🤖 Polymarket copy trading bots — what they do and how to choose one

A Polymarket copy trading bot watches wallets you choose and mirrors their trades from your balance, at a size you set. Several such tools exist — many, like Polyfox, run as Telegram bots — and they differ less in the core idea than in fees, controls and how much they let you verify. This page explains what these bots actually automate, then gives you a checklist you can apply to any of them, including ours.

What a copy trading bot automates

Copy trading is a simple loop, and a bot automates each step:

1. Watching. The bot monitors the on-chain activity of wallets you selected. On Polymarket this is possible because trades settle publicly on Polygon — no scraped screenshots, just chain data.
2. Sizing. When a watched wallet trades, the bot computes your mirrored size from your rules — typically a percentage of the target's trade or a fixed dollar amount — and checks it against your limits.
3. Placing. If the sized order passes your filters, the bot places it from your balance; if not, it skips. Selling works the same way in reverse when the target exits.

That is the whole product. Everything that separates one bot from another lives in the details: what it charges, what controls it gives you, and what it lets you verify.

The checklist — apply it to any bot

Before connecting money to any copy trading tool, get clear answers to these questions:

• Fee transparency. What exactly is charged, per what, and where is it written down? Is there a subscription, a deposit cut, a withdrawal fee, a spread markup? A fee you cannot state in one sentence is a warning sign.
• Sizing controls. Can you set a per-trade minimum and maximum? Percentage and fixed sizing? What happens to trades your rules would shrink below the minimum — skipped, or bumped up without asking?
• Risk controls. Price bands (don't copy buys above X¢), take-profit and stop-loss, slippage limits — and above all a working off switch: can you pause or delete a copy instantly, at any time?
• Key export — are you locked in? If your funds sit in a wallet the bot created, can you export the private key and leave whenever you want? A tool that cannot answer this plainly is asking for trust it hasn't earned.
• Verifiable track records. Are the "top traders" it advertises real wallets whose history you can check yourself on-chain, or unverifiable claims? On Polymarket, reading a trader's record is always possible — a bot that doesn't link primary sources is choosing not to.
• Notifications. Does it tell you about every action — each executed copy, each skipped one, each sell? Silence about skips hides how faithfully you are actually copying.
• Remainders and edge cases. What happens on partial fills, dust positions, or when the target splits an exit across many small sells? Bots differ most where trades get small.

None of these questions is about performance. A bot cannot make a copied wallet profitable — the only things it controls are cost, faithfulness and your ability to leave, so those are the things to evaluate.

What no bot can promise

A copy trading bot automates entering risk at your chosen size — it does not reduce risk, and it cannot turn a wallet's past into its future. Any track record, however verifiable, is historical data, not a forecast; copied positions can lose all of their value, and the catalogue of what can go wrong is in Copy trading risks. Whichever tool you choose, choose it on the checklist above — not on anyone's implied returns. This page is informational only and is not investment advice — see Legal notes.
