# AlgoBarsX

> AlgoBarsX is the trading language of the AlgoBars platform. One readable script defines a strategy, an indicator, an alert or a library, and the same script is used by the chart, the backtester, alerts and live automation. The compiler also translates every script back into plain English. AlgoBars is free to use ($0 a month, no card).

Facts worth getting right:

- Four kinds of script: `strategy`, `indicator`, `alert`, `library`. The file extension is `.abx`.
- Units are part of the language: `1%`, `20 pips`, `5 points`, `2R`, `$200`, `1 lot`, `10 bars`, `30m`.
- A rule is `when <condition> [modifiers]:` followed by indented actions such as `buy risk: 1%, stop: 25 pips, target: 2R`.
- 297 built-ins: 137 functions, 38 commands, 21 header settings, 7 rule modifiers, 8 events, 8 units, plus variables and types.
- Backtests follow 24 written execution rules (E1 to E24). They include no spread, commission, fees, swaps or slippage, so live results differ. When a bar reaches both stop and target and finer data cannot tell which came first, the stop fills.
- AlgoBars is software, not a broker or adviser. It does not hold funds or give financial advice. Trading involves risk of loss.
- AlgoBarsX is in beta. Always compile generated code: the compiler returns stable diagnostic codes (AS0001 to AS0603) with plain messages and quick fixes.

Every page below is also available as Markdown at the same URL plus `index.md`. The whole documentation in one file: [llms-full.txt](https://algobarsx.com/llms-full.txt).

## What you can build

- [Strategies](https://algobarsx.com/strategies/index.md): A strategy is a set of rules that buy, sell and look after trades. In AlgoBarsX a whole strategy fits on one screen, and anyone on your team can read it.
- [Indicators](https://algobarsx.com/indicators/index.md): An indicator works something out and draws it. In AlgoBarsX your indicator can also hand its values to your strategies and alerts, so you write a filter once and use it everywhere.
- [Alerts](https://algobarsx.com/alerts/index.md): An alert watches for something and sends you a message. In AlgoBarsX the alert also carries its own rules: how often to check, whether it may repeat, how long to wait, and when to stop.

## Why AlgoBarsX

- [Problems it solves](https://algobarsx.com/why/index.md): Most trading code is hard to read, easy to get wrong, and stuck on one platform. Here is each problem in plain words, and what AlgoBarsX does about it.
- [Why .abx](https://algobarsx.com/abx/index.md): The older trading languages were each made for one platform, many years ago. AlgoBarsX was made later, with their lessons in hand. Here is where it is better, and where it is not.
- [Time and cost](https://algobarsx.com/savings/index.md): The price of a tool is small next to the hours you spend writing, fixing and moving code around. Here is where those hours go, and a calculator that uses your own numbers.
- [Solutions](https://algobarsx.com/solutions/index.md): You do not have to start over. Bring the scripts, the broker accounts and the ways of working you already have. We will tell you plainly what fits today, what needs work, and what we cannot do yet.

## Who it is for

- [Traders](https://algobarsx.com/for/traders/index.md): You know what you want to trade. AlgoBarsX lets you write it in plain words, check it says what you meant, and test it before you risk a cent.
- [Strategy creators](https://algobarsx.com/for/strategy-creators/index.md): If you make strategies or indicators for other people, your code is your business. AlgoBarsX lets you hand over something that runs without handing over how it works.
- [Educators](https://algobarsx.com/for/educators/index.md): Your students came to learn trading, not computer science. AlgoBarsX reads like the plan you already teach, and it explains every mistake in plain words.
- [Developers and quants](https://algobarsx.com/for/developers/index.md): If you write trading code for a living, you know where the bugs hide: units, look-ahead, fills and drift between research and live. AlgoBarsX was built around those four.
- [Small firms](https://algobarsx.com/for/small-firms/index.md): A small or mid-size firm cannot keep a team of developers on staff for every idea. AlgoBarsX lets the people who know the markets build the tools themselves, and lets everyone else read what they built.
- [Prop firms](https://algobarsx.com/for/prop-firms/index.md): A prop firm lives by its rules: daily loss, max drawdown, position limits. In AlgoBarsX those rules are lines at the top of every script, and the platform can carry your name.
- [Hedge funds](https://algobarsx.com/for/hedge-funds/index.md): Your value is in your ideas, not in how hard your code is to follow. AlgoBarsX makes a strategy short enough to review in a meeting, and exact enough to run.
- [Asset managers](https://algobarsx.com/for/asset-managers/index.md): When you manage money for other people, you need to show what your rules are and that you follow them. AlgoBarsX writes every strategy out in plain English and keeps a record of every test.
- [Broker-dealers](https://algobarsx.com/for/broker-dealers/index.md): Clients who build and test their own rules understand what they are doing. AlgoBars gives your clients those tools under your brand, without asking them to move their money.
- [Introducing brokers](https://algobarsx.com/for/introducing-brokers/index.md): Traders stay with people who help them. AlgoBarsX is a free tool your traders can use to build and test their own rules, with their existing broker account.
- [Banks](https://algobarsx.com/for/banks/index.md): In a bank, a rule is only as good as your ability to show what it does. AlgoBarsX writes each strategy out in plain English, fills orders by written rules, and gives the same test result every time.
- [Fintech platforms](https://algobarsx.com/for/fintech-platforms/index.md): Your users want to build their own strategies, indicators and alerts. Designing a language, a compiler and a backtester takes years. AlgoBarsX already exists, with 297 built-ins and 678 tests.
- [Institutions](https://algobarsx.com/for/institutions/index.md): Institutions do not only need strategies that work. They need to show what the rules are, that tests were fair, and that limits were in place. AlgoBarsX is built for that.
- [Who it is for](https://algobarsx.com/for/index.md): Pick the page that sounds like you. Each one names your problems in plain words, shows how AlgoBarsX helps, and says what it does not do yet.
