Social trading shows you someone else's entry and a notification. By the time you tap it, the candle you were copying has already happened. LAG puts a number on the gap — on Robinhood Chain, where most of that copying now happens.
Pick one of the tokens moving on Robinhood Chain right now, set your delay, and we pull real minute candles, find the moves a trader would have posted about, and compare their fill to the one you'd have gotten arriving late.
Freshly deployed pools — where copying actually costs something. Most of these will go to zero; that's the point.
No black box. Four steps, all of it on public candle data you can check yourself.
Minute-by-minute OHLCV from the pool's first hours, not the quiet days afterwards. The claim is about copying during a launch, so that's the window we measure. Public market data, no wallet, nothing stored.
A trader posts when something actually moves. We take minutes that clear this token's own 90th-percentile move, never under 1.5%, and only with a volume spike behind them. On a calm blue-chip pool nothing qualifies — that's the honest answer, not an error.
The leader was already in as the move began, so they fill at the candle's open. You only see the candle once it's printed, so you fill at your delay. Same exit for both — the only variable is time.
Median, not average — one lucky 40× would otherwise make copy trading look brilliant. The gap between the two medians is the lag tax.
The calculator is the wedge. The real product is accountability for the people you copy.
Every leaderboard ranks traders by their own returns. We want to rank them by what the people copying them actually made.
Measure your own fill latency once, then every number on the site is calibrated to you instead of a slider you guessed at.
Before you copy, one line: at your delay, this setup has historically cost followers more than it made them.
