Overview
Gotobi EA Codex aims to capitalize on historical US Dollar demand by opening long positions on specific days of the month, specifically those ending in five or zero. The robot operates on a time-of-day basis, entering and exiting trades at predefined intervals using either Japanese Standard Time or broker server time. Risk management is handled through fixed stop loss and take profit pips, a maximum spread filter, and a limit of one trade per day. The repository does not include a README file.
- Automated Gotobi day detection
- Configurable server or JST timing schedules
- Fixed stop loss and take profit levels
- Maximum spread and deviation filters
- Single daily trade restriction
