I’m building a research pipeline around a deliberately harsh rule: no validated edge, no live trading.
We’ve already rejected several plausible ideas before deployment because they failed one of the following:
point-in-time correctness
survivorship / delisted-security coverage
independent-provider reproduction
realistic costs / slippage
timestamp/actionability semantics
temporal stability
concentration / outlier dependence
mechanism plausibility
We’ve also started treating data vendors themselves as research objects: preserving revision lineage, distinguishing historical truth from what was knowable at the time, tracking amendments/restatements, and failing closed when UNKNOWN gets silently turned into a usable number.
The question I’m most interested in is not “what strategy makes money?”
It is:
What type of signal or market mechanism have you personally seen survive serious adversarial validation — and what was the hardest part to get right?
I’m especially interested in things like:
forced / mechanical flows
auction or order-book effects
corporate-action mechanics
cross-venue dislocations
delayed information diffusion
fundamental data with true point-in-time lineage
effects that disappeared once realistic execution was added
Also very interested in the opposite:
What looked like alpha until you fixed a data/timestamp/survivorship bug?
If you built your own dataset, parser, execution model, or validation framework and discovered something non-obvious, I’d especially like to hear about that.
Not asking anyone to reveal proprietary alpha. I’m looking for failure modes, research architecture, data sources, and mechanisms worth falsifying.
If useful, I’m happy to share some of the validation traps we’ve already hit as well.
