Each historical window produces final ensemble quantiles from prior real bars only. Entry blocks use requested forecast quantiles; quantile/percentage targets and trailing stops use completed observed closes, with fills at the next observed bar. No live orders. Requires forecast.create and monthly allowance; event-market display quotes are not executable bids or asks. ## OpenAPI ````yaml https://quantura.studio/api/openapi.json post /backtests openapi: 3.1.0 info: title: Quantura Forecast Intelligence API version: 1.0.0 description: >- Versioned access to Quantura forecasts, collaborator-aware workspaces, screeners, datasets, and provenance metadata. contact: name: Quantura url: https://quantura.studio/contact license: name: Quantura API Terms url: https://quantura.studio/terms servers: - url: https://quantura.studio/api/v1 security: - bearerAuth: [] tags: - name: Access description: Identity, token scopes, plans, and effective workspace access. - name: Workspaces description: Resources are authorized against current membership on every request. - name: Uploaded CSVs description: Workspace-isolated CSV metadata, organization, and authorized exports. - name: Datasets description: Licensing-aware catalog and schema metadata. - name: Forecasts description: Prospective forecasts and immutable probability trajectories. - name: Ensemble Forecasts description: >- Asynchronous probabilistic time-series ensemble jobs and reproducible presets. - name: Backtests description: >- Asynchronous point-in-time ensemble-quantile simulations and versioned strategy exports; never live order execution. paths: /backtests: post: tags: - Backtests summary: >- Queue a Point-in-Time Quantile Forecast Backtest for an Authorized Workspace description: >- Queues a durable worker.
