◍ EA 参数骨架与订单区块识别配置

在 MT5 里从模板新建 EA 时，只勾选 OnTradeTransaction 事件就够了，其余定时器、Tick 事件先留空，避免无谓开销。随后要定义一套与订单区块指标对齐的参数，让 EA 能独立识别并绘制区块矩形。 先落通用参数：Magic 设 545244 用于区分其他策略订单；timeframe_order_block 默认 PERIOD_M5 决定区块检测周期；Rango_universal_busqueda=500 表示向历史回看 500 根 K 线寻找潜在区块。Witdth_order_block=1 控制矩形边框粗细，Back_order_block 与 Fill_order_block 开关背景和填充，涨跌区块分别用 clrRed / clrGreen。 止盈止损有两种算法，由枚举 ENUM_TP_SL_STYLE 切换：ATR 模式用 Atr_Multiplier_1=1.5、Atr_Multiplier_2=2.0 乘波动率；POINT 模式直接读 TP_POINT 与 SL_POINT，默认都是 1000 点。手数方面 Lote_Type 默认 Dinamico，固定手数时才用 lote=0.1。 下面这段代码就是上述参数的 MQL5 声明，注意 sinput group 仅作面板分组、不进优化。外汇与贵金属杠杆高，参数回看范围过大会拖慢 MT5 每次报价的计算，实盘前建议先缩小 Rango_universal_busqueda 到 200 测帧率。

「EA 风控参数的分组输入逻辑」

这段 MQL5 输入段把账户风控拆成了几组独立开关：先选风险模式（个人户 or Prop Firm），再决定手数怎么算，后面紧跟 ML / MWL / MDL 三组最大亏损限额。 ML、MWL、MDL 三组都用了同样的字段结构：percentage_or_money_xxx_input 填 0 即不启用该限额；mode_calculation_xxx 选按百分比还是金额；applied_percentages_xxx 指定百分比基于余额还是净值。外汇与贵金属杠杆高，实盘前务必确认这三组限额不会在同一笔回撤里叠加击穿账户。 GMLPO 是单笔总亏损上限，mode_gmlpo 给了三种动态模式枚举。DYNAMIC_GMLPO_FULL_CUSTOM 下用 str_percentages_to_be_reviewed="2,5,7,9" 和 str_percentages_to_apply="1,0.7,0.5,0.33" 做阈值联动：权益跌破 2% 阈值后，后续单笔风险自动降到原比例的 1，跌破 5% 降到 0.7，以此类推。revision_type_gmlpo 控制是平仓时还是每个 tick 检查，默认平仓时检查更省算力。 开 MT5 把这段代码贴进 EA 输入区，改 prop_firm_balance=1000 与百分比串，就能直接验证动态降险是否在回测里按预期触发。

阶梯式回撤触发的风险参数与OB捕捉设定

这段输入参数把「账户回撤深度」和「单笔风险百分比」绑成了一条阶梯曲线。当净值回撤触及 2%、5%、7%、9% 这四个阈值时，GMLPO 风险系数会分别从基准被改写成 1.0%、0.7%、0.5%、0.33%——越亏越收手，逻辑上倾向降低连亏放大。 外汇与贵金属属高杠杆品种，这类自动降险参数只是概率层面的缓冲，不保证避免爆仓。MDP（单日最大盈利）模块默认严格模式开启，percentage_or_money_mdp_input 设为 0 表示暂不限制日内利润封顶，交易者可按自己资金曲线手动填百分比或金额。 交易时段被钉在 16:30 至 18:00（服务器时），Order Block 逻辑跑在 M5 周期，Magic 号固定 545244。OB 搜索跨度给到 500 根 K 线，块宽 1 根，允许回画与填充，熊块标红。开 MT5 把这段直接贴进 EA 输入区，改 Rango_universal_busqueda 到 200 看 OB 识别密度变化，是验证参数敏感度的快办法。

◍ EA 参数面板里的风控与止损逻辑

这段输入变量定义了 MT5 EA 在加载时的外部配置，核心落在订单块颜色、止盈止损算法和三层风控阈值。看懂这些 input/sinput 分组，你才能在策略测试器里不盲调。

注意 Atr_Multiplier_1=1.5 与 Atr_Multiplier_2=2.0 只在 tp_sl_style 切到 ATR 时生效；若保持 POINT，则 TP_POINT/SL_POINT 的 1000 点会直接覆盖。外汇与贵金属杠杆高，1000 点止损在黄金上可能对应数十美元浮亏，开实盘前先用策略测试器跑一遍。 动态 GMLPO 的 str_percentages_to_be_reviewed 写了 "2,5,7,9"，意思是权益较余额回撤到这些百分比时，后续新单的风险档位会逐级收紧。这种机制倾向降低连亏扩张的概率，但是否有效取决于行情波动结构，需你用历史数据自行验证。

「GMLPO 动态降险与时段参数的实盘接法」

这段输入参数定义了 GMLPO 策略在净值回撤时逐级收缩风险的机制。核心思路是：当账户权益较初始余额下跌到特定百分比阈值以下，后续订单的手数风险比例自动调低，而不是死扛原始仓位。 str_percentages_to_apply 默认给的是 "1,0.7,0.5,0.33"，对应四级风险档位。inp_balance_percentage_to_activate_the_risk_1 到 _4 分别是 2.0、5.0、7.0、9.0，意思是权益比初始余额低 2% 触发第一档（风险降到 1.0），低 5% 触发第二档（0.7），低 7% 第三档（0.5），低 9% 第四档（0.33）。若两个相关参数都填 0，则不使用动态风险，按原比例跑。 最大日盈利（MDP）模块里 percentage_or_money_mdp_input 设为 0 即不限制；非 0 时按 Balance 或 Equity 计算，mode_calculation_mdp 选 percentage 就以百分比封顶。外汇与贵金属波动剧烈，这类自动降险只能降低概率性爆仓风险，不保证不亏。 交易时段由 hora_inicio=16、min_inicio=30、hora_fin=18、min_fin=0 锁死，只在 16:30–18:00 之间下单。你打开 MT5 把这几行贴进 EA 输入区，改改百分比和时段，就能验证自己的经纪商点差下触发逻辑是否如预期。

EA 全局变量的落地声明

把风险与下单逻辑收口到全局变量，是这套 EA 跑起来的前提。我们直接引自己写的 Risk_Management.mqh，而不是调用平台默认风控，这样仓位计算能按 prop_firm_balance 与 risk_mode 走自定义规则。 CTrade 负责发单，CRiskManagemet 的实例在构造时就要喂入 mdp_is_strict、get_mode、Magic、risk_mode、prop_firm_balance 五个参数，顺序错一个就会编译报错。 指标句柄分两个：order_block_indicator_handle 接订单区块，hanlde_ma 接 EMA；注意原文把 handle 拼成了 hanlde_ma，复制代码时最好顺手改回，不然后期维护容易看走眼。 tp1/tp2/sl1/sl2 四个 double 数组用来承接指标缓冲区的止盈止损价，日线周线和订单区块周期的收盘时间戳则落在 TiempoBarraApertua、TiempoBarraApertua_1、prev_vela 三个 datetime 变量上。 布尔量 opera 初始为 true，用来在浮亏触限后一键禁交易；start_sesion 与 end_sesion 框定信号扫描的时段。外汇与贵金属杠杆高，这类全局开关最好在策略测试器里先跑几周 tick 数据验证再上实盘。

常见问题

把风控拆成「订单区块识别」「阶梯回撤触发」「时段降险」三组独立输入块，每组只暴露相关字段，调参时按块改就不会串。
在时段参数里给亚洲/欧洲/美洲盘分别设风险系数，GMLPO 按当前时段读取系数动态乘到基础仓位上，无需手动切。
可以，把 EA 参数面板截图或导出给小布，它会按订单区块、回撤阶梯、时段降险三块比对，标出缺失或冲突项。
回撤阈值用收盘价确认而非即时价，且每级间隔设 1.5% 以上，并加最小持仓时间过滤，避免短时插针误触。
用终端全局变量而非局部缓存，在初始化函数里读是否存在、不存在再写默认值，重启 EA 数值保留。
