图表属性枚举里的可见区域与配色钩子
在 MT5 的图表对象模型里，CHART_PROP_* 系列枚举直接暴露了图表的几何与视觉状态。做价格行为分析时，最先要盯的是可见范围类属性：CHART_PROP_VISIBLE_BARS 给出图表当前可显示的 K 线总数，CHART_PROP_FIRST_VISIBLE_BAR 标记最左侧那根可见 Bar 的编号，两者相减能反推出视窗右边界位置。 CHART_PROP_WIDTH_IN_BARS 与 CHART_PROP_WIDTH_IN_PIXELS 是一对互补量——前者以 Bar 计宽，后者以像素计宽。若你的屏幕横向分辨率为 1920 像素，而该属性返回 960，则单根 Bar 平均占用约 2 像素，这种极端压缩下裸 K 形态会严重失真，倾向误判影线。 配色类属性则是自动化标注的前提。CHART_PROP_COLOR_CHART_UP / DOWN 控制涨跌 Bar 的边框，CHART_PROP_COLOR_CANDLE_BULL / BEAR 控制实体填充；用 ChartGetInteger 读出来后，你可以在 EA 里比对当前主题是否暗色，从而切换 overlay 线条的对比色。外汇与贵金属杠杆高，视觉错位可能放大错单概率，读取后务必在 MT5 视觉回放里人工复核一次。 CHART_PROP_SHOW_TRADE_LEVELS 决定是否绘制持仓与挂单水平线。写脚本批量截图时若忘了同步这个属性，可能出现「实盘有 SL 线、回测图无 SL 线」的偏差，让形态统计失效。

「图表整数属性的尾段与排序基址」
上面这段枚举收尾列出了图表窗口的交互与布局类整数属性，从鼠标拖拽交易水平线（CHART_PROP_DRAG_TRADE_LEVELS）到非停靠窗口相对虚拟屏幕的四至坐标，都属于可被 ChartGetInteger/ChartSetInteger 读写的运行时状态。其中 CHART_PROP_WINDOW_NUM 标黄项指明指标所在图表子窗口序号，多窗体 EA 定位绘图层时必用。 宏定义给出两个硬数字：整数属性总量 CHART_PROP_INTEGER_TOTAL 为 67，排序跳过量 CHART_PROP_INTEGER_SKIP 为 0，说明全部整数属性都参与后续排序逻辑，没有为 DOM 预留废弃位。 排序基址由 FIRST_CHART_DBL_PROP 与 FIRST_CHART_STR_PROP 算出，前者等于 67-0，即双精度属性从枚举值 67 起跳；字符串属性再叠加双精度总量偏移。ENUM_SORT_CHART_MODE 里 SORT_BY_CHART_ID=0 与 SORT_BY_CHART_TIMEFRAME 表明，图表集合既能按 ID 也能按周期归类，写多图表管理器时可直接套用这两个枚举值。 开 MT5 在 MetaEditor 搜 CHART_PROP_WINDOW_NUM，改一下附属窗口指标测试其返回值，能验证上面偏移计算是否与你当前终端版本一致。外汇与贵金属杠杆品种波动剧烈，脚本仅作界面状态管理，不涉及方向判断，实操请自担高风险。

◍ 图表对象枚举里的排序锚点
在 MQL5 里用 ChartGetInteger 或 ChartSetInteger 遍历多图表时，这组 SORT_BY_CHART_* 枚举决定了你按哪个属性把图表对象排进列表。它们不是指标参数，而是图表自身状态开关的索引标签。 比如 SORT_BY_CHART_SHOW 对应价格图是否绘制的属性，SORT_BY_CHART_IS_OBJECT 区分该条目是不是 OBJ_CHART 类型的图表对象，SORT_BY_CHART_BRING_TO_TOP 则看图表是否被设为置顶显示。 交互类开关也在这里：SORT_BY_CHART_CONTEXT_MENU 管右键菜单权限，SORT_BY_CHART_CROSSHAIR_TOO 管中键十字光标，SORT_BY_CHART_MOUSE_SCROLL 管左键横向滚动。事件转发类如 SORT_BY_CHART_EVENT_MOUSE_WHEEL、SORT_BY_CHART_EVENT_OBJECT_DELETE，决定鼠标滚轮或图形对象销毁事件是否广播给图表上所有 MQL5 程序。 开 MT5 按 F4 进 MetaEditor，搜 ENUM_CHART_PROPERTY_INTEGER 就能看到完整清单；写多图表管理器时，挑 SORT_BY_CHART_MODE 和 SORT_BY_CHART_SCALE 做排序键，可能比按窗口序号更稳。外汇与贵金属图表多开时杠杆风险高，先用模拟盘验证枚举读取逻辑。

图表属性枚举的排序维度清单
在 MT5 的图表对象枚举体系里，有一组以 SORT_BY_CHART_ 开头的常量，专门用来按图表可视属性做排序或检索。它们覆盖了从 OHLC 文字显示、买卖价水平线，到周期分隔符、网格、成交量模式等界面元素。 下面这段枚举定义给出了可直接抄进 EA 或脚本的常量名与含义，注意每个都对应 ChartGetInteger/ChartSetInteger 的一类属性标识： SORT_BY_CHART_SHOW_OHLC 控制左上角 OHLC 数值的显示开关；SORT_BY_CHART_SHOW_BID_LINE 对应图表上 Bid 水平线；SORT_BY_CHART_SHOW_ASK_LINE 对应 Ask 水平线；SORT_BY_CHART_SHOW_LAST_LINE 则是 Last 成交价水平线。 继续往下看，SORT_BY_CHART_SHOW_PERIOD_SEP 管周期竖线分隔，SORT_BY_CHART_SHOW_GRID 管网格，SORT_BY_CHART_SHOW_VOLUMES 管成交量显示模式，SORT_BY_CHART_SHOW_OBJECT_DESCR 管对象文字描述是否显示。 窗口类属性也在这组里：SORT_BY_CHART_VISIBLE_BARS 是可显示 bar 数，SORT_BY_CHART_WINDOWS_TOTAL 含指标子窗口的总数，SORT_BY_CHART_WINDOW_HANDLE 是图表句柄，SORT_BY_CHART_WINDOW_YDISTANCE 是子窗口与上边框的 Y 像素距离。 还有第一可见 bar 序号、以 bar 或像素计的宽高：SORT_BY_CHART_FIRST_VISIBLE_BAR、SORT_BY_CHART_WIDTH_IN_BARS、SORT_BY_CHART_WIDTH_IN_PIXELS、SORT_BY_CHART_HEIGHT_IN_PIXELS。颜色类则包括背景、前景轴色、网格、成交量、阳线阴线实体与影线色，共 7 个 COLOR_ 后缀常量。 开 MT5 新建脚本，把这些常量打印出来对照 ChartGetInteger 返回值，就能确认当前图表状态。外汇与贵金属波动剧烈，用脚本批量读图表属性时务必先开模拟盘验证。

「图表对象枚举里的排序锚点」
在 MQL5 的图表批量管理逻辑里，SORT_BY_CHART_* 系列枚举决定了你用 ChartGetInteger/ChartSetInteger 遍历或排序图表时，到底按哪个属性做键。上面这段列出了从颜色类到窗口布局类的全部可用锚点，其中 SORT_BY_CHART_WINDOW_NUM 是定位子窗口指标最常用的索引依据。 颜色类里 SORT_BY_CHART_COLOR_CANDLE_BULL 与 SORT_BY_CHART_COLOR_CANDLE_BEAR 分别对应阳线实体与阴线实体的配色，做多周期视觉一致性脚本时可直接读这两个值；SORT_BY_CHART_COLOR_STOP_LEVEL 则锁定止损止盈线的颜色，方便在 EA 里统一风控线样式。 窗口状态类值得注意：SORT_BY_CHART_IS_DOCKED 配合 SORT_BY_CHART_FLOAT_LEFT / TOP / RIGHT / BOTTOM 四个浮窗坐标枚举，能在多屏交易环境下精确还原未停靠图表的位置。开 MT5 按 F4 把这些枚举粘进一段 ChartGetInteger 循环，就能列出当前终端所有图表的停靠与坐标状态。

◍ 枚举图表排序维度与指标窗口类骨架
在 MT5 的图表集合管理逻辑里，排序枚举把双精度属性和字符串属性分开锚定：双精度部分从 FIRST_CHART_DBL_PROP 起算，涵盖零柱右边界偏移百分比、左边界固定位置百分比、固定最大最小值、每柱点数比例以及图表实际价格上下沿；字符串部分从 FIRST_CHART_STR_PROP 起算，覆盖图表注释、EA 名、脚本名、主窗口指标名与品种名。 这些枚举值直接决定你用 ChartGetSortedBy() 一类接口批量巡检多图表时的比对键。比如按 SORT_BY_CHART_SYMBOL 排，能快速把同品种图表聚拢；按 SORT_BY_CHART_EXPERT_NAME 排，则便于定位挂了特定 EA 的图表。 紧随其后的 CWndInd 类只搭了最小骨架：私有成员存图表 ID、指标短名、列表序号、子窗口序号与指标句柄，公有方法先给了一个 GetObject() 返回自身指针。这个类后续若扩展，大概率要接 ChartIndicatorGet() 拿句柄、WindowIndicatorName() 验子窗口，外汇与贵金属图表多周期叠加时高风险，句柄失效要先判 ERR_INVALID_HANDLE。 开 MT5 新建 EA 把下面枚举和类头抄进项目，编译过一遍就能确认这些成员偏移量是否和你用的终端版本一致。
