## At a glance

A useful simulation tests a specific order against explicit market evidence. It must distinguish filled and unfilled quantity, show costs and avoid presenting a snapshot calculation as a real venue fill.

## Start with a current analysis

Select a completed BTC or ETH analysis with unexpired evidence. Choose direction, quantity and limit price yourself. The language model does not choose or authorize a real order for you.

## Inspect the executable side and costs

A simulated buy consumes available ask levels up to its limit; a sell uses bid levels. Returned depth can produce a partial fill. Inspect the applied fee and the remaining quantity. A one-snapshot simulation does not establish queue position or future funding charges.

## Use the result to improve the question

Compare the simulated execution with the original limit and explain any unfilled portion. If the source expires, obtain a new analysis instead of treating the old book as live. Simulated results are neither returns forecasts nor trading capital; no real order is sent by this workflow.

## Start small, keep your budget visible

When a trial campaign is active, eligible verified accounts can claim up to $0.50 in service allowance for at most three analysis admissions, expiring within seven days. The workspace shows the actual offer and cost cap before use. Add $10 or $20 of Credits only through an enabled checkout; applicable tax is shown there. Credits cover CatalystDesk analysis and model use, not wallet funding or trading capital. After reviewing a simulation, a separately enabled Testnet flow may let you review and sign each exact order in your wallet; this is not live-market access.

## Inspect a structured sample

Illustrative workflow, not market data or a complete API response

Illustrative workflow only. No source data, private model parameters or execution logic are included.

```json
{
  "example": "illustrative workflow only",
  "question": "What could change this market assessment?",
  "evidence": "Source context and missing information are identified.",
  "decision_state": "Human review required",
  "limitations": "No current market observation or execution instruction."
}
```

## Start with the service you can verify

The private workspace, when enabled, shows the current service status, per-analysis cost limit and your available allowance before you submit a task. Email verification is required. No ChatGPT or Claude account, model API key, wallet deposit or coding is needed for the hosted analysis flow. This guide does not activate the service or promise a free allowance. Real trading is not available in this flow.
