1. Simulated live trading

Dear user, welcome to read the qteasy simulated live trading document.

What is simulated live trading? Backtesting is using historical data to “fast-forward” and validate a strategy; simulated live trading (configured with mode=0) allows the strategy to run in real time—calculating signals, placing orders, and logging according to a schedule, just like actually monitoring the market. However, the execution is usually completed by a local simulated brokerage, without involving real funds. This allows you to experience the path “before backtesting and before live trading” before investing real money, and to use the same set of strategy logic as backtesting, reducing the discrepancy between “great backtesting, distorted live trading.”

**If you have not yet completed backtesting or are using qteasy for the first time, it is recommended that you read QTEASY Quick Start Guide and Build your first strategy before returning to this module.

This module helps you answer:

  • How to configure and start a live trading simulation

  • Risk control and the entire process from order submission to completion.

  • Where are the logs and artifacts located? What should be checked first when a problem occurs?

  • (Advanced) How to extend brokerage compatibility and how to perform maintenance smoke analysis.
