Change the delay and costs on the report.

The tools changed. The order didn’t: someone trades first, and everyone who copies them pays to be second.
