**Beidou Tianquan EA – MT4 Expert Advisor**

Beidou Tianquan EA is a professional MT4 expert advisor that combines MACD zone analysis with SAR reversal confirmation. It first identifies trend zones using MACD: a golden cross above the zero line defines a long zone, while a death cross below zero defines a short zone. Within a valid zone, any SAR reversal in the same direction triggers an entry. This dual confirmation filters out counter-trend trades. The EA supports breakout pending orders (BUY STOP / SELL STOP) or market execution. If the breakout already occurred, it can automatically enter at market. Pending orders are deleted when SAR reverses. A loose mode allows immediate entry on signal candle close; strict mode requires breaking the K0 extreme.

Risk management uses a unique equity floor rounding (e.g., 2320 becomes 2000) to calculate position size through a nine-step lot calculation. Risk per trade is a percentage of equity or balance. Martin addition is wave-based: after a losing wave, risk multiplies by 1.5 (configurable) up to 5 levels; after a winning wave, the level resets to zero. A hard 50% risk cap prevents blow-ups. The EA also supports two-batch take profit with configurable RR multiples (default 2.0 and 0.0, meaning single batch at 100% close). A 100% first batch closes the entire position. If TP2 is zero, the order’s TP defaults to TP1 to avoid platform rejection.

Stop loss follows SAR dynamically. For short positions, spread is added to the stop price. SAR reversal also closes opposite positions. After a profitable wave, the EA pauses trading until next day 00:00, then automatically resets the Martin level. During pause, existing positions and orders are still managed. Time filter supports hour+minute and overnight sessions (e.g., 22:30–03:15). A cooldown after close is optional.

The EA fully supports restart takeover: it reconnects to its own orders by magic number and restores Martin level, wave state, and pause status from global variables. If orders were closed while the EA was off, it performs a catch-up settlement on startup.

The UI is a dark-themed Chinese panel showing SAR/MACD status, MACD zone, bid/ask, spread, floating P/L, TP/SL amounts, Martin level, and trading status. It includes an auto-trading toggle and a one-click close-all button with double confirmation. All drawing objects use a unified prefix and are auto-cleaned. Order comments include direction and Martin level.

Parameters are organized in seven Chinese-labeled sections: Basic, Indicators, Entry, Risk, Martin, Pause, TP/SL, Time, and Panel. The EA uses no DLLs or web requests. Recommended for EURUSD, GBPUSD, XAUUSD on M15–H1, ECN accounts, minimum $1000.
