backtrader.timer module¶
Timer Module - Time-based event scheduling.
This module provides the Timer class for scheduling time-based notifications during backtesting. Timers can trigger at specific times, session start/end, or at repeating intervals.
- Constants:
SESSION_TIME: Timer triggers at a specific time. SESSION_START: Timer triggers at session start. SESSION_END: Timer triggers at session end.
示例
Creating a timer that triggers at session start: >>> timer = bt.Timer(when=bt.Timer.SESSION_START, weekdays=[0, 1, 2, 3, 4]) >>> cerebro.add_timer(timer)
- class backtrader.timer.Timer[源代码]¶
-
Timer class for scheduling time-based notifications in backtrader.
Timers can trigger at specific times of day, session boundaries, or at repeating intervals. They can filter by weekdays and monthdays.
- Params:
tid: Timer ID for identification. owner: Owner object of the timer. strats: Whether to notify strategies (default: False). when: When to trigger (time, SESSION_START, or SESSION_END). offset: Time offset for the trigger. repeat: Repeat interval for recurring timers. weekdays: List of weekdays when timer is active (0=Monday, 6=Sunday). weekcarry: Whether to carry over to next weekday if missed. monthdays: List of month days when timer is active. monthcarry: Whether to carry over to next month day if missed. allow: Callback function to allow/disallow timer on specific dates. tzdata: Timezone data for the timer. cheat: Whether timer can execute before broker.
示例
