TheoryCraft vs TradeStation (2026)
TradeStation routes the order. TheoryCraft proves the strategy first.
TradeStation is a regulated US broker where you write strategies in EasyLanguage and route real orders. It even connects Claude over MCP to place those trades.
That is the execution side of trading. TheoryCraft is the research and validation layer that comes before it. You describe an idea in plain language, an AI assistant writes and runs the backtest as standard, portable Python, and the engine stress-tests the result the way a quant would.
TradeStation keeps your logic inside EasyLanguage, tied to a funded account. TheoryCraft writes standard Python you export and run anywhere, on an open engine you can read and fork.
Prove the edge in TheoryCraft. Route the order in TradeStation once you trust it.

AI on TheoryCraft vs TradeStation
TradeStation has an official MCP connector, and it is real. Through a paid Claude Pro subscription, it lets you connect Claude to your live account to place real orders, with confirmation on each one. That MCP is built for execution.
TheoryCraft's MCP is built for research. You connect Claude, Codex or Cursor to build and run standard, portable Python, and you do it across 26 providers:
- From a brief to a backtest. Describe the idea and the assistant writes the code, runs it, and reads back the results. You can also write the code yourself; the AI is a head start, not a black box.
- Standard, portable Python. Every strategy is readable, exportable Python that runs anywhere, not EasyLanguage tied to TradeStation.
- Your own agent, your own model. Connect Claude, Codex or Cursor over MCP, and either use the model included on the Managed plan or bring your own key across 26 providers.
- Scientific validation. Walk-forward and Monte Carlo are part of the workflow, with the Edge, its Filters and its Risk rules tested on their own.
- Data its US broker lacks. Forex and EU equities are included, alongside US markets.
TradeStation's MCP places real orders. TheoryCraft's MCP runs the research that tells you whether to place them.
Why traders pair TheoryCraft with TradeStation
Research before execution
TradeStation is built to route orders, with EasyLanguage automation and an MCP that places trades. TheoryCraft is the layer before that: you prove the edge with AI-written Python, walk-forward and Monte Carlo, then take a validated strategy to your broker.
Standard, portable Python
EasyLanguage exports as .eld files that only run inside TradeStation. TheoryCraft writes standard Python you read, export and run anywhere, the same code a quant would write by hand.
An open engine and your own AI
TheoryCraft's tick-level engine is open source under Apache-2.0, and you connect your own agent over MCP across 26 LLM providers. TradeStation is a proprietary, hosted brokerage, and its MCP runs on a paid Claude Pro subscription.
Data TradeStation does not bundle
TheoryCraft ships 1,600+ instruments via Dukascopy Bank, covering forex, EU and US equities, metals, commodities and indices. TradeStation bundles data with a funded account, has no spot forex on its US broker, and keeps tick history short.
Stop guessing. Start proving.
Turn an idea into evidence. Build it, backtest it, and see whether the edge is real before you risk capital.
Frequently asked questions
Is TheoryCraft a TradeStation alternative?
They cover different stages. TradeStation is a regulated broker that routes orders; TheoryCraft is the research and validation layer before execution. You prove the edge in TheoryCraft with standard, portable Python and scientific validation, then route the order in TradeStation. Many traders use both.
Does TradeStation support AI or Claude?
Yes. TradeStation has an official MCP connector that, through a paid Claude Pro subscription, lets you connect Claude to your live account to place real orders, with confirmation on each one. It is for execution, not for writing EasyLanguage. TheoryCraft's MCP instead drives standard, portable Python research across 26 providers.
Can I use Python instead of EasyLanguage?
Yes. On TradeStation, strategies are written in EasyLanguage and export as .eld files that only run on TradeStation. TheoryCraft generates real, exportable Python you can run anywhere.
Do I have to use the AI, or can I write the code myself?
Either way. The assistant writes and runs a strategy from a plain-language brief, but every strategy is real Python you can read, edit and write from scratch yourself. TheoryCraft is AI-assisted: the AI drafts the code, it stays standard, portable Python.
Which market data does TheoryCraft include?
TheoryCraft includes 1,600+ instruments via Dukascopy Bank, covering forex, EU and US equities, metals, commodities and indices, with tick-level history. TradeStation bundles data with a funded account, has no spot forex on its US broker, and keeps tick history short.
