An AI trading agent for Hyperliquid that tests first

Key points

• Nox scores any Hyperliquid wallet out of 100 on six things and prices its costliest habit in dollars, by replaying a simple rule over the real trades, counting the trades it would have hurt too.
• It checks every open position for a stop, adds or moves stops on positions you already hold, and can keep a stop that only moves your way, resting on the exchange.
• Your limits (a daily loss, a drawdown halt, trades a day, a pause after a losing streak, leverage and size caps) are checked before anything opens. Closing is never blocked.
• Strategies are built from fixed building blocks, never code. Each is tested on up to 180 days of past prices before you decide, then runs live on Hyperliquid or in practice with pretend money.
• Every position a strategy or a copy opens gets its own stop on the exchange. Nox's trading key can place and cancel orders, but it can't withdraw or send money.

Most traders don't lose on their picks. They lose on habits: no stop on a position, a winner given back, fees paid on every fill. Nox, the AI agent on nox.cool, now works as a trading desk for Hyperliquid. It finds those habits in your real trades and prices them in dollars, protects what you already hold, keeps to limits you set, and runs strategies around the clock, but only after testing them on past prices first, and in practice with pretend money if you like.

#The problem: trading tools talk, or they trade blind

Leveraged trading is hard on people. When Europe's markets regulator restricted leveraged CFDs in 2018, it found that 74–89% of retail accounts typically lose money. The reasons are rarely mysterious. Positions go on without a stop. A trade that was up 8% closes at a loss. Market orders pay the higher fee every time.

The tools on offer mostly sit at two ends. Chatbots will talk about markets all day but can't see your trades. Trading bots will place orders but rarely tell you, in plain words, what a rule would have done before you hand it money. We wanted Nox in the middle: an agent that looks at your own record first, shows its working, and asks before anything new opens.

#Score your trading

Ask Nox "score my trading" for your connected account, or "score this wallet: 0x…" for anyone's, since Hyperliquid's trades are public. Nox reads up to 180 days of fills and funding (90 by default) and returns one card.

The card has four parts:

• A score out of 100 on six things: risk management, consistency, timing, costs, market fit and sizing, with a one-line verdict ("profitable over the window; weakest on risk management").
• Where the money went: trading profit, fees and funding, each on its own line, so you can see what costs really took.
• The biggest leak, in dollars. Nox replays one simple rule over your real trades: a stop at a set loss, a stop that follows the price once a trade is in profit, a time limit, a size cap, a cap on funding, or not chasing a move. It counts what the rule would have saved and what it would have cost on the trades it cut short. Leaks overlap, so they're never added together. A leak that comes from a single trade isn't called a habit.
• What's open now, with how each position is protected and how far its liquidation price is.

A rule that would have saved $2,640 on some trades and lost $512 on others is worth $2,128. Nox shows both numbers.

The same report is free for anyone at nox.cool's trading score page, with no sign-in, and each result has its own link to share. There's also a "Trading coach" agent in the gallery that runs the review every Monday and tells you whether the habit is improving.

#Are my positions protected?

This is the question Nox answers fastest. Ask it, and Nox checks every open position for a stop resting on the exchange, works out how far liquidation is, and suggests a stop outside the market's normal daily swing (one and a half times the average day's range).

Say yes and Nox places them. It can now add or move a stop or a take-profit on positions you already hold on Hyperliquid, Aster and Binance. On Hyperliquid it can also place orders that rest on the book first for the lower fee, sending what's left at market after 30 seconds.

#A stop that only moves your way

A fixed stop protects you from a bad trade. It doesn't protect a good one. A stop that follows the price starts as a normal stop, then, as the trade gains, locks in a growing share of the best gain so far. nox.cool checks every 10 seconds and raises the stop on the exchange when it's worth moving. It never lowers it.

Ask "trail my ETH long, balanced", or give your own steps. Because the stop itself sits on the exchange, it fires even if nox.cool is offline.

#Limits you set, checked before anything opens

Most of the damage in a bad week happens after the first loss. So Nox keeps limits that you set in plain words: "stop me trading for the day if I lose $100, and never more than 5× leverage". It can also:

• halt at a drawdown from the account's high,
• cap trades a day (with an exception on days you're up, if you want one),
• pause after a run of losing trades,
• keep off a coin for a while after closing it,
• cap any one position as a share of the account.

Every new position is checked against them first, whether you asked for it, a strategy found it, or a copy is following someone. If the account's numbers can't be read, nothing opens. Closing is never blocked, so you can always get out. Every change to your limits asks you on a card first.

#What's moving, and who's worth watching

Nox reads every Hyperliquid market every 5 minutes, and every 10 minutes it reads the open positions of three groups: the proven traders (at least $1M of all-time profit and a $50,000 account, market makers left out, the top 150), this month's 60 hottest, and a spread of 260 ordinary accounts.

From that come four things you can ask for:

• The market's day: crypto, stocks, commodities and currencies, risk-on or risk-off, and the biggest movers.
• Where the big money leans, coin by coin, and where the proven traders disagree with the crowd.
• Unusual moves: open interest surging, a sharp move on heavy volume, a proven trader opening a $1M+ position.
• Top traders, ranked by how steady and copyable they are rather than by raw returns, with honest flags such as "20×+ leverage open" or "splits orders into many small fills".

Any of them can become an alert: "tell me when the proven traders flip on BTC", or "tell me when 0x… opens a position".

#Strategies that run around the clock

A strategy on nox.cool is a set of rules made from fixed building blocks: breakouts, trends, pullbacks, the edges of a range, RSI, volume spikes, tight ranges about to break, funding, open interest, where the proven traders lean, signals from the feed, and the hours of the trading day. Each has its exits (a fixed stop, a stop that follows the price, a take-profit, a time limit) and its own safety rails. No code from anyone runs on our servers: a strategy is data that Nox checks, never a program.

There are 25 ready-made strategies to start from, such as Trend Rider, Pullback Buyer, Range Trader, Funding Fade, Whale Tail, Gold Trend, Oil Breakout and AI Chips Momentum. Or describe your own: "go long ETH when it breaks the week's high on twice the usual volume, with a 3% stop".

#Tested on past prices first

Before you decide, Nox tests the rules on past candles: 10 days for a strategy that looks every 5 minutes, up to 180 days for one that looks every 4 hours. The test is deliberately cautious:

• a trade enters at the next bar, not at the price that triggered it;
• when one bar touches both the stop and the take-profit, the stop wins;
• rules that only exist live (funding, open interest, the big traders' positions, feed signals) are named and left out, and if nothing testable is left, Nox says so instead of showing a number that means nothing.

Some ready-made strategies lose money on past prices. Nox shows those results too.

#Then live, or in practice

Approve the card and the strategy runs on your Hyperliquid account, or in practice with pretend money at live prices, with the same rules and stops. It looks at the market on its own clock and tells you each time it opens or closes something. Every position it opens gets a stop resting on the exchange, and if a stop can't be placed, the position is closed again straight away.

Library › Trading lists every strategy, the stops that are following your positions, and your limits in one place.

#Copy a trader, with your own stop

"Copy 0x… in practice with $200, only their new trades." A copy follows what another trader opens, at your size: their position scaled by your budget over their account, at most a set share of your budget per position. When they close, the copy closes. It skips a copy when the price has already moved 2% past their entry, or when it would fall under Hyperliquid's $10 minimum. And each copy gets its own stop that follows the price, because their risk isn't yours.

#Stocks, gold and oil on the same account

Hyperliquid also lists markets for stocks such as NVDA and AMZN, gold and silver, crude and Brent oil, indices and currencies, built on its builder-deployed perpetuals. Nox trades, protects and reads them like crypto: say "gold" or "oil" and it finds the right market, with each market's own margin rules.

#A real example: a gold strategy, tested and practised

In one of our tests we asked: "I want a strategy that trades gold. Find one, test it on past prices, and if it looks sensible start it in practice with $500 of pretend money."

Nox looked through the ready-made strategies, picked Gold Trend (long when a 4-hour close breaks the last nine days' high with gold above its 50-day average, short on the mirror image), and tested it on 180 days of prices. The test made only six trades, and Nox said so. Then it showed the start card: $200 of margin at 3× per position, one at a time, a stop 2% below the entry that would cost about $12 if hit, and a stop that moves up as the trade gains. We approved it.

An hour later we asked "is everything running?". Nox answered that Gold Trend was running and hadn't traded yet, and why: the trend rule was true, but gold hadn't broken out. That's the point of a slow strategy, and it's the kind of answer you want before you trust one with real money.

#What keeps you in charge

• Every start asks. A live strategy, a copy, a trade and every change to your limits wait for your OK on a card that says exactly what will happen, including what one stop-out costs.
• The trading key can't withdraw. Your wallet approves a key that can place and cancel orders on your Hyperliquid account for 179 days. It can't withdraw, send or move money out, and nox.cool never holds your money or your wallet's keys.
• Stops live on the exchange, so they fire even if nox.cool doesn't.
• Limits fail closed. If they can't be checked, nothing opens.
• Facts, never tips. Nox tells you what happened and what your rules would do. It never tells you what to buy. A test on past prices is not a promise about the next trade.

#Questions and answers

What is an AI trading agent?

An AI trading agent is software that reads markets and your account, and acts on rules you approve: placing orders, moving stops, or running a strategy while you're away. Nox, the agent on nox.cool, does this for Hyperliquid. It gives facts and runs your rules; it never tells you what to buy.

How does Nox score my trading?

It reads up to 180 days of your Hyperliquid trades (90 by default) and scores six things out of 100: risk management, consistency, timing, costs, market fit and sizing. It shows trading profit, fees and funding separately, and prices the habit that cost the most by replaying one rule over your real trades, net of the trades the rule would have hurt.

Can I test a strategy before risking money?

Yes, twice. Every strategy is first tested on past prices (up to 180 days, depending on how often it looks), with the worst fall shown. Then it can run in practice: pretend money at live prices, with the same rules and stops, for as long as you like.

What happens if nox.cool goes down while I have a position open?

Every stop Nox places rests on the exchange itself, so it fires on Hyperliquid's side even if nox.cool is offline. A stop that follows the price is raised by nox.cool every 10 seconds, and it never moves back.

Can Nox withdraw my money?

No. Your wallet approves a trading key that can place and cancel orders on your Hyperliquid account for 179 days. It can't withdraw, send or move money out. nox.cool never holds your money or your wallet's keys.

Can I trade stocks, gold or oil this way?

Yes, on Hyperliquid's own markets for them: stocks such as NVDA and AMZN, gold, silver, crude and Brent oil, indices and currencies. Nox trades, protects and reads them the same way it does crypto.
