Define before observing
Write down the mechanism, the target and the conditions that would invalidate the idea before looking for a favorable result.

Algorithmic Research
Ideas deserve a harder test.
An elegant backtest is a question, not an answer. Research becomes more useful when every assumption can be challenged and every result can be reproduced.
The perspective01The perspective
The experiment matters as much as the algorithm.
Every research choice leaves a fingerprint: the universe, the observation window, the parameters and the cost model. A credible process records those choices, tests alternatives, and keeps later evidence separate from earlier decisions.
Protect the experiment
Keep training and evaluation periods distinct. Track trials so that repeated searching is not mistaken for independent evidence.
Design for reality
Account for costs, delayed inputs, missing observations and system failures. The research contract should survive imperfect conditions.
An interactive study
Follow the evidence.
Explore three gates in a research workflow. Each gate asks a different question; none can be replaced by a good-looking return curve.
Selected lens
What would make this idea false?
Define the economic mechanism and a measurable prediction. Record the experiment before seeing the evaluation outcome.

Conceptual workflow. Selecting a stage highlights its role; it does not execute a backtest or connect to a trading system.
02Questions worth asking
Was the information available then?
A historical timestamp is not enough. Publication time and later revisions can change what was actually knowable.
How many ideas were tried?
The best result in a large search may reflect selection. Keep the full experiment history in view.
What happens outside the model?
Latency, turnover and failures belong in the design, rather than appearing as explanations after an experiment disappoints.
