# Orchestrator Optimizer Interface

## Context
### Assumptions
* REST API in Optimizer
* Optimizer is stateless (but holds internal in-memory DB)
* Optimizer is a single Docker Image

### Discussion JKU-SWISS

### Open Questions
* how does the Orchestrator provide data to Optimizer?
* send all data for an optimization at once, or
* continously send data and at certain times trigger optimization
* how to provide Equity Monitoring input?
* as part of IF when sending data to Orchestrator, or
* through access to DB from FZAG
