Best Claude use cases for finance & trading

Non-developers have an agent build, backtest and run a trading strategy; claimed results are unverified.

1. Explain the market and the strategy idea in plain language; the author started with zero technical background.
2. Have the agent backtest the strategy (Fable 5 was used for backtesting and building).
3. Check the backtest for bugs. A separate dev.to write-up found its own backtest had bugs that inflated results.

Tired of pasting numbers, a builder made an MCP server for ~8,200 NSE and BSE stocks so Claude stops inventing P/Es.

1. Build an MCP server over the exchange data you need (here all NSE + BSE stocks).
2. Connect it to Claude so it pulls numbers instead of recalling them.
