Overview
MySQL Trade Replicator consists of a master script that records trades and a slave script that replicates them. The tool supports volume scaling via multipliers or fixed lot sizes, trade direction inversion, and the ability for a single slave to follow multiple master accounts simultaneously. It manages entry and exit synchronization through database polling, including slippage controls and retry mechanisms for trade execution.
- Cross-broker trade replication via MySQL database intermediary
- Volume scaling with fixed lot or master ratio modes
- Trade direction inversion for contrarian replication
- Multi-master support for following several signal providers
- Automated database table creation and management
