Test the setup. Understand the limits.

What a test environment is useful for

A paper or sandbox account lets you observe a setup without placing the same activity in a funded live account. It can help you learn where the controls are, how a strategy entitlement appears and how the connection reports its status.

You can also use it to understand the difference between configuring an allocation, arming execution, disconnecting and attempting to close positions. Operational familiarity is valuable even when the test environment does not match every feature of a live account.

Confirm the correct environment

The documented Alpaca integration has paper and live modes. Webull has sandbox and live environments, while the Public connection is documented as live only. Other account types and testing arrangements depend on the current broker integration and your eligibility.

Before activating anything, confirm the provider, account identifier, environment and credentials shown in your setup. A familiar account name is not enough to establish that it is a test account. Follow the current in-app broker guide.

Do not confuse a simulated fill with a live fill

Test environments can simplify how orders are filled. They may not reproduce market depth, slippage, partial fills, queue position, borrowing availability or all fees. They can also use different permissions and data behaviour from a live brokerage account.

A successful paper order therefore shows that one path worked under those conditions. It does not prove that the same instruction will execute at the same price or even be available in the live account.

Review again before any live activation

Changing from test to live is a separate decision. Recheck the account, strategy selection, allocation and risk action. Make sure you know how to inspect actual broker orders and how to stop future execution.

The getting-started checklist and broker guides can help you organise that review. Test results do not demonstrate suitability or guarantee future profits.
