TL;DR: the trade-copier category runs on claims — "lightning-fast", "rock-solid", "set and forget". The complaints that fill trader Discords are the same three stories: it disconnected silently, it slipped and nobody could say by how much, and "did it even copy?" A receipt is the opposite of a claim: a number or an event you can check yourself. This page is the five-question audit we think every copier should pass — with our answers, verifiable live.
Read any copier's reviews (including ours) and the unhappy ones cluster into three shapes: the copier died quietly while the trader thought five accounts were mirroring; a fill slipped and there was no per-order number to say whether the copier or the broker ate the time; and an order just didn't copy, discovered at the end of the day. Surveys of funded traders consistently find a majority reporting technical issues during evals. The product category's real job isn't copying — it's being trustworthy about copying.
| The claim | The receipt |
|---|---|
| "Lightning-fast copies" | Latency measured on every mirror and printed in your Copy Log next to the fill — engine time and broker-wire time split out, so a slow broker can't hide inside our number. Platform-wide median and p95 from real production orders published at /latency. |
| "Always connected" | A staleness bar the moment your data feed goes quiet; a notification on desktop and your phone when a broker login signs out; and a Start button that refuses loudly — naming the dead login — instead of pretending to start against it. |
| "It copied your trade" | A Copy Log row for every copy decision — including rejections and skips, with the reason. We never trim the log to look good; an aggregated failure row beats fifty missing ones. |
| "Reliable infrastructure" | Health-gated deploys that auto-roll back if a build doesn't come up healthy, rolling restarts so an update drops no requests, and a public /healthz anyone can read — including the exact commit running. |
| "Protects your eval" | Risk guardians that act — flattening a cushion above the firm's drawdown or daily-loss line — plus a live Eval HQ board showing every account's distance to its rules in real time, not in tomorrow's journal import. |
Because the category earned the skepticism. Copiers sell trust to people who've been burned, so the honest move is to make every claim checkable: per-order latency in the log, share cards that carry a public verify page (which states plainly what we recorded and what we didn't), and a status page that tells you what's actually deployed. If we have a bad hour, it shows. That's the point.
Fairness cuts both ways. Replikanto's NinjaTrader integration runs deeper than anything browser-based; TradeCopia covers desktop platforms (Quantower, ATAS, Sierra Chart) we don't; TradeSyncer helped define the cloud category. If those fit your stack, they're good tools — our argument isn't that they fail, it's that every copier should show its receipts, and you should ask for them.
Ask these of any copier — including us — before you trust a funded account to it:
Demand per-event visibility: a log row for every copy decision including rejections, per-order latency next to each fill, and an alert the moment a broker login disconnects. Trading Floor shows all three; whatever copier you use, ask where its equivalents are.
Sub-100ms leader-fill-to-follower-order keeps mirrors inside a tick or two on liquid contracts in normal conditions. The number that matters is measured per-order on your own fills — Trading Floor's median is ~42ms, published live from production orders at tradingfloor.me/latency.
Most copiers surface disconnects only in a status widget you have to go look at. Broker sessions (especially OAuth logins) expire, and a copier that stays quiet about it leaves you flat while you think you're trading. Trading Floor pushes a notification to desktop and phone, and refuses to start against a dead login — naming which one.
Yes — every copy decision writes a Copy Log row, including rejections and skips with the reason. Shared cards carry a public verify page that states exactly what was recorded and how.
