Who it is for

Mariam Haddad, a dental hygienist in Amman, copied a Hyperliquid leaderboard trader last spring and lost 38 percent in one weekend when he jumped to 20x. Shadow Caps lets her follow two traders again, but her caps rule: no copy above $150 margin or 5x, a $200 stop line for the whole account, and an automatic unfollow the moment a leader falls 20 percent from his peak. Before she follows anyone, it shows her what she would have copied over the last 30 days.

Why it is new

What exists today, and what this does differently

What is new

Copy bots with leverage caps and a stop loss line already exist on Hyperliquid. What we did not find is the follower's own drawdown line on the leader (an automatic unfollow when the leader falls past it, closing the mirrored positions reduce only) together with a replay of what the follower's caps would have copied before they follow anyone.

Closest things out there

HyperX copy trading (position ratio and leverage caps per leader), the open hl-copy-trader agent skill (mirrors a Hyperliquid wallet with a stop loss line and leverage cap), BitMEX copy trading of Hyperliquid traders, and wallet indexes that show each trader's drawdown as a screening metric.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

What it unlocks

The human in it

Lets people learn from traders they admire without handing those traders the keys to their downside.

What you own

The whole app, not a starter kit.

A copy trading app you own where the follower's caps rule: users replay a leader through their own limits before following, copy inside those limits, and get unfollowed automatically when a leader breaks their line. You earn from your own paywall; your console runs pricing, leader rules, growth and the copy agent.

The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.

The need

People copy traders they admire and inherit the trader's worst day along with the good ones. When a leader jumps to 20x or starts revenge trading, followers find out from a liquidation, because most copy tools follow the leader's sizing rules, not the follower's.

What exists and what is new

Copy trading on Hyperliquid exists in several forms: HyperX scales a leader's entries with position ratio and leverage caps, an open hl-copy-trader skill mirrors a wallet with a stop loss line, and BitMEX lets users copy Hyperliquid traders. Wallet indexes already show each trader's drawdown, but only as a screening number. What Shadow Caps adds: the follower's drawdown line on the leader triggers an automatic unfollow that closes the mirrored positions reduce only, every copy is clipped by the follower's own size, leverage and loss caps, and a replay shows what those caps would have copied before anything is followed. Research verdict: partly exists, medium novelty.

The data it runs on

1.The mission

Let anyone learn from a trader they admire while keeping their own rules in charge of their own downside.

2.Why people can't resist it

What you would have copied Before you follow anyone, a replay of their last 30 days through your caps: which trades you would have taken, which your caps clipped or skipped, and where your account would be.

The unfollow line Draw a line on the leader, like 20 percent below their peak. Cross it and Shadow Caps unfollows for you and closes your mirrored positions, even at 3 AM.

Caps card A shareable card that shows how far the leader fell and how far you fell. The gap is the product.

8.Where this is going

Now
One person follows a trader they admire with caps that keep their worst day small.
Next
Base and more perp venues on the same cap card, and clubs that share one stop line across their leaders.
Later
Leaders compete on how their followers fared after caps, not on raw returns, so steady traders get followed.
The world it builds
Copying a trader becomes like learning from a teacher: you keep your own limits, and nobody can lose you more than you agreed to.

Why own Shadow Caps

Copy trading is popular and painful: followers inherit a leader's worst weekend. Owning Shadow Caps means you run the copy app where the follower's caps rule, where every leader is replayed through those caps before anyone follows, and where a leader who breaks a follower's line gets unfollowed automatically. Trading communities already argue about who to copy. You give them a safer way to do it, and you earn from the plans.

What’s stopping you?

“I am not a trader. Can I run a copy trading app?”

You do not pick trades or leaders. Users choose who to follow and set their own caps. Your job is running the app, the listing rules for leaders and support. The cap engine is plain code you can read.

“What if a user loses money and blames me?”

They can. Caps limit how much, not whether, and the app says so on every screen that copies a trade. Users trade from their own account through a permission that cannot withdraw, so you never hold their funds. Keep your terms clear and never market leader returns.

“Is copy trading legal where I live?”

Rules differ by country and some treat copy services as investment advice. Many owners run it as software that executes the user's own rules, with no leader recommendations and no performance promises, and take local advice before charging users. Check before you launch.

“What if Hyperliquid changes its API?”

The app depends on public info endpoints and API wallets, which are core Hyperliquid features. Delivery includes a guide to the endpoints used, and the reconciler fails safe: if it cannot read positions, it stops copying instead of guessing.
