RESEARCH WORKBENCH

Real observations.
Reproducible experiments.

Read a public reference series, replay it one day at a time, and inspect bounded paper outcomes.

ECB / DAILY REFERENCE SIMULATION ONLY Open pitch

Help and plain-language guide

What this is: VenueForge is a browser-local research workbench. It reads dated European Central Bank (ECB) reference observations and replays them as a paper-only simulation. No money moves and no real orders are sent.

Run a research session

  1. Choose an instrument. Select a currency pair such as EUR / USD, then refresh the official ECB source or load the dated bundled snapshot.
  2. Check the source. Read the observation date, retrieval time, freshness, source URL, digest, chart, and the expandable observed-rate table. The digest is a SHA-256 fingerprint of the source data, not a signature.
  3. Replay observations. Move one day at a time, use the slider, or play the replay. The current rate is a historical reference observation, not a live quote.
  4. Enable the paper simulation. Review the side, whole-EUR quantity, and optional limit reference. “Enable simulation” only enables hypothetical calculations.
  5. Simulate an order. A fill uses the selected daily reference rate. This model has no spread, fees, slippage, queue, liquidity, or historical execution claim.
  6. Review the session. The ledger records simulated outcomes. Rewind, pair changes, source changes, contract changes, and reset clear the affected paper state and leave simulation killed.
  7. Use the scenario tools. Validate and apply the bounded JSON scenario, save one checked scenario on this browser, or export a research report. No account, cloud persistence, database, or real trading service is used.

Plain-language glossary

ECB
European Central Bank, the public source of these daily euro reference rates.
Reference observation
A dated published rate used for research replay; it is not an executable market quote.
Replay
Stepping through the observed dates in order without looking ahead.
Simulated order / fill
A paper calculation recorded by this browser. It never reaches a venue or moves funds.
Spread, fees, slippage, and liquidity
Trading costs and execution limits intentionally omitted from this small model.
Position and equity
Simulated EUR holdings, and simulated cash plus the holdings valued at the current reference rate.
Scenario JSON
Structured text describing bounded simulation settings. It is not FinancialSpec or an operational risk policy.
Digest / hash
A repeatable fingerprint used to identify source or scenario content. It is not proof, a signature, or an authorization.
FinancialSpec
VenueForge’s separate financial protocol specification; this browser MVP does not compile or qualify it.
