What you learn
Does the rule hold up? How much can it lose? What order would the bot place? Learn to answer those questions with your own data and code.
Illustrative examples of the work you learn to do. Figures shown are sample data.
01 / BACKTEST
Run the same rule across years of history and include the costs that change the result.
02 / MARKET DATA
| date | open | high | low | close |

Connect data, signals, risk checks, and broker orders in one process you can follow from start to finish.
01
You trade and have rules you want to test.
02
You use spreadsheets and need a repeatable process.
03
You can code but market data and execution are new.
