BeiDou KaiYang
- Experts
- Version: 1.34
- Activations: 5
Beidou·Kaiyang is a Donchian Channel breakout EA. Default timeframe M30, entry period N=18, exit period M=10, optimized for EURUSD and major pairs.
**Core Logic**
- Entry: close above long upper band → buy; close below long lower band → sell.
- H4 Donchian filter: only trade in the direction of the higher timeframe. Two modes: strict breakout or midline direction. Reference bar can be closed or current.
- Exit: intraday touch of short channel — Bid touches short lower for longs, Ask touches short upper for shorts. Faster than close confirmation.
- Initial stop-loss: reverse long channel, placed in the order. Short stop-loss includes current spread by default to keep actual risk aligned.
- Take profit: risk-reward ratio (default 2.0) fixed TP, plus floating-profit fallback that closes when profit target is reached, ensuring exit even if TP is rejected.
- After take profit, EA pauses automatically until manually resumed.
**Martingale**
- Profit close → level resets to 0.
- Loss close → level +1, next risk multiplied by 1.5 (adjustable). Max 5 levels default.
- Level persists in state file. Timestamp prevents double-count on restart. Order comments include level (e.g., L2).
**Risk Management**
- Risk per trade = balance/equity percentage (default 1.0%).
- Risk amount rounded down to highest digit (e.g., 1234 → 1000).
- Minimum lot fallback if calculated lot is too small.
- Cooldown after close (default 600s, can disable).
- Manual pause/resume button. Paused state persists.
- Double-click one-click close-all button with confirmation.
**UI & Chart**
- Dark card-style panel: market, current position, amounts, Donchian channel, H4 filter, martingale risk.
- Chart draws Donchian lines for recent 1000 bars; upper bands same color, lower bands same color, long/short distinguished by width and style.
- Optional horizontal lines and midline.
**Restart & Multi-Symbol**
- State file per symbol + magic number (e.g., QYD_EURUSD_8111111_state.txt).
- On startup: adopts existing positions, deletes pending orders, resets if flat. Corrects martingale level based on last closed trade.
- Recommended: different magic number per symbol.
**Trading Session**
- Start/end time to the minute, cross-day supported (e.g., 22:00–06:00).
- Only restricts new entries; exits are not restricted.
**Risk Warning**
Martingale is high-risk. Consecutive losses can increase risk exponentially. With 5 levels, cumulative drawdown may exceed 20%. Use base risk ≤0.5%, max levels ≤5, and test on demo for 1–2 months before live trading. No guarantee of profit.
