Quantradin is a paper trading sandbox built for AI agents. Most backtests fill you at prices you would never get; Quantradin does not. You get a $100,000 paper desk wired to real quotes: you buy at the ask and sell at the bid, never the middle, because nobody fills you there, and every fill is written down at the price it really paid. A rule running at 10:00 only sees prices up to 10:00: no look-ahead, ever. Your AI gets its own desk. Paste the connect prompt into any assistant (Claude, Gemini, Codex, GPT, terminal or desktop) and it writes the strategy, tests it, and runs the ones you approve. Agents get API keys: a full key that can trade, and a read-only kind that can watch or close positions but never open one. Your bots run the whole session, open to close, without you watching, and a stop rule sells at the bid on the bar where it fired, never on a friendlier bar an hour later. The engine also gives you its honest read on your strategy, tested on years it never saw, printed beside your own choice. It is an opinion, never a gate: you decide what runs. Pricing is founder-friendly right now: everyone is on the paid plan for nothing during the founding era, and joining now keeps a permanent founder's discount. The free plan stays $0 forever (20 stocks per run, 10 backtests a month, 1 paper desk, 1 bot, daily bars, AI agent connection included). When billing starts, the full plan is announced at $12/month or $99/year: 300 symbols, unlimited backtests, 3 paper desks, 10 bots, all 158 indicators and every option structure, intraday clocks from 1 minute to 4 hours. There are no card fields anywhere on the site today. Honest caveats: paper money only. This is simulation and learning, not investment advice. It is a young product in its founding era, so features and limits can move. The free tier runs on daily bars; intraday data needs the paid plan once billing starts.

Install
Copy the install package below, then paste it into MuseCommunity-built. Skill Harbor doesn't audit code — review the source before installing.
Give your AI a trading desk on Quantradin. 1. Create your account at quantradin.com (no card, nothing to cancel). 2. Open "Give your AI a desk" and copy the connect prompt. 3. Paste it into your assistant of choice: Claude, Gemini, Codex or GPT, in the terminal or on desktop. From then on it writes the strategy, tests it against real prices with no look-ahead, and runs the ones you say yes to. 4. For tighter control, generate API keys from your desk: a full key for the trading agent, and a read-only key for watchers (they can watch or close positions, never open one). 5. Read the engine's honest read beside your results: it grades your strategy on history it never saw. You decide what runs. Tip: start with the no-signup bench on the homepage to watch the engine grade a famous strategy in a few seconds.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
