All ten Kitson Maxxing Trading apps: test, practise and learn on made-up data, your own price files and your own trades and plans.

Every app in the line is education or testing only. Each one does its figures in code on your own computer, sends Anthropic only what it needs (you can see exactly what before anything goes), checks every number Claude Opus 5.5 writes against its own figures, and never tells you what to buy or sell.

The ten apps (bought singly: $530)

1. Trade Journal Coach: review your own trades against your own rules ($49 singly; a run about 12 to 13 cents)

2. Strategy Translator + Backtest Lab: plain English to a tested strategy ($69 singly; about 19 cents for the whole thing)

3. AI Trading Team Sandbox: watch AI agents reason, then see where they went wrong ($49 singly; a run about 11 cents, the Auditor about 11 cents more)

4. Backtest Report Critic: recompute any backtest and check its claims ($49 singly; a run about 9 cents)

5. Options Payoff and Greeks Explainer: see how an options position makes and loses money ($69 singly; a run about 18 cents)

6. Trading Plan and Position-Size Planner: your own rules turned into numbers ($49 singly; a run about 12 cents)

7. Market Replay Paper-Trading Coach: practise decisions with the future hidden ($49 singly; a run about 10 cents)

8. Machine Learning for Trading Lab: why most ML results on prices don't hold up ($49 singly; a run about 9 cents)

9. Risk-of-Ruin Simulator: losing streaks, drawdowns and ruin on your own assumptions ($49 singly; a run about 18 cents)

10. Chart and Indicator Tutor: what indicators show, how they lag and how they are misread ($49 singly; a run about 17 cents)

The run costs are from our own tests on the made-up samples, on our own Anthropic account.

Bought singly, the ten cost $49 x 8 + $69 x 2 = $530. The bundle is $449, $81 less.

What you need

- Free Node.js 18+ (Windows, Mac or Linux).

- Your own Anthropic account and API key, with a little credit. A Claude chat subscription does not include API access. One key works for all ten apps.

- Each app shows the cost before every run, and you set a limit. Asking for a change is charged as another run.

You pay Anthropic directly for what you use, on top of the price of the bundle.

Educational only. Tests, simulations and explanations on historical, made-up or your own data. Every probability in these apps is a model or simulation output on your own inputs, not a forecast, and historical counts describe the past only. Past or simulated results do not predict future results. Not financial advice. No app recommends any trade, and no app ever places trades. Trading involves risk of loss. If we can't get an app running for you, email kit376351@gmail.com within 14 days for a refund of that app's share of the bundle price ($44.90 for each app we can't get running).
