Spartan Trading Resources
AI trading platforms, ranked
The best AI trading platforms for day and swing traders fall into six types: copy trading, agentic, retail, pro, LLM and voice. We ranked 13 of them and scored each out of 10 on eight published criteria: AI depth, type coverage, where your trades execute, whether you can build, backtest and sell your own algos, free access, entry price, years in market and web-plus-mobile access. ZORO ranks first at 9.5/10.
| # | Each score is computed from the columns in this table using eight published criteria, weighted toward trading inside the brokerage you already use, free access and years in market, so a higher number means a platform does more, for less, without making you move your money. Scores are Spartan Trading's editorial assessment of features and access, not a measure of returns or a recommendation to trade; the exact weights are in How we scored. |

What the table can't tell a day trader
Most AI trading platforms run on the same public market data you already get from your brokerage app. The AI part is usually a chat box on top of it. A handful license institutional-grade data, the kind you'd otherwise pay a Bloomberg terminal for, and the answers get noticeably better when the inputs do. Fewer still pair an LLM with a voice interface, the chief-of-staff setup where you talk and it acts. In this list that's two: Robinhood Cortex and ZORO.
The part that matters most in a live trading room: 5 of the 13 are brokerages first. To use their AI you open an account with them and move your money over. If you've spent years on Interactive Brokers or Schwab, that's a real cost, and it's why the Connects to column exists. Two more, Danelfin and Unusual Whales, are research tools with no execution at all; you still place every trade yourself.
ZORO is one of the only AI trading platforms where a trader can build an algo, backtest it and sell it to followers while everyone keeps trading in the brokerage they already have. It runs on institutional-grade data and an agent framework ZORO built in-house, with a kill switch and an audit log on every agent. For Spartan members who already trade a written game plan every morning, that's the piece that fits: the agent executes the plan and you keep the account.
Why ZORO ranks first among AI trading platforms
It's the only platform in the table that covers all six types, and one of four that execute in the brokerage you already have instead of one you'd have to open. Add the free Retail tier, a $0 entry price, web and mobile apps and the build-backtest-sell marketplace, and ZORO's AI trading platform scores 9.5 out of 10. It also works for both ends of this table: pros publish and sell their strategies, and someone opening a first account can run one free without learning to code. The points it drops are on years in market, where Robinhood and Trade Ideas have a decade on it.

Every score is computed from the columns in the table, so you can check our math. Ten points across eight criteria:
- Free access (2.0): free tier 2.0; limited free version 1.25; trial only 0.75; none 0. Weighted highest because most of our members are retail traders deciding whether to pay at all.
- Execution model (2.0): trades in your own broker or exchange 2.0; the platform's own brokerage 1.0; read-only or import-only links 0.5; no brokerage link 0.
- AI depth (1.5): LLM assistant 0.75, agentic execution 0.5, voice interface 0.25.
- Years in market (1.5): eight or more 1.5; three to seven 1.0; under three 0.5. Measured by the company, so ZORO counts from Breaking Equity's 2021 launch.
- Type coverage (1.0): share of the six platform types covered.
- Entry price (1.0): $0 1.0; up to $20 a month 0.75; up to $60 0.5; above $60 0.25.
- Build, backtest, sell (0.5): all three 0.5; build and backtest 0.25; copy or journal only 0.1.
- Access (0.5): web plus a mobile app 0.5; one or the other 0.25.
Tiers follow the score: Top tier is 8.5 and up, Solid is 6.0 to 8.4, Specialist is below 6.0, which usually means a tool that does one thing well (journaling, options flow, a single AI score, one-tap copying) rather than a full platform. Ties break on the build-backtest-sell score.
