Research workflow
A cluster on evaluating trading ideas honestly before you trust them with capital.
Good research workflow is what prevents a clean backtest from turning into false confidence. These pages focus on the practical checks that narrow the gap between a historical story and a process you would still believe once the market changes.
The goal is not to add ceremony for its own sake. It is to make validation, walk-forward thinking, and paper-trading discipline legible enough that a strategy can survive scrutiny from someone other than its creator.
Questions in this cluster
Each page answers a narrower search-shaped question while staying linked to the broader research theme.
Research process
What is the difference between backtesting and paper trading?
Backtesting asks what would have happened under historical assumptions. Paper trading asks how the strategy behaves now, with today's market conditions, operational quirks, and real-time decision loop.
Research process
Why does out-of-sample matter more than a clean in-sample backtest?
Because a strategy can look elegant on the data it was tuned on and still fail once the market moves beyond that fitting window. Out-of-sample is where the story has to survive without special pleading.
Research process
What is walk-forward testing in trading?
Walk-forward testing repeatedly fits or chooses a strategy on one historical window, evaluates it on the next unseen window, and rolls the process forward so you can see whether the edge survives across multiple market conditions.

How do you compare a backtest against a real baseline?
You compare a backtest against a real baseline by turning the idea into a repeatable decision rule, attaching realistic turnover and risk constraints, and checking whether the workflow still holds up once the flattering assumptions are removed.

What should you validate before you compare a backtest against a real baseline?
The most useful ways to evaluate compare a backtest against a real baseline are the ones that show whether it still works after costs, timing, turnover, and portfolio context are included, not just whether one chart looks cleaner in hindsight.
