Why OpenTraderWorld?

• 🆓 Free. No subscription, no paywall, no "pro tier". Free for everyone, whether you
  trade for a living or on the side. The idea behind it: get profitable before spending a dime.
• 🔒 Private and self-hosted. It runs on your computer or your server with Docker. No
  account, no cloud, no telemetry. Right after install it only answers on localhost, until
  you decide otherwise.
• 🧩 Modular. 25+ modules. Install what you use, detach the rest.
• 🔁 Updated constantly. New modules and improvements land regularly. The app tells you
  when a version is out, updating is a couple of commands it shows you, and your data always
  survives the upgrade.
• 🗳️ Built with its users. Feature ideas come from the people using it. Suggest yours,
  vote on other people's, watch the roadmap move. See Contributing ideas.
• 🌍 7 languages. English, French, German, Spanish, Italian, Portuguese, Chinese.
• 🤖 AI built in, on your terms. There is a built-in
  assistant that chats with your own
  data. You bring the provider (Anthropic, or any OpenAI-compatible endpoint), and it gets
  memory, skills and tool access scoped by token. There is also a built-in
  MCP server, so external agents
  can read or update your modules through that same token-scoped gateway. Both are off until
  you turn them on. Your keys are encrypted at rest and never reach the browser.
• ⚙️ Automate as much or as little as you like. The
  automator turns your routines
  into scheduled workflows: imports, reports, market scans, alerts, daily reviews. Any of them
  can hand a step to your own AI model, or be driven by it from end to end. You stay in charge
  the whole way: nothing runs, sends or writes anything you did not switch on yourself.
• 🔑 Secrets stay sealed. An encrypted Vault
  holds the credentials the app needs on your behalf. Encrypted at rest, write-only once saved,
  and plugged into any module by reference so you never paste them twice.

Quick start

You need Docker (macOS, Linux or Windows).

curl -fsSL https://raw.githubusercontent.com/G-OTW/OpenTraderWorld/master/install.sh | bash

The installer asks a few questions, generates strong secrets, pulls the prebuilt images and
starts the stack, creates your admin account and prints its password once. Then open
http://localhost:5454 and sign in. If you want the long version (manual setup, headless
servers, LAN/HTTPS/public exposure, backups), it is all in
the documentation.

If the page won't load over plain HTTP. Browsers with HTTPS-only mode (Chrome/Edge
HTTPS-First, Firefox HTTPS-Only, Safari) rewrite http:// into https:// and then cache
that redirect, so a LAN install answers nothing at all. Open the address in a private
window to confirm that is what is happening, then allow HTTP for that host. Or switch to
the LAN + HTTPS mode in Settings → Network and get a real certificate.

Try it without installing

There is a public sandbox at demo.opentraderworld.com,
also linked from the website. No account, no install, and it
comes seeded with realistic data so you land in an instance that looks used rather than empty.

One thing to keep in mind: it is shared. Everything you type is visible to other visitors,
the whole database is wiped and re-seeded every 15 minutes, and settings, connectors and
secrets are read-only. It runs on a small free-tier server with free AI models, so it is
slower than a local install. For anything real, install it. Two minutes.

What's inside

Every module ships with the app. Install what you use, detach the rest.

Backtesting: signals, grid, DCA

One engine, three ways to describe a strategy. No code.

• Signals. Entry and
  exit rules from indicators, price and values, long or short, with stops, pyramiding, and
  sizing by percent of equity, risk per trade, Kelly or equity tiers. Build your own indicators,
  and the chart draws the same ones.
• Grid. A ladder
  of levels between two bounds, long, short or neutral. Each cell buys low and sells one level up.
• DCA. A
  weighted basket bought over time, never rebalanced: recurring contributions, buy tranches on a
  dip, sell rules on a gain objective. Measured like a savings plan, with IRR and a
  deposit-adjusted drawdown.

Run any of them on one instrument or a whole portfolio, with exposure limits and a per-asset
breakdown.

Optimizer

Take a run and vary its parameters: indicator lengths, thresholds, stops, sizing, costs,
portfolio limits, grid settings, DCA amounts, excluded weekdays. Each gets a from / to / step.

• It prices the job first, from what past runs measured on your own machine. Stop at any
  point and keep what is computed.
• Rank on Sharpe, Sortino, return, profit factor, win rate, expectancy, drawdown, trades or
  out-of-sample return. Any column re-sorts after.
• The spread matters more than the winner: worst, average, best, and how many variants came
  out positive. One good number surrounded by terrible neighbours is noise.
• A multiple-testing haircut puts the best Sharpe against the bar the best of N worthless
  strategies would clear anyway. Below it, the winner is explained by the number of tries.
• Click any variant to read its full backtest. Nothing is stored until you keep it.

Add an in-sample / out-of-sample split and the two stat blocks sit side by side. A wide gap
between them is overfitting.

Paper trading: the backtest, left running forward

Press one button on a run you like and it keeps going on new candles. There is no second
engine and no serialized simulator to drift: each tick reloads the window, runs the ordinary
backtest, and diffs the trades against what is already stored. A session opened from a result
reproduces that result exactly.

• Its own schedule: every N minutes, daily, weekly, monthly or once, in your timezone.
• Live alerts on entries and exits, or a period summary instead. Alert on every tick,
  only when something changed, or never.
• Digest it: hourly, daily or weekly, so a two-minute rule does not mean a two-minute ping.
• Your wording, not ours. Entry, exit and summary messages are templates you write, with a
  preview against a sample trade before you save.
• Anything the app could not deliver waits in the session inbox. You read it at the next login.

Filter alerts down to the tickers you care about, and pick which channels a session pushes to.

Data connectors

One connector list for the whole app. A connector is a provider account, its credentials
(typed in or plugged from the encrypted Vault, write-only once saved), an optional request
limit, and the modules allowed to use it. Modules have no provider settings of their own.

Every provider connects directly, with an API key or none at all. Interactive Brokers is the
exception: you run IB Gateway or TWS yourself and the connector stores a host and a port.
Details in the connectors guide.

Live feeds

Missing a provider? Ask for it and it gets
added.

Notifications

These are the notification methods available today. More are planned: if your preferred one is
missing, ask for it.

Secrets are sealed on save and never shown again. What can notify you: paper trading sessions,
watchlist alerts, reminders, finished or parked data downloads, new mail, journal jobs,
inbound webhooks, and any automator workflow. Everything is off until you switch it on, and
in-app notifications work without configuring a single channel.

⭐ Enjoying it? Help it grow

OpenTraderWorld is free and built in the open. If it is useful to you, the easiest way to give
back costs nothing:

• Star the repo. It is a quick signal, and it helps other people find the project.
• Share it. A word to a fellow trader, a link in your community, a mention anywhere. It
  helps more than you would think.

No pressure. Even just trying it out and telling a friend means a lot. 🙏
