AmiBroker alternative that backtests in plain English, no AFL code
AmiBroker is a fast, powerful backtester, but it runs on AFL code, installs on Windows, and needs a separate data feed. Agenttrading tests the same idea from one plain-English sentence, with 20+ years of adjusted data already included.

Credit where due - what AmiBroker does well
- ✓ Very fast 64-bit engine that can optimize thousands of parameter combinations
- ✓ Powerful AFL scripting for fully custom strategies, portfolio backtests, and Monte Carlo
- ✓ One-time license with no monthly subscription, data feed billed separately
The honest comparison
AmiBroker has earned its reputation among systematic traders. The 64-bit engine is fast, it handles portfolio-level backtests, walk-forward optimization, and Monte Carlo simulation, and a single-user license is a one-time purchase rather than a subscription (Standard is around $299, Professional around $379, with 24 months of upgrades). If you are a programmer, that is a lot of capability for the money. The friction is everywhere except the price. Strategies are written in AFL, AmiBroker Formula Language, so every idea becomes code first. The software installs on Windows only. And AmiBroker does not ship market data, so you also subscribe to a separate data feed and wire it in before you can test anything. For a full-time quant that setup is worth it; for someone who just wants to know whether an idea held up, it is a project. Agenttrading is the opposite trade-off. It runs in the browser with nothing to install, 20+ years of split- and dividend-adjusted daily data is already loaded, and there is no language to learn: you type the thesis in plain English, it restates the rule, backtests it with a 0.1% cost per trade assumed by default, explains the risks in words, and stamps an honest verdict, HELD UP, MIXED, or UNDERPERFORMED, even when the idea loses to buy-and-hold. Neither tool executes trades. AmiBroker gives a coder maximum control; Agenttrading gives anyone a fast, honest answer. Plans start at $19 per month, it is educational analysis only, never advice, and the decision stays yours.

On the same bench
The plain-sentence workflow is laid out on backtesting software, and multi-holding tests live on portfolio backtesting, the job AmiBroker is best known for. If you are choosing between a coded engine and a code-free one, how to backtest a trading strategy covers the method and common backtesting mistakes covers the traps that catch both. Plans start at $19 per month.
QUESTIONS - ASKED AND ANSWERED
AmiBroker alternatives: the common questions
What is a good AmiBroker alternative?
It depends on whether you want to code. AmiBroker gives a programmer a fast, deep engine, so a like-for-like alternative would be another scripting platform such as TradeStation or a Python library. If you want the same historical answer without writing AFL, a no-code bench like Agenttrading tests an idea stated in plain English on 20+ years of adjusted data, with the data already included.
Do you need to know how to code to use AmiBroker?
For real work, yes. AmiBroker strategies are written in AFL, AmiBroker Formula Language, so every rule becomes a script. There are prebuilt formulas to start from, but testing your own idea means editing or writing AFL. That is the main reason people look for an alternative: they have the idea in words, not in code.
Is AmiBroker free?
No. AmiBroker is a one-time paid license, around $299 for the Standard edition and $379 for Professional, with 24 months of free upgrades. Note that the license does not include market data, so you also pay for a separate data feed. Agenttrading is $19 per month with 20+ years of adjusted data already included, so there is no separate data bill.
AmiBroker vs Agenttrading: which should I use?
Use AmiBroker if you code, want portfolio-level optimization, and will maintain a data feed. Use Agenttrading if you want a fast, honest answer from a plain-English sentence with nothing to install and data included. AmiBroker maximizes control for a programmer; Agenttrading maximizes speed and clarity for anyone, and stamps an honest verdict including UNDERPERFORMED. Neither one places trades.
Can AmiBroker run on a Mac?
Not natively. AmiBroker is Windows software, so Mac users run it through a virtual machine or a compatibility layer, which adds setup and its own quirks. Agenttrading runs in any browser, so the operating system does not matter, which is one practical reason Mac-based traders look for an alternative.
