Take-profit strategies for copy trading

Copy trading solves the entry for you. Someone you trust bought "Yes" at $0.62, your bot bought a moment later, done.

The exit is still your problem. The trader you copied has a plan for getting out — maybe. You need your own answer, and it's worth deciding before the position exists, not while it's swinging.

On Polymarket there are exactly three ways out of a winning position: hold to settlement and collect $1 per share, sell when your copied trader sells, or sell at a target you set yourself. Polymarket's help center confirms you can sell any time before resolution. This post is about choosing between the three.

The last cents are the riskiest cents

Here's the thing about a share sitting at $0.93. Holding it to settlement earns you 7 more cents if you're right — and loses 93 if you're wrong. From that price, you're risking thirteen dollars to win one.

That can still be a fine bet. If the true probability really is 95%, holding is correct. But notice what you're doing: you're not "letting a winner run" like in stocks, where a winner can double again. The upside is capped at $1. Every cent the price rises, your remaining upside shrinks and your downside barely moves.

Run the numbers on 100 shares at a $0.90 bid in a crypto market. Sell now as a taker and the fee is 100 × 0.07 × 0.90 × 0.10 = $0.63, so you clear $89.37. Hold, and the position is worth $93 on average if the true probability is 93%. You'd be paying about $3.63 per hundred shares for certainty and instant cash.

Is that worth paying? Honest answer: it depends on something nobody knows — whether the market price is right. If the crowd is overconfident and the real odds are 88%, holding is worth $88 and selling at $89.37 was the better trade. If the market is underpricing a near-lock, selling gives away real money.

A workable rule for copy traders: above $0.90, sell unless you have a specific reason to believe the market is too cheap. You copied the entry because someone else had information. At $0.93 their information is already in the price.

The fee curve is on your side near the top — and limit orders beat it entirely

Polymarket's taker fee follows a curve: shares × rate × p × (1−p). It peaks at 50/50 — $1.75 per 100 shares in crypto markets — and shrinks toward the extremes, down to $0.63 per 100 at $0.90. Sell fees come out of your proceeds the same way. The full fee breakdown is its own post.

But you often don't have to pay it at all. Makers pay nothing. A resting limit order that someone else fills is a maker order — so if your plan is "sell at 0.90," place the limit sell at $0.90 in advance instead of watching the price and market-selling when it gets there. Same exit, zero fee, and no crossing the spread — order-book guides estimate working the spread saves 2–3 cents versus a market order on a typical book.

The catch, straight from the help center: a limit order only fills if a willing buyer shows up at your price. On a liquid market that's routine. On a dead one your target can sit unfilled while the price walks away. That's the trade you're making.

The ladder: how to exit a cheap entry

Everything above assumed you're holding a favorite. Cheap entries deserve a different plan.

Say you copied a wallet into 500 "Yes" shares at $0.18 — $90 in. A ladder sells in slices as the price climbs:

• Sell 150 shares at $0.35 → $52.50 back
• Sell 150 shares at $0.55 → $82.50 back
• Let the last 200 ride to settlement → $200 if it wins

Two rungs in, you've recovered $135 on a $90 position — the rest is a free roll. And if the market reverses after the first rung, you lost $37.50 instead of $90. The ladder converts one all-or-nothing bet into three smaller decisions, each made at a better price than the last.

Set the rungs as limit orders (maker, no fee) and mind the book — on thin markets a large sell can eat through several bid levels, which is its own topic. This is also exactly what btc5min's auto take-profit ladder does per wallet: you define the rungs once and the resting sells go out automatically on every copied entry, so you're not watching a screen waiting for $0.35 to print.

Exit-with-them: sometimes the best target is theirs

The third option is to sell when your copied wallet sells. It's the least satisfying — no clean numbers, no control — and it's often right.

The trader you copied knows why they entered. Their exit is information, the same way their entry was. If a sports wallet dumps a position at $0.55 an hour before game time, that's frequently the only warning you'll get before the price explains itself. Your $0.90 target never gets a vote.

Before you decide, look at how the wallet actually exits. Some traders sell well — they consistently get out near highs. Others hold everything to settlement and eat full round trips. Copy the first kind's exits. For the second kind, your own targets exist precisely to skip the last-cents risk they keep choosing to take.

I've watched a wallet ride a $0.78 position all the way to zero on a resolution surprise, twice in one month, while its copiers with a $0.90 limit sell got out of one of the two. Neither approach saved everyone. The ladder-plus-exit-with-them combination — rungs for profit, their sell as an emergency exit — covered the most cases.

Where common advice gets it wrong

"Always take profits early" is the standard line, and blanket-applied it's wrong here. If you copied a strong trader into a $0.60 entry that's now $0.85, systematically selling early gives back a chunk of the very edge you're paying to copy. The skill you borrowed included knowing when a favorite is still cheap.

The version that survives contact with the math: take profits early on cheap entries (the ladder), respect the trader's exit when they have one, and near the top, remember you're risking thirteen to win one.

One more thing: 5-minute markets don't play this game

Everything here is for event markets that live hours to months. Polymarket's BTC 5-minute markets settle before a take-profit plan means much — by the time your target price exists, the round is nearly resolved, and the spread plus taker fee usually eats whatever a mid-round exit would save. In those markets the entry price is the whole decision.
