概述
在系列文章的第一部分中，我们使用MetaQuotes Language 5（MQL5）为MetaTrader 5平台开发了一款交易助手工具，旨在简化待处理订单的挂单操作。如今，我们通过引入动态视觉反馈机制进一步升级该工具的交互性。新增功能包括可拖拽控制面板、悬停导航特效，以及实时订单验证系统，确保交易参数精准匹配市场行情。本文将通过以下子主题展开论述：
这些章节将助力我们打造响应更迅速、操作更直观、用户体验更友好的交易工具。
提升交互性的概念优化方案
我们致力于通过增强直观性与适应性来升级交易助手工具。首先引入可自由定位在交易图表上的拖拽式控制面板。这种灵活性使我们能够根据工作流程定制界面，无论是同时管理多个图表，还是专注于单一交易策略。此外，我们将集成悬停效果：当鼠标划过按钮或图表元素时，系统会即时高亮显示，通过视觉反馈简化导航流程并降低操作失误率。
实时订单验证是另一项核心改进，它会在执行前确保入场价、止损价和止盈价与当前市场价格保持逻辑一致性。该功能通过防止无效交易配置增强操作信心，在保持系统简洁性的同时提升参数精度。这些优化将共同构建一个响应迅速、以用户为中心的决策支持工具，为后续风险管理等高级功能奠定基础。简言之，下图展示了我们的目标成果：
在MQL5中的实现
为实现MQL5中的开发目标，我们需首先定义以下附加面板对象、拖拽及交互确认变量，用于追踪用户与面板或价格工具的交互行为。
// Control panel object names #define PANEL_BG "PANEL_BG" //--- Define constant for panel background object name #define PANEL_HEADER "PANEL_HEADER" //--- Define constant for panel header object name #define LOT_EDIT "LOT_EDIT" //--- Define constant for lot size edit field object name #define PRICE_LABEL "PRICE_LABEL" //--- Define constant for price label object name #define SL_LABEL "SL_LABEL" //--- Define constant for stop-loss label object name #define TP_LABEL "TP_LABEL" //--- Define constant for take-profit label object name #define BUY_STOP_BTN "BUY_STOP_BTN" //--- Define constant for buy stop button object name #define SELL_STOP_BTN "SELL_STOP_BTN" //--- Define constant for sell stop button object name #define BUY_LIMIT_BTN "BUY_LIMIT_BTN" //--- Define constant for buy limit button object name #define SELL_LIMIT_BTN "SELL_LIMIT_BTN" //--- Define constant for sell limit button object name #define PLACE_ORDER_BTN "PLACE_ORDER_BTN" //--- Define constant for place order button object name #define CANCEL_BTN "CANCEL_BTN" //--- Define constant for cancel button object name #define CLOSE_BTN "CLOSE_BTN" //--- Define constant for close button object name // Variables for dragging panel bool panel_dragging = false; //--- Flag to track if panel is being dragged int panel_drag_x = 0, panel_drag_y = 0; //--- Mouse coordinates when drag starts int panel_start_x = 0, panel_start_y = 0; //--- Panel coordinates when drag starts // Button and rectangle hover states bool buy_stop_hovered = false; //--- Buy Stop button hover state bool sell_stop_hovered = false; //--- Sell Stop button hover state bool buy_limit_hovered = false; //--- Buy Limit button hover state bool sell_limit_hovered = false; //--- Sell Limit button hover state bool place_order_hovered = false; //--- Place Order button hover state bool cancel_hovered = false; //--- Cancel button hover state bool close_hovered = false; //--- Close button hover state bool header_hovered = false; //--- Header hover state bool rec1_hovered = false; //--- REC1 (TP) hover state bool rec3_hovered = false; //--- REC3 (Entry) hover state bool rec5_hovered = false; //--- REC5 (SL) hover state
我们通过定义实现面板拖拽与悬停效果的核心变量，着手开始实现交易工具的交互性优化功能（基于MetaTrader 5界面）。首先使用#define指令创建常量"PANEL_HEADER"，用于标识控制面板的标题栏区域，该区域将作为可拖拽操作区。为支持拖拽功能，我们声明以下变量：布尔型标识"panel_dragging"用于追踪面板是否正在被移动；整型变量"panel_drag_x"和"panel_drag_y"记录鼠标开始拖拽时的坐标位置；整型变量"panel_start_x"和"panel_start_y"存储面板初始位置，用于计算拖拽过程中的新坐标。
我们同时引入布尔变量管理各按钮与图表矩形的悬停状态，包括用于各按钮和面板标题的"buy_stop_hovered"、"sell_stop_hovered"、"buy_limit_hovered"、"sell_limit_hovered"、"place_order_hovered"、"cancel_hovered"、"close_hovered"和 "header_hovered"，以及用于对于止盈、入场和止损矩形状态的 "rec1_hovered"、"rec3_hovered"和"rec5_hovered"。 这些变量将实时检测鼠标悬停状态，触发颜色变化等视觉反馈，从而优化工具界面的导航与交互体验。接下来，我们需要获取价格工具数值并进行交易验证。
//+------------------------------------------------------------------+ //| Check if order setup is valid | //+------------------------------------------------------------------+ bool isOrderValid() { if(!tool_visible) return true; //--- No validation needed if tool is not visible double current_price = SymbolInfoDouble(Symbol(), SYMBOL_BID); //--- Get current bid price double entry_price = Get_Price_d(PR_HL); //--- Get entry price double sl_price = Get_Price_d(SL_HL); //--- Get stop-loss price double tp_price = Get_Price_d(TP_HL); //--- Get take-profit price if(selected_order_type == "BUY_STOP") { //--- Buy Stop: Entry must be above current price, TP above entry, SL below entry if(entry_price <= current_price || tp_price <= entry_price || sl_price >= entry_price) { return false; } } else if(selected_order_type == "SELL_STOP") { //--- Sell Stop: Entry must be below current price, TP below entry, SL above entry if(entry_price >= current_price || tp_price >= entry_price || sl_price <= entry_price) { return false; } } else if(selected_order_type == "BUY_LIMIT") { //--- Buy Limit: Entry must be below current price, TP above entry, SL below entry if(entry_price >= current_price || tp_price <= entry_price || sl_price >= entry_price) { return false; } } else if(selected_order_type == "SELL_LIMIT") { //--- Sell Limit: Entry must be above current price, TP below entry, SL above entry if(entry_price <= current_price || tp_price >= entry_price || sl_price <= entry_price) { return false; } } return true; //--- Order setup is valid }
在此阶段，我们通过"isOrderValid"函数实现订单实时验证功能，确保交易配置与市场条件动态匹配。首先检查"tool_visible"状态，如果为false则直接返回true跳过验证（工具未激活时无需校验）。通过SYMBOL_BID的SymbolInfoDouble函数获取当前市场价格，并调用"Get_Price_d"函数分别获取入场价("entry_price")、止损价("sl_price")和止盈价("tp_price")，对应参数类型为"PR_HL"、"SL_HL"和"TP_HL"。
对于买入止损单（"BUY_STOP"），检验"entry_price"是否高于"current_price"，"tp_price"是否高于"entry_price"，"sl_price"是否低于"entry_price"；对于卖出止损单（"SELL_STOP"），检验"entry_price"是否低于"current_price"，"tp_price"是否低于"entry_price"，"sl_price"是否高于"entry_price"；对于买入限价单（"BUY_LIMIT"），检验"entry_price"是否低于"current_price"，"tp_price"是否高于"entry_price"，"sl_price"是否低于"entry_price"；对于卖出限价单（"SELL_LIMIT"），检验"entry_price"是否高于"current_price"，"tp_price"是否低于"entry_price"，"sl_price"是否高于"entry_price"。如果任一条件不满足则返回false（无效配置），全部通过则返回true（有效配置）。之后我们根据订单有效性更新矩形的显示颜色。
//+------------------------------------------------------------------+ //| Update rectangle colors based on order validity and hover | //+------------------------------------------------------------------+ void updateRectangleColors() { if(!tool_visible) return; //--- Skip if tool is not visible bool is_valid = isOrderValid(); //--- Check order validity if(!is_valid) { //--- Gray out REC1 and REC5 if order is invalid, with hover effect ObjectSetInteger(0, REC1, OBJPROP_BGCOLOR, rec1_hovered ? C'100,100,100' : clrGray); ObjectSetInteger(0, REC5, OBJPROP_BGCOLOR, rec5_hovered ? C'100,100,100' : clrGray); } else { //--- Restore original colors based on order type and hover state if(selected_order_type == "BUY_STOP" || selected_order_type == "BUY_LIMIT") { ObjectSetInteger(0, REC1, OBJPROP_BGCOLOR, rec1_hovered ? C'0,100,0' : clrGreen); //--- TP rectangle (dark green on hover) ObjectSetInteger(0, REC5, OBJPROP_BGCOLOR, rec5_hovered ? C'139,0,0' : clrRed); //--- SL rectangle (dark red on hover) } else { ObjectSetInteger(0, REC1, OBJPROP_BGCOLOR, rec1_hovered ? C'0,100,0' : clrGreen); //--- TP rectangle (dark green on hover) ObjectSetInteger(0, REC5, OBJPROP_BGCOLOR, rec5_hovered ? C'139,0,0' : clrRed); //--- SL rectangle (dark red on hover) } } ObjectSetInteger(0, REC3, OBJPROP_BGCOLOR, rec3_hovered ? C'105,105,105' : clrLightGray); //--- Entry rectangle (darker gray on hover) ChartRedraw(0); //--- Redraw chart }
我们通过实现 "updateRectangleColors"函数，根据订单有效性和悬停状态动态更新图表矩形颜色，强化工具的视觉反馈机制。当"tool_visible"为false时，我们跳过处理，首先调用"isOrderValid"函数验证订单有效性，随后使用ObjectSetInteger函数设置矩形颜色：如果订单无效，则"REC1"（止盈）和"REC5"（止损）设置为灰色（"clrGray"或悬停时为C'100,100,100'）；如果订单有效，则买入止损/买入限价/卖出订单设置为绿色/红色（"clrGreen"/"clrRed"或悬停时为C'0,100,0'/C'139,0,0'），"REC3" (入场点) 始终设置为浅灰色（"clrLightGray"或悬停时为C'105,105,105'），最后调用ChartRedraw刷新图表显示。
此后，我们需要按照如下方式获取按钮的悬停状态：
//+------------------------------------------------------------------+ //| Update button and header hover state | //+------------------------------------------------------------------+ void updateButtonHoverState(int mouse_x, int mouse_y) { // Define button names and their properties string buttons[] = {BUY_STOP_BTN, SELL_STOP_BTN, BUY_LIMIT_BTN, SELL_LIMIT_BTN, PLACE_ORDER_BTN, CANCEL_BTN, CLOSE_BTN}; bool hover_states[] = {buy_stop_hovered, sell_stop_hovered, buy_limit_hovered, sell_limit_hovered, place_order_hovered, cancel_hovered, close_hovered}; color normal_colors[] = {clrForestGreen, clrFireBrick, clrForestGreen, clrFireBrick, clrDodgerBlue, clrSlateGray, clrCrimson}; color hover_color = clrDodgerBlue; //--- Bluish color for hover color hover_border = clrBlue; //--- Bluish border for hover for(int i = 0; i < ArraySize(buttons); i++) { int x = (int)ObjectGetInteger(0, buttons[i], OBJPROP_XDISTANCE); int y = (int)ObjectGetInteger(0, buttons[i], OBJPROP_YDISTANCE); int width = (int)ObjectGetInteger(0, buttons[i], OBJPROP_XSIZE); int height = (int)ObjectGetInteger(0, buttons[i], OBJPROP_YSIZE); bool is_hovered = (mouse_x >= x && mouse_x <= x + width && mouse_y >= y && mouse_y <= y + height); if(is_hovered && !hover_states[i]) { // Mouse entered button ObjectSetInteger(0, buttons[i], OBJPROP_BGCOLOR, hover_color); ObjectSetInteger(0, buttons[i], OBJPROP_BORDER_COLOR, hover_border); hover_states[i] = true; } else if(!is_hovered && hover_states[i]) { // Mouse left button ObjectSetInteger(0, buttons[i], OBJPROP_BGCOLOR, normal_colors[i]); ObjectSetInteger(0, buttons[i], OBJPROP_BORDER_COLOR, clrBlack); hover_states[i] = false; } } // Update header hover state int header_x = (int)ObjectGetInteger(0, PANEL_HEADER, OBJPROP_XDISTANCE); int header_y = (int)ObjectGetInteger(0, PANEL_HEADER, OBJPROP_YDISTANCE); int header_width = (int)ObjectGetInteger(0, PANEL_HEADER, OBJPROP_XSIZE); int header_height = (int)ObjectGetInteger(0, PANEL_HEADER, OBJPROP_YSIZE); bool is_header_hovered = (mouse_x >= header_x && mouse_x <= header_x + header_width && mouse_y >= header_y && mouse_y <= header_y + header_height); if(is_header_hovered && !header_hovered) { ObjectSetInteger(0, PANEL_HEADER, OBJPROP_BGCOLOR, C'030,030,030'); //--- Darken header header_hovered = true; } else if(!is_header_hovered && header_hovered) { ObjectSetInteger(0, PANEL_HEADER, OBJPROP_BGCOLOR, C'050,050,050'); //--- Restore header color header_hovered = false; } // Update tool rectangle hover states if(tool_visible) { int x1 = (int)ObjectGetInteger(0, REC1, OBJPROP_XDISTANCE); int y1 = (int)ObjectGetInteger(0, REC1, OBJPROP_YDISTANCE); int width1 = (int)ObjectGetInteger(0, REC1, OBJPROP_XSIZE); int height1 = (int)ObjectGetInteger(0, REC1, OBJPROP_YSIZE); int x3 = (int)ObjectGetInteger(0, REC3, OBJPROP_XDISTANCE); int y3 = (int)ObjectGetInteger(0, REC3, OBJPROP_YDISTANCE); int width3 = (int)ObjectGetInteger(0, REC3, OBJPROP_XSIZE); int height3 = (int)ObjectGetInteger(0, REC3, OBJPROP_YSIZE); int x5 = (int)ObjectGetInteger(0, REC5, OBJPROP_XDISTANCE); int y5 = (int)ObjectGetInteger(0, REC5, OBJPROP_YDISTANCE); int width5 = (int)ObjectGetInteger(0, REC5, OBJPROP_XSIZE); int height5 = (int)ObjectGetInteger(0, REC5, OBJPROP_YSIZE); bool is_rec1_hovered = (mouse_x >= x1 && mouse_x <= x1 + width1 && mouse_y >= y1 && mouse_y <= y1 + height1); bool is_rec3_hovered = (mouse_x >= x3 && mouse_x <= x3 + width3 && mouse_y >= y3 && mouse_y <= y3 + height3); bool is_rec5_hovered = (mouse_x >= x5 && mouse_x <= x5 + width5 && mouse_y >= y5 && mouse_y <= y5 + height5); if(is_rec1_hovered != rec1_hovered || is_rec3_hovered != rec3_hovered || is_rec5_hovered != rec5_hovered) { rec1_hovered = is_rec1_hovered; rec3_hovered = is_rec3_hovered; rec5_hovered = is_rec5_hovered; updateRectangleColors(); //--- Update colors based on hover state } } // Update hover state variables buy_stop_hovered = hover_states[0]; sell_stop_hovered = hover_states[1]; buy_limit_hovered = hover_states[2]; sell_limit_hovered = hover_states[3]; place_order_hovered = hover_states[4]; cancel_hovered = hover_states[5]; close_hovered = hover_states[6]; ChartRedraw(0); //--- Redraw chart }
我们通过实现"updateButtonHoverState"函数管理按钮与图表元素的悬停效果，显著提升工具的交互性。我们定义以下数组：按钮名称"buttons"（从"BUY_STOP_BTN"到"CLOSE_BTN"）、悬停状态"hover_states"（对应各个按钮的悬停标识，从"buy_stop_hovered"到"close_hovered"）、默认颜色 "normal_colors"（存储各按钮的初始颜色值），以及表示悬停状态的悬停背景色"normal_colors"（clrDodgerBlue）和悬停边框色"hover_border"（"clrBlue"）。
针对各个按钮，我们使用ObjectGetInteger函数获取按钮的位置坐标和尺寸，检查鼠标坐标"mouse_x"和"mouse_y"是否落在按钮区域内，并且使用ObjectSetInteger更新"OBJPROP_BGCOLOR"和"OBJPROP_BORDER_COLOR"为"hover_color"或"normal_colors"，并同步更新"hover_states"标识。
对于"PANEL_HEADER"，我们同样检查其悬停状态，通过ObjectSetInteger设置悬停时背景加深为 "C'030,030,030'"，而离开时恢复为 "C'050,050,050'"。当"tool_visible"为true时，我们检查"REC1"、"REC3"、"REC5"的边界，更新对应的"rec1_hovered"、"rec3_hovered"、"rec5_hovered"标识，如果状态发生变化，则调用"updateRectangleColors"刷新矩形颜色。我们将"buy_stop_hovered"到"close_hovered"的所有悬停标识与"hover_states"同步，并调用ChartRedraw重绘图表。随后，我们在OnChartEvent事件处理器中调用这些函数，即可实现实时更新。

鉴于我们已定义OnChartEvent函数，现聚焦于新增交互功能的增强逻辑实现，包括面板拖拽、悬停状态更新及订单有效性验证。针对CHARTEVENT_OBJECT_CLICK，调用"updateRectangleColors"函数，根据订单有效性更新关联矩形的可视化效果，从而扩展"BUY_STOP_BTN"、"SELL_STOP_BTN"、"BUY_LIMIT_BTN"和"SELL_LIMIT_BTN"的按钮点击处理，对于"PLACE_ORDER_BTN"，我们额外增加"isOrderValid"函数进行校验，如果订单无效，则通过Print记录错误信息，并防止交易出错，如下图所示：
我们还会在点击操作后引入“updateButtonHoverState”函数，以刷新悬停效果，并使用“lparam”和“dparam”来获取鼠标坐标。对于CHARTEVENT_MOUSE_MOVE，我们通过检查鼠标点击是否位于“PANEL_HEADER”（通过ObjectGetInteger函数获取）范围内来添加面板拖动功能。如果满足在此范围内，则将“panel_dragging”设置为true，将坐标存储在“panel_drag_x”、“panel_drag_y”、“panel_start_x”和“panel_start_y”中，并使用ChartSetInteger函数禁用图表滚动。
在拖动过程中（“panel_dragging”为true且"MouseState"为1时），我们计算位移量（“dx”、“dy”），更新“panel_x”和“panel_y”的坐标值，并使用 ObjectSetInteger重新定位所有的面板对象（如“PANEL_BG”、“PANEL_HEADER”、“CLOSE_BTN”、“LOT_EDIT”等），随后调用ChartRedraw更新图表显示。当鼠标释放时，我们重置“panel_dragging”，并重新启用图表滚动功能。为确保矩形（如“REC1”、“REC3”、“REC5”）的拖动操作不与面板拖动产生冲突，我们通过检查“!panel_dragging”条件来避免这种情况，并在“movingState_R1”、“movingState_R5”和“movingState_R3”状态下调用“updateRectangleColors”更新矩形颜色，以反映其悬停和有效性状态。
我们已高亮显示了一些关键代码段，以供您参考。可视化展示如下：
此外，由于我们已经使用了标题面板对象，其创建方法如下：
//+------------------------------------------------------------------+ //| Create control panel | //+------------------------------------------------------------------+ void createControlPanel() { // Background rectangle ObjectCreate(0, PANEL_BG, OBJ_RECTANGLE_LABEL, 0, 0, 0); //--- Create panel background rectangle ObjectSetInteger(0, PANEL_BG, OBJPROP_XDISTANCE, panel_x); //--- Set background x-position ObjectSetInteger(0, PANEL_BG, OBJPROP_YDISTANCE, panel_y); //--- Set background y-position ObjectSetInteger(0, PANEL_BG, OBJPROP_XSIZE, 250); //--- Set background width ObjectSetInteger(0, PANEL_BG, OBJPROP_YSIZE, 280); //--- Set background height ObjectSetInteger(0, PANEL_BG, OBJPROP_BGCOLOR, C'070,070,070'); //--- Set background color ObjectSetInteger(0, PANEL_BG, OBJPROP_BORDER_COLOR, clrWhite); //--- Set border color ObjectSetInteger(0, PANEL_BG, OBJPROP_BACK, false); //--- Set background to foreground // Header rectangle (inside panel) createButton(PANEL_HEADER,"",panel_x+2,panel_y+2,250-4,28-3,clrBlue,C'050,050,050',12,C'050,050,050',false); createButton(CLOSE_BTN, CharToString(203), panel_x + 209, panel_y + 1, 40, 25, clrWhite, clrCrimson, 12, clrBlack, false, "Wingdings"); //--- Create close button //--- }
在“createControlPanel”函数中，我们使用“createButton”函数在工具的控制面板上添加一个名为“PANEL_HEADER”的按钮，该按钮的位置为“panel_x+2”、“panel_y+2”，尺寸为246x25，样式设置为蓝色文本（clrBlue）、深灰色背景/边框（“C'050,050,050'”），且不显示标签，以便在OnChartEvent事件中实现面板拖动功能。另外，我们需要执行的操作是参照如下方式销毁该面板：
//+------------------------------------------------------------------+ //| Delete control panel objects | //+------------------------------------------------------------------+ void deletePanel() { ObjectDelete(0, PANEL_BG); //--- Delete panel background ObjectDelete(0, PANEL_HEADER); //--- Delete panel header ObjectDelete(0, LOT_EDIT); //--- Delete lot edit field ObjectDelete(0, PRICE_LABEL); //--- Delete price label ObjectDelete(0, SL_LABEL); //--- Delete SL label ObjectDelete(0, TP_LABEL); //--- Delete TP label ObjectDelete(0, BUY_STOP_BTN); //--- Delete Buy Stop button ObjectDelete(0, SELL_STOP_BTN); //--- Delete Sell Stop button ObjectDelete(0, BUY_LIMIT_BTN); //--- Delete Buy Limit button ObjectDelete(0, SELL_LIMIT_BTN); //--- Delete Sell Limit button ObjectDelete(0, PLACE_ORDER_BTN); //--- Delete Place Order button ObjectDelete(0, CANCEL_BTN); //--- Delete Cancel button ObjectDelete(0, CLOSE_BTN); //--- Delete Close button ChartRedraw(0); //--- Redraw chart }
在此阶段，我们对“deletePanel”函数进行更新，以确保工具的控制面板能够通过移除所有关联对象（包括我们最近新增的标题栏）得到妥善地清理。我们使用ObjectDelete函数从MetaTrader 5图表中移除以下对象：面板背景（“PANEL_BG”）、新添加的标题栏（“PANEL_HEADER”）、手数输入框（“LOT_EDIT”）、标签（“PRICE_LABEL”、“SL_LABEL”、“TP_LABEL”）以及按钮（“BUY_STOP_BTN”、“SELL_STOP_BTN”、“BUY_LIMIT_BTN”、“SELL_LIMIT_BTN”、“PLACE_ORDER_BTN”、“CANCEL_BTN”、“CLOSE_BTN”）。
最后，我们调用ChartRedraw函数刷新图表，确保删除操作后界面保持整洁。此外，在显示工具时，我们还需要考虑悬停效果，以确保其保持突出性。
//+------------------------------------------------------------------+ //| Show control panel | //+------------------------------------------------------------------+ void showPanel() { // Ensure panel is in foreground ObjectSetInteger(0, PANEL_BG, OBJPROP_BACK, false); //--- Show panel background ObjectSetInteger(0, PANEL_HEADER, OBJPROP_BACK, false); //--- Show panel header ObjectSetInteger(0, LOT_EDIT, OBJPROP_BACK, false); //--- Show lot edit field ObjectSetInteger(0, PRICE_LABEL, OBJPROP_BACK, false); //--- Show price label ObjectSetInteger(0, SL_LABEL, OBJPROP_BACK, false); //--- Show SL label ObjectSetInteger(0, TP_LABEL, OBJPROP_BACK, false); //--- Show TP label ObjectSetInteger(0, BUY_STOP_BTN, OBJPROP_BACK, false); //--- Show Buy Stop button ObjectSetInteger(0, SELL_STOP_BTN, OBJPROP_BACK, false); //--- Show Sell Stop button ObjectSetInteger(0, BUY_LIMIT_BTN, OBJPROP_BACK, false); //--- Show Buy Limit button ObjectSetInteger(0, SELL_LIMIT_BTN, OBJPROP_BACK, false); //--- Show Sell Limit button ObjectSetInteger(0, PLACE_ORDER_BTN, OBJPROP_BACK, false); //--- Show Place Order button ObjectSetInteger(0, CANCEL_BTN, OBJPROP_BACK, false); //--- Show Cancel button ObjectSetInteger(0, CLOSE_BTN, OBJPROP_BACK, false); //--- Show Close button // Reset button hover states buy_stop_hovered = false; sell_stop_hovered = false; buy_limit_hovered = false; sell_limit_hovered = false; place_order_hovered = false; cancel_hovered = false; close_hovered = false; header_hovered = false; // Reset button colors ObjectSetInteger(0, BUY_STOP_BTN, OBJPROP_BGCOLOR, clrForestGreen); ObjectSetInteger(0, BUY_STOP_BTN, OBJPROP_BORDER_COLOR, clrBlack); ObjectSetInteger(0, SELL_STOP_BTN, OBJPROP_BGCOLOR, clrFireBrick); ObjectSetInteger(0, SELL_STOP_BTN, OBJPROP_BORDER_COLOR, clrBlack); ObjectSetInteger(0, BUY_LIMIT_BTN, OBJPROP_BGCOLOR, clrForestGreen); ObjectSetInteger(0, BUY_LIMIT_BTN, OBJPROP_BORDER_COLOR, clrBlack); ObjectSetInteger(0, SELL_LIMIT_BTN, OBJPROP_BGCOLOR, clrFireBrick); ObjectSetInteger(0, SELL_LIMIT_BTN, OBJPROP_BORDER_COLOR, clrBlack); ObjectSetInteger(0, PLACE_ORDER_BTN, OBJPROP_BGCOLOR, clrDodgerBlue); ObjectSetInteger(0, PLACE_ORDER_BTN, OBJPROP_BORDER_COLOR, clrBlack); ObjectSetInteger(0, CANCEL_BTN, OBJPROP_BGCOLOR, clrSlateGray); ObjectSetInteger(0, CANCEL_BTN, OBJPROP_BORDER_COLOR, clrBlack); ObjectSetInteger(0, CLOSE_BTN, OBJPROP_BGCOLOR, clrCrimson); ObjectSetInteger(0, CLOSE_BTN, OBJPROP_BORDER_COLOR, clrBlack); ObjectSetInteger(0, PANEL_HEADER, OBJPROP_BGCOLOR, C'050,050,050'); // Reset panel state update_Text(PRICE_LABEL, "Entry: -"); //--- Reset entry label text update_Text(SL_LABEL, "SL: -"); //--- Reset SL label text update_Text(TP_LABEL, "TP: -"); //--- Reset TP label text update_Text(PLACE_ORDER_BTN, "Place Order"); //--- Reset Place Order button text selected_order_type = ""; //--- Clear selected order type tool_visible = false; //--- Hide tool ChartSetInteger(0, CHART_EVENT_MOUSE_MOVE, true); //--- Ensure mouse move events are enabled ChartRedraw(0); //--- Redraw chart }
我们对“showPanel”函数进行优化，以管理工具控制面板的显示与状态重置，同时整合新引入的“PANEL_HEADER”及悬停状态管理功能，从而提升工具的交互性。首先，我们使用ObjectSetInteger函数将面板背景（“PANEL_BG”）、新添加的标题栏（“PANEL_HEADER”）、手数输入框（“LOT_EDIT”）、价格相关标签（“PRICE_LABEL”、“SL_LABEL”、“TP_LABEL”）以及所有按钮（“BUY_STOP_BTN”、“SELL_STOP_BTN”、“BUY_LIMIT_BTN”、“SELL_LIMIT_BTN”、“PLACE_ORDER_BTN”、“CANCEL_BTN”、“CLOSE_BTN”）的OBJPROP_BACK属性设置为false，确保这些面板元素均显示在图表的前景层。
为保持界面整洁且可预测，我们通过将布尔变量“buy_stop_hovered”、“sell_stop_hovered”、“buy_limit_hovered”、“sell_limit_hovered”、“place_order_hovered”、“cancel_hovered”、“close_hovered”及“header_hovered”均重置为false，来清除所有残留的悬停效果，确保面板显示时无任何悬停状态遗留。
随后，我们使用“ObjectSetInteger”函数将按钮和标题栏的默认视觉外观恢复为原始颜色：将“BUY_STOP_BTN”和“BUY_LIMIT_BTN”的OBJPROP_BGCOLOR设置为“clrForestGreen”，将“SELL_STOP_BTN”和“SELL_LIMIT_BTN”设置为"clrFireBrick"，将“PLACE_ORDER_BTN”设置为“clrDodgerBlue”，将“CANCEL_BTN”设置为“clrSlateGray”，将“CLOSE_BTN”设置为“clrCrimson”，并将“PANEL_HEADER”设置为深灰色（“C'050,050,050'”）。
我们还将所有按钮的OBJPROP_BORDER_COLOR设置为“clrBlack”，以确保它们呈现一致的非悬停状态外观。
为了重置面板的功能状态，我们调用“update_Text”函数，将“PRICE_LABEL”设置为“Entry: -”、“SL_LABEL”设置为“SL: -”、“TP_LABEL”设置为“TP: -”，并将“PLACE_ORDER_BTN”设置为“Place Order”（下单），以清除任何先前的交易设置信息。我们清空“selected_order_type”变量，确保没有预先选中的订单类型，将“tool_visible”设置为false，以隐藏图表工具，并使用ChartSetInteger函数启用CHART_EVENT_MOUSE_MOVE事件，确保面板已准备好进行悬停和拖动交互。
最后，我们调用ChartRedraw函数刷新图表，使面板呈现默认状态，为下一次交互做好充分准备。编译后，结果如下：
由可视化效果可见，我们能够通过价格工具动态验证订单，并在价格超出范围时改变其颜色，从而提醒用户。此外，我们还可以动态拖动面板和价格工具，当鼠标悬停在按钮上时，能够获取其范围，并根据按钮范围动态改变颜色，从而实现我们的目标。接下来，只需测试项目的交互性即可，这部分内容在前文所述章节中体现。
