Build the foundations
Suggested foundations for probability and statistical reasoning and trading research and honest backtests. Specialist prerequisites vary by resource.
Before you read
- Random Variables and Distributions
Read the distributions and expectations used in probabilistic arguments.
- Conditional Expectation
Interpret expectations after information is observed.
- Point-in-Time Data
Use only information available at the simulated decision time.
- Time-Ordered Train, Validation and Test Design
Separate model selection from the final evaluation.
Go further
- Confidence Intervals and Hypothesis Testing
Assess uncertainty rather than treating an estimate as a fact.
- Positions, Trades, Fills and P&L
Reconcile signals, executions, positions and P&L.
- Financing, Borrow and Transaction Costs
Include the costs that can erase a paper strategy.

- Probability for quant interviews
Move from conditioning and expected values to timed problems with a defensible solution.
- From trading ideas to honest backtests
Choose a reproducible strategy, specify the trading rule, and test what remains after costs and estimation uncertainty.
