许多交易者在亏损区间本能平仓，却忽略了反向加仓构建恢复区可能把浮亏转平。但马丁格尔式加量若缺明确风控，保证金螺旋会迅速吞噬账户。本篇作为系列终章，把前两层概念压进可执行的MQL5代码与回测结论。

RSI 区域模型的初始化骨架

这段代码搭了一个基于 RSI 的 Zone 交易 EA 底子，先把常量和全局变量定清楚，再在 OnInit 里挂 RSI 句柄。RSI 周期写死为 14、价格源用收盘价，超买线 70、超卖线 30，属于 MT5 里最常规的默认值组合。宏 ZONE_T_L 定义成字符串 "ZTL"，用来给目标低位 Zone 线做标识；随后 #include <Trade/Trade.mqh> 并实例化 CTrade obj_trade，后续下单都走这个对象。zoneRange 与 zoneTarget 在 OnTick 中分别设为 200 点和 400 点（乘 _Point），也就是在常规品种上约 20 点和 40 点的区间带宽。 OnInit 只做一件事：rsi_handle = iRSI(_Symbol, PERIOD_CURRENT, 14, PRICE_CLOSE)，返回 INIT_SUCCEEDED。OnDeinit 里用 IndicatorRelease 释放句柄、ArrayFree 清空 rsiData，避免指标句柄泄漏。开 MT5 新建 EA 把这段贴进编辑器，编译后能在初始化日志看到无报错即说明骨架可用。外汇与贵金属杠杆高，这类未完结逻辑仅作结构验证，实盘前须自测。

◍ 价格越界即清仓与加倍 recovery 的逻辑

这段控制逻辑干两件事：当 bid 跑出目标区就全平并重置，当 bid 落在 zone 内则按方向补 recovery 单。外汇与贵金属杠杆高，这类自动加倍仓位在极端跳空时可能瞬间放大回撤，务必先在策略测试器跑历史数据。越界判定依赖 zoneTargetHigh 和 zoneTargetLow 同时大于 0。一旦 bid 大于 High 或小于 Low，先平当前符号仓位、删画图，再用 PositionTotal 倒序循环按 ticket 逐个平掉剩余持仓，最后把 zone 与方向变量全部归零。在 zone 有效的前提下，recovery_lot 会被 NormalizeDouble 限制到 2 位小数。若 bid 上破 zoneHigh 且买未完成（或上次为空），就 Buy(lots_Rec)，并把 lastDirection 置 1、recovery_lot 乘 2、isBuyDone 置真；若下破 zoneLow 且卖未完成（或上次为多）则反向操作。每次触发 recovery 手数翻倍，连续 4 次后手数可能为初始的 16 倍，这种几何增长倾向在震荡市快速吞噬保证金。别把 zone 边界当绝对安全垫 MT5 实时tick与回测撮合不同，zoneTarget 若由前一根K线算得，遇数据缺口可能跳过平仓条件，建议手动打印 bid 与 zone 值验证触发顺序。

「RSI 反转区的挂单区间画法」

这段逻辑跑在 EA 的 OnTick 里，先处理上一笔 recovery 的方向标记与手数翻倍：若上一次是卖，则 lastDirection 置 -1，recovery_lot 乘 2，并把 isSellDone 标 true、isBuyDone 复位。随后用 iBars 抓当前周期 K 线数，totalBars 没变就直接 return，避免同根 bar 重复触发；PositionsTotal() 大于 0 也退出，保证同时只跑一单。真正进场看 RSI 穿越：CopyBuffer 取缓冲 0 的最近两根（索引 1 与 0），当 rsiData[1] < overSoldLevel 且 rsiData[0] > overSoldLevel，判定超卖反弹，obj_trade.Buy(0.01) 以 0.01 手试多。单子成交后按开价画四条 zone 线：zoneHigh 取开单价，zoneLow = zoneHigh - zoneRange，目标上下沿各加减 zoneTarget，分别用绿/红/蓝画线。lastDirection 置 1，recovery_lot 初始化为 0.02，isBuyDone 标 true。外汇与贵金属波动剧烈，这种 zone 反转策略回测胜率随参数漂移明显，实盘前务必在 MT5 用历史数据验证 overSoldLevel 与 zoneRange 的敏感性。

RSI 超买反转后的卖单与区域画线

当 RSI 前一根柱线高于超买阈值、当前柱线跌破该阈值时，脚本判定为超买回落信号，直接以 0.01 手抛出空单。外汇与贵金属杠杆品种波动剧烈，这类信号仅代表概率性反转倾向，实盘须自行评估穿仓风险。成交后代码通过 PositionSelectByTicket 抓取开盘价，并据此用 NormalizeDouble 按品种小数位推算 zoneLow、zoneHigh（加 zoneRange）、zoneTargetHigh（再加 zoneTarget）、zoneTargetLow（减 zoneTarget）四条边界。随后 drawZoneLevel 以不同颜色宽度把边界画成水平线：红绿为基准区，蓝色 3 像素为目标区。 lastDirection 置为 -1，recovery_lot 初始化为 0.02（0.01 翻倍），isSellDone 置真、isBuyDone 复位。这意味着后续若价格回到区域并触发 recovery 逻辑，加仓手数会从双倍起跳。 drawZoneLevel 本身只是薄封装：ObjectCreate 建 OBJ_HLINE，再设颜色与线宽。想改视觉只需动 clr 与 width 参数，不必碰主逻辑。

◍ 清场旧标记再画新区

在 MT5 的 EA 循环里，每次重算前必须先把上一根 K 线留下的区间线删掉，否则图表会被历史对象堆满，也干扰后续 Zone 的重新定位。上面四行就是干这件事的：ZONE_H 与 ZONE_L 是现价波动区的上下边界，ZONE_T_H 与 ZONE_T_L 则是目标延伸区的上下边界，全部挂在图表子窗口 0 上。具体拆解：ObjectDelete(0, ZONE_H) 删除主波动区上沿；ObjectDelete(0, ZONE_L) 删除主波动区下沿；ObjectDelete(0, ZONE_T_H) 删除目标区上沿；ObjectDelete(0, ZONE_T_L) 删除目标区下沿。四个调用都不带返回值判断，属于测试代码里的粗暴清场，实盘若担心对象不存在报错可加 ObjectFind 前置。把这段塞进 OnTick 或 OnCalculate 的开头，跑策略测试器时你会看到：每根新 K 线生成前旧线消失，图表始终只保留当前 Zone。外汇与贵金属杠杆高，这类对象管理只是防视觉污染的底活，不涉及任何方向判断。

「画得少，看得清」

这套区间恢复马丁格尔的 MQL5 骨架已经铺完：从基础定义到 EA 主体，再到附件里 9.7 KB 的 Zone_Recovery.mq5 实例，你能直接拖进 MT5 编译跑通。它本质是一套仓位管理框架，不是独立进场策略，实盘前最好先接一个区间退出逻辑，否则裸跑恢复单在贵金属跳空时容易把浮亏拖大。外汇和贵金属杠杆高、滑点猛，附件代码只帮你跨过「会自动补单」这道门槛，不代表任何未来收益。把示例里的步长、网格间距按你自己的品种波动率改两行，比照抄全文更有用。剩下要做的就是把这套骨架接进你现有的信号过滤，让恢复单只在概率倾斜时才触发。代码能跑只是起点，参数空间得你自己用历史数据去碾。

常见问题

区域恢复以预设亏损区间为触发，反向单量按倍数扩张并对冲首单，目标是在回归时整体持平；普通网格多按固定间距无明确恢复边界，风险轮廓更松散。

可在EA全局变量设MaxRecoveryLevels，每开一层反向单计数加一，达到上限即停止加仓并告警，避免保证金失控。

小布盯盘品种页支持自定义指标与EA输出字段，把恢复区边界和层数推送到面板，就能在盯盘时看到系统所处阶段，不替代你决策。

恢复单集中在反转点附近，滑点可能使均价下降不及预期，实盘盈利概率倾向低于回测，外汇贵金属属高风险需放大容差再评估。

因持仓量指数增长带来保证金陡升，若市场长期单边，恢复区不回归则爆仓概率高，需严密计划与仓位纪律。
