Build Alpha

What it is

Build Alpha is a Windows desktop application that searches for trading strategies instead of asking you to write one. You set the constraints — symbols, timeframe, date range, entries, exits, risk management, fitness function — and a genetic algorithm works through combinations drawn from a library the vendor now puts at more than 7,000 signals, covering price action, indicators, seasonality, breadth, yields, economic releases, COT data, news and option flow. What comes out is a ranked list of rule sets you page through, and then code you paste into a trading platform.

The second half of the product exists to attack the first: robustness tests applied to whatever the search returns. A vs-random comparison against strategies built from random signals, a noise test that rebuilds the price series a thousand times with altered volatility and re-trades on each, Monte Carlo drawdown analysis, randomised out-of-sample, across-markets testing, delayed entries and exits, and E-ratio decay curves. Filters can be automated so only candidates that survive a named set of tests reach the screen.

It is written and sold by one person, David Bergstrom, a former market maker and HFT quant, and has been shipping since 2016.

Pricing

The licensing page lists one plan: a Lifetime License at $1,497 one-time, shown against a struck-through $2,497 that has stood unchanged since at least February 2026, including upgrades, portfolio mode and a Fast-Start package of onboarding videos and ten importable starter strategies. Institutional and multi-seat pricing is quoted by enquiry. Payment is by PayPal unless you arrange otherwise.

Subscriptions exist but are not advertised there. The licensing FAQ mentions converting one to Lifetime within 30 days for a $197 fee, and unlinked store pages still carry a Starter at $597 up front plus $59/month, a Pro at $997 up front renewing at $197/year, and annual and quarterly licences at $997/year and $447 per quarter. Treat those as unverified: the shop index they would sit in is a test catalogue of $1.00 placeholder products whose own lifetime listing disagrees with the licensing page by three dollars. If you want a subscription, ask.

There is no trial and no demo build, stated plainly in two places.

Data & coverage

Historical data is included back to 2006 and updated regularly — daily bars as far back as a contract has existed, and intraday from 1 to 240 minutes, with custom bar types supported. You can connect a broker or data provider instead, or import your own files in any format.

Coverage is futures-first: index futures including DAX and Nikkei, Treasury notes and bonds, grains, softs, metals and energy, plus around 30 major forex pairs, stocks and ETFs, and crypto through Binance, Kraken, KuCoin and Massive. Slippage and commission are entered per strategy rather than assumed.

Integrations

Code generation is the point of contact with the rest of your stack: TradeStation EasyLanguage, MultiCharts PowerLanguage, NinjaTrader 8 C#, Python for Interactive Brokers, MetaTrader 4 and 5, TradingView Pine Script and ProRealTime. Execution happens there, not here — the vendor's own wording is that you copy and paste the generated code to trade a simulated or real account.

It connects to brokers and data providers, TradeStation and Interactive Brokers among them, to monitor live positions, open P&L and alerts on saved strategies, and a Daily Position Report lists what to enter, what to exit, exposure and funds available for people not ready to automate.

Version 3.1, announced 1 September 2026, added an LLM orchestrator: supply your own key for any OpenAI-compatible model and it adjusts search hyperparameters between rounds, logging its reasoning. It is optional and can be switched off. Custom signals can be written in Python or the built-in signal editor. There is no public API and no documented MCP server — a lesson in the vendor's members-only Accelerator curriculum describes connecting Claude Desktop over MCP, but nothing public documents it.

Limitations

• This is data mining, and overfitting is intrinsic to it, not an edge case. The vendor's own FAQ does the arithmetic on an older, smaller library — 5,000 signals four at a time, roughly 2.6 × 10¹³ combinations per simulation. Search a space that large against a fixed history and strategies with excellent backtests are guaranteed to appear whether or not anything real is there. The robustness suite exists because of this, and it reduces the problem rather than removing it: the tests run on the same history the search already mined, so a candidate that survives them has passed a harder filter, not proved an edge.
• Windows only. Windows 8, 10 or 11 with .NET Framework 4.0; Mac users need a virtual machine.
• No trial, so the first time you use it is after paying $1,497.
• It does not trade. Live execution, and every problem that comes with it, belongs to the destination platform.
• A one-person operation: frequent releases, and a single point of failure for a lifetime licence.
• Pricing beyond the lifetime plan is not coherently published, and the store is untidy enough to mislead.

Alternatives

Composer is the other no-code card here and the opposite design: hosted, free to backtest, and it routes the orders itself — but it is US stocks and ETFs on daily bars, with no strategy search. WealthLab is the same Windows desktop shape with a lifetime option, if you would rather write C# than have a search write the rules. QuantConnect or the Python libraries if the result needs to be portable code you own from the start.
