Sandbox

The sandbox environment offers users a secure space to explore Studio. It allows users to get a feel for the actual system and test out the API without the risk of submitting live orders. This setup allows users to familiarize themselves with the platform’s capabilities while understanding its functionality in a safe and controlled environment.
In this environment, automatic fills for orders and locate requests are provided to ensure a seamless experience. Fills for market and stop market orders are based on the last trade price, while limit and stop limit orders are filled at their specified limit price.

The market data is not live; it is recorded and serves multiple purposes. In addition to being shown in the UI, it drives the risk and P&L calculations and acts as a reference price for buying power calculations. While the risk calculations use a simplified methodology, they provide users with a realistic simulation of the actual system, though not identical.

While only a subset of symbols has recorded market data, users can submit orders for additional symbols using the API. For these custom symbols, the reference price defaults to 100. These orders do not appear in the UI and are excluded from risk and P&L calculations.

Available symbols with market data include:

• AAPL
• NVDA
• MSFT
• AMZN
• GOOG
• META
• TSLA
• BRK B
• TSM
• AVGO
• WMT
• LLY
• JPM
• V
• UNH
• XOM
• ORCL
• MA
• NVO
• COST
