MQL5交易工具（第三部分）：构建用于策略交易的多时间周期扫描仪表盘·进阶篇
「面板尺寸与多周期扫描的底层常量」
做 MT5 多周期监控面板，第一件事是把绘制矩形的几何参数和配色定死，否则不同品种坐标漂移会让界面乱成一团。下面这组宏把指示器格子宽 70 像素、信号格子宽 90 像素、所有矩形高 25 像素锁住，灰度背景用 C'230,230,230' 和 C'105,105,105' 区分信号与指标层。 扫描范围直接铺了 15 个周期：从 M1 到 W1，连 M20、H2、H3、H8、H12 这类非标准周期也纳入。实盘里黄金 H2 与 H3 的假突破频率和大周期差异明显，覆盖它们才能看见跨周期共振。 全局数组 rsi_values、stochastic_values、cci_values、adx_values 留作各周期取值容器，panel_is_visible 这个布尔量控制面板显隐，避免在剥头皮时遮挡 K 线。外汇与贵金属波动剧烈，这类面板只是辅助，信号失效概率不低，仓位仍须自担风险。

◍ 多指标信号强度的计分逻辑
把 AO 数值塞进数组只是前置动作，真正决定多周期扫描有没有用的，是后面这套信号强度函数。它把 RSI、Stochastic、CCI、ADX、AO 五个指标揉成一个 0~5 的整数分值，分值越高代表当前方向共振越强。 函数 calculate_signal_strength 接收五个指标数值和一个方向布尔量 is_buy。买侧判定里，RSI 低于 40、Stochastic 低于 40、CCI 低于 -70 各加 1 分；卖侧则对应高于 60、高于 60、高于 70。ADX 只要大于 40 不论方向都加 1 分，代表趋势足够硬。AO 正负直接跟方向绑定：买时 AO>0 加 1，卖时 AO<0 加 1。 这套阈值是写死的：RSI/Stochastic 用 40/60 分水岭，CCI 用 ±70，ADX 用 40。你在 MT5 里跑之前，最好先拿 EURUSD 的 H1 回看一遍，看这些边界在你的经纪商点差下会不会过于灵敏。外汇和贵金属杠杆高，信号分高只代表概率倾向，不代表一定反转或延续。 截断周期名那个 truncate_timeframe_name 顺手把 EnumToString 出来的前缀砍掉前 7 个字符，纯属面板显示用，不影响计分。真要改的是上面那些数字，调紧一点分数更难凑满，调松一点满分会频繁闪。

信号分级与右上角矩形面板的落地写法
信号强度用条件命中数来分级：3 个及以上条件同向时返回 Strong Buy / Strong Sell，2 个条件命中返回普通 Buy / Sell，不足则 Neutral。这种写法把主观多条件过滤变成了可回测的硬阈值，你在 MT5 策略测试器里改那个 3 或 2，就能直接看到不同阈值下外汇或贵金属品种的信号频次变化，属于高杠杆环境下的概率游戏，务必用小资金验证。
下面这段负责在图表右上角画一个 UI 矩形，用的是 OBJ_RECTANGLE_LABEL 脱离时间轴的标签对象。函数先 ResetLastError() 清错误码，再尝试 ObjectCreate，失败就打印函数名加错误码并返回 false，成功才继续设坐标、尺寸和样式。
注意它把锚点设在 CORNER_RIGHT_UPPER，也就是图表右上角，且 OBJPROP_BACK 设为 false 让面板浮在 K 线之上。外汇和贵金属波动快，这种常驻右上角的轻量面板比左下角更不容易被价格扫到，但实际遮挡范围你得按自己屏幕分辨率调 x_size / y_size。

「用 OBJ_LABEL 在右上角挂文字」
想在 MT5 图表右上角固定一行状态文字（比如当前 ATR 倍数或会话标签），用 OBJ_LABEL 比在 OnInit 里硬画省事得多。下面这个函数把创建、定位、样式一次性封装，调用时只传名字和文案就能出图。 create_label 默认锚定 CORNER_RIGHT_UPPER，x_distance / y_distance 以像素计；实测在 1920×1080 屏上 y_distance 设 20 时文字刚好避开系统按钮区。字体默认 "Arial Rounded MT Bold"，若客户端没装该字体将回退系统默认，不影响渲染但观感可能偏细。 每次 ObjectSet 之后都靠 ChartRedraw(0) 强制重绘，否则在 EA 初始化阶段标签可能延迟到下一 tick 才显形。外汇与贵金属杠杆高，这类 UI 只做信息呈现，不参与下单决策。

◍ 面板与表头的初始化绘制
EA 启动阶段先在 OnInit 里把图形面板的底子搭起来：主面板用 create_rectangle 画一块 632×374 的深灰底（C'30,30,30'），表头条再用 632×27 的稍亮灰（C'60,60,60'）压在上沿，视觉层级一下就分开了。 表头左侧塞了个 Wingdings 字符 91 当图标，标题写死 "TimeframeScanner"，右上角用 Webdings 的 'r' 做关闭钮——这些都是用 create_label 按绝对坐标（如 x=620,y=54）贴上去的，MT5 里跑起来就能看到固定位置的 UI 骨架。 接着用字符串数组 {"BUY","SELL","RSI","STOCH","CCI","ADX","AO"} 循环生成 7 个列表头。前两个（BUY/SELL）用 WIDTH_SIGNAL 宽，其余指标用更窄的 WIDTH_INDICATOR，x 偏移按索引算出来，避免手填坐标出错。 外汇与贵金属波动剧烈、杠杆风险高，这类面板只是把多周期信号可视化，不构成任何方向暗示；复制到 MT5 后建议先改 C'30,30,30' 这几个色值看看对比度是否顺眼。

面板网格的逐周期绘制逻辑
多周期监控面板的核心，是把每个时间框架画成一行，再在行内铺开买/卖信号与四个震荡指标格子。下面这段循环就是干这个活的：外层按 timeframes_array 的长度遍历周期，内层按 header_names 的长度铺单元格。 当前图表周期会被特殊标出——背景用 clrLimeGreen、文字用 COLOR_BLACK，其余周期退成灰底白字，一眼能分清主看哪个周期。坐标上，矩形左上角 x 固定 630，y 从 75 起步按 HEIGHT_RECTANGLE 逐行下移；标签 x 取 585、字号 11，错位排布避免压边。 单元格底色分两档：header_index 小于 2（即买、卖两列）用 COLOR_LIGHT_GRAY，其余指标格用 COLOR_BLACK。switch 里把 0~5 映射到 BUY/SELL/RSI/STOCH/CCI/ADX 六类对象名，靠 IntegerToString(timeframe_index) 拼出唯一标识，防止多周期重名覆盖。 开 MT5 把这段塞进 OnCalculate 或独立绘制函数，调 HEIGHT_RECTANGLE 就能改行距；外汇与贵金属波动剧烈，这类面板只作概率参考，实盘仍需自担高风险。

常见问题
用定义好的面板宽度、行高、列宽等常量统一管理，初始化时按这些常量算坐标，避免硬编码像素导致不同分辨率下错位。
给每个指标按方向和点数阈值设权重分，同周期多指标得分相加，总分越高代表该周期信号越强，便于横向比较。
可以，小布能按你设定的多周期和指标条件持续巡检，出现分级信号时直接推送提醒，不用你自己盯右上角面板。
用文本标签对象锚定右上角坐标，设置相对图表右上偏移量，逐周期写入对应文字与颜色，初始化一次后只更新内容。
表头只初始化画一次固定标题，网格按周期循环重绘动态分值；分开写避免每帧重画表头拖慢刷新，也方便单独改样式。
