Im having issues with my mql5 script to get the previous days high and low and display it on the next day along with the 25%, 50% and 75%. The high and low sometimes don't cover the entire day and the percentages dont display at all. Also i would like a vertical line to connect all together like a box. i'm unsure how to do this. void OnStart() { // Define variables double high, low; datetime startTime, endTime; int range; int i = 1; // Start from the previous day // Loop through the previous days while (true) { // Get the high and low of the previous day high = iHigh(NULL, PERIOD_D1, i); low = iLow(NULL, PERIOD_D1, i); range = int(high - low); //Calculate the percentile double P_25, P_50, P_75; P_25 = NormalizeDoubleFunction((low + (range * 25/100))); P_50 = NormalizeDoubleFunction((low + (range * 50/100))); P_75 = NormalizeDoubleFunction((low + (range * 75/100))); double point = SymbolInfoDouble(_Symbol, SYMBOL_POINT); startTime = iTime(NULL, PERIOD_D1, i) + 24 * 60 * 60; // Start time is the next day endTime = startTime + 24 * 60 * 60; // End time is the end of the next day // Break the loop if no more data if (startTime == 0) break; // Draw lines on the chart string highLineName = "PrevDayHigh_" + IntegerToString(i); string lowLineName = "PrevDayLow_" + IntegerToString(i); string P_25_Name = "25%" + IntegerToString(i); string P_50_Name = "50%" + IntegerToString(i); string P_75_Name = "75%" + IntegerToString(i); string startVertical = "Start vertical"; string endVertical = "End Vertical"; ObjectCreate(0, highLineName, OBJ_TREND, 0, startTime, high, endTime, high); ObjectSetInteger(0, highLineName, OBJPROP_COLOR, clrRed); ObjectSetInteger(0, highLineName, OBJPROP_WIDTH, 1); ObjectSetInteger(0, highLineName, OBJPROP_STYLE, STYLE_SOLID); ObjectCreate(0, P_25_Name, OBJ_TREND, 0, startTime, P_25, endTime, P_25); ObjectSetInteger(0, P_25_Name, OBJPROP_COLOR, clrBlue); ObjectSetInteger(0, P_25_Name, OBJPROP_WIDTH, 1); ObjectSetInteger(0, P_25_Name, OBJPROP_STYLE, STYLE_SOLID); ObjectCreate(0, P_50_Name, OBJ_TREND, 0, startTime, P_50, endTime, P_50); ObjectSetInteger(0, P_50_Name, OBJPROP_COLOR, clrYellow); ObjectSetInteger(0, P_50_Name, OBJPROP_WIDTH, 1); ObjectSetInteger(0, P_50_Name, OBJPROP_STYLE, STYLE_SOLID); ObjectCreate(0, P_75_Name, OBJ_TREND, 0, startTime, P_75, endTime, P_75); ObjectSetInteger(0, P_75_Name, OBJPROP_COLOR, clrOrange); ObjectSetInteger(0, P_75_Name, OBJPROP_WIDTH, 1); ObjectSetInteger(0, P_75_Name, OBJPROP_STYLE, STYLE_SOLID); ObjectCreate(0, lowLineName, OBJ_TREND, 0, startTime, low, endTime, low); ObjectSetInteger(0, lowLineName, OBJPROP_COLOR, clrGreen); ObjectSetInteger(0, lowLineName, OBJPROP_WIDTH, 1); ObjectSetInteger(0, lowLineName, OBJPROP_STYLE, STYLE_SOLID); i++; } } //+------------------------------------------------------------------+ double NormalizeDoubleFunction(double value){ double point = SymbolInfoDouble(_Symbol, SYMBOL_POINT); return NormalizeDouble(value/point, 0) * point; }
