Build an AI trading bot for US stocks with your own coding agent.
Super Algo Kit helps you build an AI trading bot for US stocks, ETFs, options and futures inside your own coding agent. Its US market pack holds dated rules, fees and session calendars, with cards for Alpaca, Interactive Brokers and Databento. The kit interviews you, tests the idea with costs and runs it on paper first. Live trading starts only when you type the authorize command.

Paper first
Build for this market, paper first.
Super Algo Kit runs inside the coding agent you already use. It interviews you, writes the spec with pass marks set first, then builds, backtests and paper-tests. Real money starts only when you type the authorize command.
The plan, step by step
Tick them off as you go.
What can you build for US markets?
Describe the idea in plain words. The kit turns it into a bot, a scanner or a risk tool for US equities, ETFs, options or futures.
Order work starts from the Alpaca and Interactive Brokers cards, and Databento covers live and historical data. The broker adapter records each broker's token lifetime and never blindly resends an order whose outcome is unknown.
Which US rules matter for an algo trading bot?
This summary uses FINRA, SEC and CFTC sources read on 29 September 2026. It is not legal advice, so confirm anything that matters with your broker or a qualified professional.
In the kit's reading, a retail individual running an algorithm on their own broker account needs no US registration. Selling signals, managing other people's accounts or running a bot for them can require CFTC, NFA or SEC registration.
- Since 4 June 2026, intraday margin replaces day-trade counts, and brokers may phase it in until 20 October 2027.
- 2,000 USD remains the minimum equity for margin trading, and brokers may ask for more.
- Use only the broker's documented API, and never script a login the broker has not documented.
- The kit refuses to build spoofing, layering, wash trades or marking the close.
Which costs and sessions does the US pack model?
Backtests use dated fees. The SEC Section 31 fee is 20.60 USD per million dollars sold from 4 April 2026. FINRA's 2026 trading activity fee is 0.000195 USD per share sold, up to 9.79 USD a trade. Commissions stay estimates until you supply your broker's schedule.
The core session runs 09:30 to 16:00 Eastern Time. From 6 December 2026, Nasdaq trades overnight and late trades carry the next trade date. Holiday lists are stored as data with year-rollover tests.
How do you paper trade a US trading bot?
Alpaca offers paper accounts on a separate host with separate keys. Interactive Brokers has a paper login on separate ports, reported to need a funded live account.
Paper fills are not live fills, so every paper report names its data feed and fill model. Live trading stays off until you type the authorize command.
Before you rely on it
Rules and risks to respect.
- The kit found no US regulator loss rate for retail algo traders, so it will not invent one.
- Code that checks day-trade counts breaks under the 2026 intraday margin rules.
- Session logic that treats the calendar date as the trade date breaks on 6 December 2026.
- Extended and overnight hours are thin and limit-only, so never backtest those fills at the close.
- Broker tokens expire on different clocks (reported), so a long-running bot needs refresh and alerts.
FAQ
United States: questions.
Can I build an AI trading bot for US stocks without coding?
Yes. Super Algo Kit asks plain questions one at a time inside your coding agent, then writes real code in your project. You approve the brief, the spec and the risk limits yourself, and paper trading comes first.
Is algorithmic trading legal in the US?
The kit's US pack, checked on 29 September 2026, finds no registration requirement for a retail individual running an algorithm on their own account. That is the kit's reading, not legal advice. Selling signals or trading for others can require CFTC, NFA or SEC registration.
Do I still need 25,000 USD to day trade in the US?
FINRA Regulatory Notice 26-10 says the pattern day trader rule and its 25,000 USD minimum were replaced on 4 June 2026. An intraday margin standard applies instead, and firms may phase it in until 20 October 2027. Check your broker's current rules.
Which US brokers does Super Algo Kit work with?
The US pack has cards for Alpaca and Interactive Brokers, plus the Databento data feed. It also lists other retail APIs, such as Tradier and Webull, without cards. Names are used only to say the kit works with them.
Can I paper trade a US stock trading bot first?
Yes, and Super Algo Kit requires it. Alpaca paper accounts use a separate host and keys, and the kit also has its own paper broker. The paper run must pass before any live step.
