Chart Properties

Identifiers of ENUM_CHART_PROPERTY enumerations are used as parameters of functions for working with charts. The abbreviation of r/o in the “Property Type” column means that this property is read-only and cannot be changed. The w/o abbreviation in the “Property Type” column means that this property is write-only and it cannot be received. When accessing certain properties, it’s necessary to specify an additional parameter-modifier (modifier), which serves to indicate the number of chart subwindows. 0 means the main window.

For functions ChartSetInteger() and ChartGetInteger()

ENUM_CHART_PROPERTY_INTEGER

The value is required for converting the absolute coordinates of the main chart to the local coordinates of a subwindow for correct work with the graphical objects, whose coordinates are set relative to the upper left corner of the subwindow frame. | int r/o modifier - subwindow number | | CHART_FIRST_VISIBLE_BAR | Number of the first visible bar in the chart. Indexing of bars is the same as for timeseries. | int r/o | | CHART_WIDTH_IN_BARS | Chart width in bars | int r/o | | CHART_WIDTH_IN_PIXELS | Chart width in pixels | int r/o | | CHART_HEIGHT_IN_PIXELS | Chart height in pixels | int modifier - subwindow number | | CHART_COLOR_BACKGROUND | Chart background color | color | | CHART_COLOR_FOREGROUND | Color of axes, scales and OHLC line | color | | CHART_COLOR_GRID | Grid color | color | | CHART_COLOR_VOLUME | Color of volumes and order opening levels | color | | CHART_COLOR_CHART_UP | Color for the up bar, shadows and body borders of bull candlesticks | color | | CHART_COLOR_CHART_DOWN | Color for the down bar, shadows and body borders of bear candlesticks | color | | CHART_COLOR_CHART_LINE | Line chart color and color of “Doji” Japanese candlesticks | color | | CHART_COLOR_CANDLE_BULL | Body color of a bull candlestick | color | | CHART_COLOR_CANDLE_BEAR | Body color of a bear candlestick | color | | CHART_COLOR_BID | Bid price level color | color | | CHART_COLOR_ASK | Ask price level color | color | | CHART_COLOR_LAST | Line color of the last executed deal price (Last) | color | | CHART_COLOR_STOP_LEVEL | Color of stop order levels (Stop Loss and Take Profit) | color | | CHART_SHOW_TRADE_LEVELS | Displaying trade levels in the chart (levels of open orders, Stop Loss, Take Profit and pending orders) | bool | | CHART_DRAG_TRADE_LEVELS | Permission to drag trading levels on a chart with a mouse. The drag mode is enabled by default (true value) | bool | | CHART_SHOW_DATE_SCALE | Showing the time scale on a chart | bool | | CHART_SHOW_PRICE_SCALE | Showing the price scale on a chart | bool | | CHART_IS_OFFLINE | Flag, indicating that chart opened in offline mode | bool r/o |

For functions ChartSetDouble() and ChartGetDouble()

ENUM_CHART_PROPERTY_DOUBLE

For functions ChartSetString() and ChartGetString()

ENUM_CHART_PROPERTY_STRING

Example:

int chartMode=ChartGetInteger(0,CHART_MODE);
   switch(chartMode)
     {
      case(CHART_BARS):    Print("CHART_BARS");   break;
      case(CHART_CANDLES): Print("CHART_CANDLES");break;
      default:Print("CHART_LINE");
     }
   bool shifted=ChartGetInteger(0,CHART_SHIFT);
   if(shifted) Print("CHART_SHIFT = true");
   else Print("CHART_SHIFT = false");
   bool autoscroll=ChartGetInteger(0,CHART_AUTOSCROLL);
   if(autoscroll) Print("CHART_AUTOSCROLL = true");
   else Print("CHART_AUTOSCROLL = false");
   int chartHandle=ChartGetInteger(0,CHART_WINDOW_HANDLE);
   Print("CHART_WINDOW_HANDLE = ",chartHandle);
   int windows=ChartGetInteger(0,CHART_WINDOWS_TOTAL);
   Print("CHART_WINDOWS_TOTAL = ",windows);
   if(windows>1)
     {
      for(int i=0;i<windows;i++)
        {
         int height=ChartGetInteger(0,CHART_HEIGHT_IN_PIXELS,i);
         double priceMin=ChartGetDouble(0,CHART_PRICE_MIN,i);
         double priceMax=ChartGetDouble(0,CHART_PRICE_MAX,i);
         Print(i+": CHART_HEIGHT_IN_PIXELS = ",height," pixels");
         Print(i+": CHART_PRICE_MIN = ",priceMin);
         Print(i+": CHART_PRICE_MAX = ",priceMax);
