The honest backtest

Headline returns assume zero slippage.
Real copying doesn't.

The Copy Simulator replays a wallet's real fills against any wallet. You set starting capital, time window, copy-bot latency, fees, and slippage — it gives back an equity curve, the final return, the worst drawdown, and an itemised takeaway showing exactly how much return you lose to latency, fees, and slippage.

Why headline returns overstate what you'd make →

The gap nobody else shows

Four reasons the number you see is not the number you get.

Every other tool optimises for a bigger headline. The simulator optimises for the number you'll actually realise.

Leaderboards quote gross, not net

The number on a copy-bot dashboard is the leader's gross PnL. You will never see that as a copier. The simulator replays the wallet's real fills and takes the costs out first.

The latency tax

Your copy fills a beat after the leader's, at a worse price. The replay models that delay on every mirrored fill — the faster your bot, the smaller the bite.

Fee drag is per-fill

Every mirrored fill pays the fee, on both the entry and the exit. High-frequency wallets that look great on a leaderboard are exactly the ones fees eat the hardest.

Slippage on every fill

The leader's printed price isn't the price you'd actually get. The replay discounts the gap on each fill — the missing cost every other tool ignores.

Honest takeaway

The leaderboard says +41.2%. The simulator says +18.7%. Of the 22.5-point gap, 14.8 is lost to latency and 7.7 to fees — before you ever place a trade.

Why we built this

A flat-fee subscription means we'd rather show you a lower number than oversell a wallet.

Every other tool in this category is paid in basis points of the trades it routes — so every other tool has a quiet reason to make wallets look more copyable than they are. We charge a flat subscription. If the honest number is +18.7% instead of +41.2%, that's what we'll show you. The disappointment, on purpose, is the educational payload — it's what you needed to know before you copied.

Numbers are derived, not custodied. CopyGrade never executes a trade and never holds funds — the simulator is analysis only.
