Learn the market

Try it before you buy it.

New to trading? You're in the right place. CTbot lets you see how a strategy would have done before you put a dollar in, then practice with paper money while the market moves for real.

  • BacktestSee how a strategy did over 3, 6 and 12 months, or all the way back to 2010, with a crash test back to 1999
  • CompareLine it up against the S&P 500 and the Nasdaq-100
  • ExploreLive prices and stock charts straight from your own Robinhood account
  • PracticePaper money, real prices. No real money at risk.

How it works

Set it up once. Then it runs on its own.

Pick a strategy, choose how much to put in, and set your limits. The bot checks the market every few minutes and handles the rest.

  • 1. ConnectLink Robinhood. Add a Claude key if you want AI to double-check trades
  • 2. DiscoverBrowse strategies with past returns, for clear insights
  • 3. InvestPick an amount, a max loss and a profit target
  • 4. RelaxSee what you own, its gain and its stop-loss at a glance. Stop any time

Strategies

Simple ideas, clearly explained.

No jargon. Each strategy tells you what it does, how risky it is and how long it usually holds. Open one for its chart, its rules and its paper record so far.

  • TrendRide the Nasdaq-100 up, step aside when it turns down
  • DipsBuy index funds after a sharp drop
  • CalendarOwn the S&P 500 around the turn of each month
  • Day tradesMorning breakouts, with AI checking each one

You set the max loss. The bot also has hard rules of its own that no AI can override.

  • ProfitLocks in gains at your target
  • DailyPauses for the day after a bad day

The small print

Your money, your risk.

CTbot is free, open-source software, provided as is with no warranty. It isn't investment advice, and we aren't a broker or an adviser. Trading can lose money, including everything you put in, and past results, including backtests, don't predict future ones.

You can use it with paper or real accounts through Robinhood, and anyone can change the code. Either way, all of the risk is yours, not the app maker's. You must be 18 or older and follow the rules of every service you connect.

CTbot isn't affiliated with or endorsed by Robinhood, Anthropic or Collective2.
