Research methodologyQRD / EVIDENCE SYSTEM / 01-07

Evidence before assertion.

QRD separates exploration from validation, historical evidence from prospective evidence, and an attractive backtest from a strategy that has survived a documented research process.

Read the mandatory standard
01

Hypothesis

State the research question and economic rationale before interpreting results.

02

Experiment

Define the universe, data, signal timing, execution assumptions and complete search space.

03

Walk-forward OOS

Respect chronology. Select and test without leaking future information into model choice.

04

Robustness

Stress costs, parameter neighbourhoods, regimes, data choices and sampling uncertainty.

05

Statistical validation

Use holdouts, Deflated Sharpe Ratio, PBO/CPCV and bootstrap or Monte Carlo where appropriate.

06

Freeze

Lock signal logic, parameters, universe, execution and portfolio rules into a reproducible version.

07

Forward OOS

Track the frozen model prospectively and keep forward evidence separate from historical backtests.

Research discipline

Make the evidence trail
hard to rewrite.

The strongest research system is not the one that produces the smoothest equity curve. It is the one that records what was asked, what was tested, what failed and what remained unchanged after freeze.

Point-in-time data

Record when information became available rather than when it was later stored.

Realistic execution

Costs, spread, slippage, market impact and borrow assumptions belong inside the research design.

Search transparency

Report the entire search space and experiment count, not only the winning configuration.

Visible failure

A failed hypothesis is a legitimate research outcome and should remain part of the evidence trail.

Publication minimum

A technically competent reader should know what happened.

Every QRD paper should disclose enough information to understand what was tested, when decisions were made, how trades were simulated, how many alternatives were searched, which robustness gates were applied, what failed and what limitations remain.

Research governance

When rules change, the version changes.

A frozen strategy should not be retrospectively rewritten. Material changes create a new version so the historical record remains interpretable under the standard that governed it.
