Run fully automated Wall Street AI trading strategiesWashington DC insider strategieshedge fund quant strategies

Self-directed US investors who want systematic strategies running in their own brokerage account without writing code. You should be comfortable reading a strategy's rules and accepting that it can lose money. The options strategies assume you understand assignment: a call you sold can take your shares away at its strike, and a put you sold can make you buy 100 shares at its strike.

Alpaca (Alpaca Securities LLC) is an SEC-registered, FINRA/SIPC-member brokerage built specifically for automated and programmatic trading. Alpaca holds custody of your funds and securities and executes strategy orders directly on your account — StreetAI never takes custody of your money.

Yes — Alpaca and Robinhood, and they run different strategies. Other brokers aren't supported yet; email support@street.ai and tell us which one you use.

Alpaca supports the full catalog: long and short stocks, books that run above 1× your account, and options strategies, subject to your account's approvals and buying power.

Robinhood supports long-only stock and ETF strategies, up to 1× your account. It cannot short stocks or run a stock book above 1×, so strategies that reverse a long-only book into shorts cannot run there. A margin-type Robinhood account is required; cash accounts aren't supported.

Options availability depends on the strategy and your account. A Robinhood options strategy must be enabled for your account on StreetAI, and you need the relevant options approval from Robinhood. The Start dialog shows whether your chosen strategy is available on your account and explains any restriction.

On Alpaca, orders that add stock exposure are capped at 3× effective exposure across the account's stock and ETF holdings and opening orders: a dollar in a 3× fund counts three times, and your own stock holdings count too. Option positions and orders are excluded, so this is not a cap on total account risk. The limit never sells anything: an account over it cannot add stock exposure until it is back under. A strategy built to run bigger than that runs smaller live, and the Start dialog tells you so.

Robinhood stock strategies run at no more than 1× your account in stock and ETF notional value; leveraged funds and options can create greater market exposure.

Yes — every strategy starts with a configurable loss floor, usually measured against your account's previous close, with confirmed deposits and withdrawals taken into account. By default, a 4% loss stops new entries while existing positions still exit normally. A confirmed 8% loss triggers a request to close the strategy's positions and stop it, after two separate account checks, at least a minute apart, both confirm the loss.

If cash movements cannot be verified, an apparent breach of the closing threshold pauses new entries while we check, without automatically selling positions. If account data is unreadable, the floor cannot assess the loss. Starting or resuming after a trip can reset the reference value to your account's value at that time.

You can change either level, or switch the floor off, from the Loss floor setting on each strategy in your portfolio. Checks run only while the market is open. The floor cannot act overnight or guarantee a closing price, and losses can exceed the threshold.

It depends on the strategy. Some long-only stock strategies can start from about $500–$1,000 without borrowing. They trade whole shares, so a small account holds fewer names and may skip expensive stocks. Alpaca requires at least $2,000 in equity to use margin or sell short; the smaller starting range does not cover those strategies.

Covered-call, cash-secured-put and collar books need enough shares or collateral for 100-share contracts, so their capital needs can be much higher. Check the strategy's stated capital requirements and the account checks in the Start dialog.

Yes, at Alpaca. Connect an Alpaca paper account: same strategies, same orders, no real money. Switch to a live account whenever you choose. Robinhood has no paper account, so a Robinhood strategy trades real money from the moment you start it.

A trading connection: sign in with your broker, or connect Alpaca using a trading key. We never ask for your brokerage password. We store the connection credentials encrypted with a key held in Google Cloud KMS, and only our own servers decrypt them to run your strategy, show your Alpaca balance or renew your Robinhood sign-in. This connection cannot withdraw or transfer money. While a strategy runs we regularly read your balance, positions and open orders.

When you remove the connection in settings, we stop the strategy and delete its stored trading credentials if no position closures are pending. Otherwise, we keep the connection and ask you to disconnect again after those closures are complete. You can also revoke access at your broker, but that does not itself delete credentials stored here or close positions. Security and audit records may remain as described in our Privacy Policy.

At Alpaca, covered calls and cash-secured puts require Level 1 approval. Buying calls or puts, including a collar's protective put or an options add-on, requires Level 2 approval. See Alpaca's options levels.

At Robinhood, you need the options approval required by the chosen strategy, and that strategy must be enabled for your account on StreetAI. The Start dialog checks availability and account approval. Your broker decides approvals; StreetAI cannot grant them.

StreetAI is completely free while we are in beta. After beta, we will charge a simple, fixed flat monthly subscription fee to deploy and run automated strategies. No assets-under-management (AUM) fees, no cut of your profits, and no selling your order flow — just a transparent flat monthly rate. Your broker's own costs are separate — see the next question.

Anything your broker charges is between you and your broker, set by your agreement with them, and paid by you — StreetAI doesn't set it, collect it, or refund it. Depending on the strategy and your account, that can include:

Margin interest on money you borrow — strategies that run above 1× your account, and short sales, use margin, and brokers generally charge interest on a balance you hold borrowed overnight. Borrow fees on shares sold short, which can be steep on hard-to-borrow names. Options fees: per-contract and regulatory fees on options trades. Commissions and regulatory fees where your broker charges them, and the bid-ask spread that can affect your execution price.

Margin needs a margin account approved by your broker, and margin calls are yours: your broker can sell positions to meet one without asking you or us. Simulation cost assumptions vary by strategy and may not capture what your broker actually charges. Check your broker's fee schedule and margin agreement before you start.

From your portfolio, Pause stops new entries while existing positions continue to exit normally. Stop requests closure of the strategy's positions and stops it. Closing needs an open market and a working trading connection: outside trading hours, or when the trading service is unavailable, positions may remain open until a subsequent market session. Orders can also be delayed or only partly filled.

Revoking broker access is not a closing order and can prevent us from closing anything; you may need to close positions yourself at your broker. We email you when a loss-limit pause or halt occurs.

Yes. Each strategy in your portfolio has a Don’t trade list, next to its Loss floor: up to 50 tickers it will never open or add to. Anything it already holds in those names still exits normally — the list never sells a position on its own. A change reaches a running strategy within about a minute, with no restart. Income (covered call and cash-secured put), collar and Follow strategies don’t take a list, because an option can assign stock and a Follow strategy mirrors a disclosed portfolio.

Orders can be delayed, rejected, partially filled, or missed — by us, by your broker, or by a data provider between us — and we may stop any strategy at any time. Automation doesn't remove the need to monitor your account.

It depends on which part is unavailable. A website outage can leave strategies trading normally. A signal-feed outage can pause new entries while loss controls and scheduled end-of-day closes continue. If the trading service itself is down, it cannot send new orders or close positions; orders already at your broker can still fill.

Your cash and positions remain at your broker. A missed end-of-day close can leave positions open overnight. Check your strategy's status after recovery, since some halts require you to resume it. You can monitor and manage positions directly at your broker throughout.

US stocks, ETFs and supported listed options, during regular market hours (9:30 AM–4 PM ET; shorter sessions on early-close days). Availability at Alpaca and Robinhood depends on the strategy and your account's approvals; the Start dialog shows what your account can run. StreetAI is for US residents.

Strategies that finish the day flat stop opening new positions at 3:45 PM ET (12:30 PM on early-close days) and close what they hold in the last ten minutes of the session, from 3:50 PM ET on a normal day. Strategies built to hold — some daily AI portfolios, price rules that hold for days, and covered-call, cash-secured-put and collar strategies — keep their positions overnight. Each strategy’s description says which kind it is.

Returns labelled simulated in the catalog and Lab are historical replays. AI strategies replay recorded, timestamped calls; options and technical strategies replay their own rules against historical market data. Your connected account's balance and performance come from brokerage data, and are shown separately from these simulations.

AI stock replays charge 2 basis points (bps) of slippage a side. Options replays worsen each option fill by 2% of its premium, with a minimum of $0.01 per share, and apply 2 bps per side to share trades. Those AI and options replays leave out commissions, actual bid-ask spreads, margin interest, borrow costs and taxes. Technical backtests use their own stated cost assumptions, including modelled borrowing and financing costs where applicable. These estimates can differ from what you pay live.

AI strategy replays refresh hourly from 10 AM to 3 PM ET and after the close; options and technical replays refresh after the close. A strategy that replayed well can lose money live.

Yes — up to everything in the account. Many strategies trade leveraged funds, which move several times as far as the market in a day, and an account on margin can lose more than it holds. Many configurations we test lose money and clearing a bar is not a promise about tomorrow. Past results are never a promise about future returns.

No. We are not licensed advisers. StreetAI is not a broker-dealer, not a registered investment adviser, and not your fiduciary. We publish what each strategy did and exactly how it was measured; what you do with your own account is your decision.

Claude Opus (Anthropic), Gemini Flash (Google), GPT Sol (OpenAI), MuseSpark (Meta), Qwen 3.8 (open-weights), and DuckAI, our own fine-tune. They cover a universe of 425 stocks and funds, with new ratings roughly every 30 minutes during the trading day. Directional calls are scored against the following roughly 30 minutes of price movement when prices are available. Grades are published after the close, with grading scheduled at 4:45 PM ET and analyst profile updates at 5:05 PM ET. Report cards are public — hit rate, streaks, biases, best and worst calls.
