The public channel now contains multiple long-form research lessons. Videos stay optional; the written concepts and methods remain the durable explanation.
Use the video for path-resampling intuition. Use the Method and How-To for assumptions, preserved information, limitations, and interpretation.
The player is not initialized until you choose to load it. The complete written path remains usable without YouTube.
These are the long-form videos currently visible on the TraderCockpit channel.
Why a selected winner must be interpreted in the context of how many alternatives were tried.
Holdout · 5:48Why the untouched sample loses its role when it repeatedly feeds development decisions.
Walk-forward · 5:50Use ordered folds to examine whether fitted choices survive repeated evaluation windows.
Market periods · 6:11Why historical behavior should be examined across changing conditions rather than one aggregate result.
Out-of-sample · 4:21A visual explanation of the development/evaluation information boundary.
Monte Carlo · 7:08Use alternative path orderings to inspect path dependence under an explicit resampling rule.
The channel already exposes two playlists that can be used as durable lesson collections.
Move from visual intuition to the written assumptions and task sequence.
Holdouts, selection bias, drawdown, regimes, distributions, and more.
