Setting up a copy takes four short steps: Size, Limits, What to copy and Review. Only the size is required. The other two steps are optional, and Skip to review jumps straight to the summary.
The Review step lists every setting with an Edit link, so you can confirm exactly what the copy will do before you start. When you edit an existing copy, it opens on this review.
1. Size
Choose how each copy is sized.
Same amount every trade
Every copied buy costs the same, whatever the trader bets.
Example (at $5): trader buys $500 → you buy $5. Trader buys $20 → you buy $5.
Quick presets: $2, $5, $10, $25. If the amount is more than your balance, the app offers the largest amount your balance covers.
Note: Polymarket needs at least $1 per order, and amounts under $0.50 are always skipped. A few markets also require at least 5 shares per order, so below $5 per trade those markets only copy prices under a cutoff the app shows you. $5 or more copies every market.
A share of their trade
Copies a share of each of the trader's buys, so their big bets become your bigger copies.
Example (at 10%): trader buys $300 → you buy $30. Trader buys $20 → you buy $2.
When you switch from a fixed amount, the app suggests the share that matches your amount at their typical buy size.
Big trades mean big copies, so turn on Limit each order to keep every copy between a minimum and a maximum in dollars.
Example (10%, limits $2 to $25):
- Trader buys $30 → 10% = $3 → $3
- Trader buys $2 → 10% = $0.20 → raised to $2
- Trader buys $400 → 10% = $40 → capped at $25
Copy preview
Below the size, the Copy preview replays the trader's latest buys with your settings: their typical buy, your typical copy, how many would be copied and how much it would have used. It also warns you, with a one-tap fix where there is one, when:
- Some copies would come out under $0.50 and be skipped (fix: Keep every copy at $1 or more, or use the suggested share)
- Copying their recent buys would take more than your balance
- The trader often buys both sides of a market: a fixed amount copies their small hedges as big as their main bets (fix: Size by their trade)
If the trader has no recent buys, type an amount they might buy and the preview shows what you would buy.
2. Limits
All optional. Leave a field empty for no limit.
| Setting | What it does |
|---|---|
| Pause if I'm down (stop loss) | Pauses the copy when your P&L with this trader reaches -$X |
| When paused at a loss | Keep positions (default), sell all, or sell only losing positions |
| Max invested at once | Caps your open positions with this trader. When positions close, that room frees up again. |
| Pause at a profit of (take profit) | Pauses the copy once your P&L with this trader reaches +$X |
| Max per order | Caps any single order, whatever the sizing |
| Max per market | Caps your total on one outcome of a market (Yes and No count separately), counting all your copies, however many orders the trader places |
- Both limits count realized P&L only: positions sold or resolved since the copy started or was last resumed. Paper losses on open positions don't count until those positions close.
- Your P&L with the trader resets to $0 when you resume a paused copy. Saving new settings keeps it, so a limit the copy has already passed pauses it right away.
- Both are checked about every 15 seconds and before every copied trade.
- While paused by either one, nothing is copied, the trader's sells included. Open positions stay unless your stop loss is set to sell.
A per-trade amount does not cap how much can stack up: if the trader places 10 orders, you copy 10 orders. Max invested at once and Max per market are what cap the total.
3. What to copy
All optional.
Which trades
| Setting | What it does | Example |
|---|---|---|
| Counter-trade | Unavailable right now: a counter copy places no trades. Shown only on copies that already have it, so you can turn it off | — |
| Skip hedges | Skips the trader's buy of the other side when it comes within 5 minutes of a buy in the same market. The first side is still copied | Avoid copying quick two-sided buys |
| Only odds between | Skips buys priced outside a range, and never pays above your max. Sells are always copied | 5% to 85% skips long shots and near-certainties |
| Ignore trades under (min trigger) | Skips the trader's buys below this size. Their sells are always mirrored, however small | $2 filters out test buys |
| Markets ending within (max days out) | Skips markets that resolve later than this | 30 days |
| Min market liquidity | Skips thin order books, which fill at worse prices | $10,000 |
| Min market volume | Skips inactive or brand-new markets | $50,000 |
Selling
| Option | What happens when the trader sells |
|---|---|
| Mirror them (default) | You sell the same share of your position: they sell 50%, you sell 50% |
| Fixed $ | You sell a set dollar amount, or everything if you hold less |
| Fixed % | You sell a set share of your position, whatever they sold |
Auto-sell at (in cents) sells each new position from this trader when buyers bid your target or more (checked about every 30 seconds). Example: 85¢ on a position bought at 60¢ locks in 25¢ per share. Leave it off to exit when the trader exits or the market resolves. You can also set limit sells on individual positions from your Dashboard.
Orders
| Option | Behavior |
|---|---|
| Market (recommended) | Fills right away at the best available price, closest to the trader's entry |
| Limit | Waits up to 2 minutes at a price 0.5¢ to 10¢ better than the current market price. That can still be above the price the trader got. If it doesn't fill: buy at market, or skip the trade |
Limit orders can miss fast markets like sports or 5-minute crypto. Use them only for slower, longer-dated markets.
Low balance
If your balance can't fund an order, that trade is skipped and you're notified. After 5 skips in a row the copy shows Needs funds: new buys stop, but the trader's exits are still copied, so your open copies follow them out. It resumes on its own when funds arrive, whether from a deposit, a sale or a payout.
Common confusion: per order vs per market
The amount per trade (or Max per order) caps each order. Max per market caps your total on one outcome of a market (Yes and No count separately).
Example: $5 per trade, Max per market $15, and the trader places 5 orders in one market:
| Trader's order | Your copy | Your total in that market |
|---|---|---|
| $200 | $5 | $5 |
| $150 | $5 | $10 |
| $100 | $5 | $15 |
| $80 | Skipped (Max per market) | $15 |
| $50 | Skipped (Max per market) | $15 |
Without Max per market, all 5 would copy and you would hold $25 in that market. That is expected, not a bug.
Recommended for beginners
- Amount per trade: $5, or less than 5% of your balance
- Max invested at once: about half your balance per trader
- Pause if I'm down: an amount you're comfortable losing with this trader
- In Limits: Max per market $25
- In What to copy: Only odds between 5% and 85%. Ignore trades under is optional: it skips only the trader's small buys, and their sells are always mirrored
- Keep selling on Mirror them and orders on Market
Start with 2 or 3 traders and small amounts, then raise them as you get comfortable.
