Bridging the Backtest-to-Live Gap
Why live promotion should be a controlled workflow with repeatable evidence, explicit assumptions, and scoped operating authority.
Backtests do not deploy themselves
The backtest-to-live gap is rarely one single flaw. It is usually a bundle of data assumptions, execution assumptions, market friction, workflow drift, and incomplete review. A clean research chart can still fail when it enters a different operating context.
AlphaSwarm narrows that gap by making promotion explicit. A strategy moves through states with evidence attached, not through informal handoff.
The promotion packet
A promotion packet should answer a few concrete questions:
- Which datasets and transformations produced the result?
- Which assumptions changed between research and paper trading?
- What limits, kill-switches, and rollback paths apply?
- Who approved the next authority scope?
- What evidence should block or reverse promotion?
This packet gives risk and platform teams the same operating object as the researcher, reducing translation loss.
Controlled does not mean slow
Good gates should remove ambiguity, not add ceremony. When the evidence is complete and the policy allows the action, promotion can move quickly. When the evidence is incomplete, the system should stop clearly and explain why.
