Statistics of candles – script MetaTrader 5

Counting the number of series of bullish and bearish bars. Displaying the result as a chart. Saving the screenshot of the resulting chart. The script uses the CGraphic class.

Input Parameters

• Count of bars – the number of bars (from the rightmost bar on the chart), for which the calculation will be preformed;
• Verification – the flag for printing the copied timeseries of this symbol and the resulting array of bar series. NOTE: should only be enabled if the Count of bars parameter does not exceed 15-30. Otherwise the amount of printed data will be very large;
• Save screenShot – enable/disable saving of screenshots of the resulting chart;
• Sleep (milliseconds) – a delay in displaying the resulting chart.

Series of bars are coded according to the following principle:

   enum ENUM_SERIES_TYPE
     {
      Bull=1,  // ↑
      Bear=-1, // ↓
     };

A “bullish” candlestick has the code of “1”, a “bearish” candlestick has the code of “-1”.

Another parameter for the name of the series is calculated as follows:

current series (ENUM_SERIES_TYPE) * the umber of bars in a row in this series
int name_series=current_series_type*count_series;

Note: the very last series is not included in calculations, because you cannot know how long the series will last.

Screenshots are saved (if Save screenShot is enabled) to [data folder]\MQL5\Files\Statistics of candles\. An example of a saved screenshots of the resulting charts. Series are drawn along the X axis, i.e. the “-5” series means five bearish bars in a row, and “2” means two bullish bars in a row:
