Mql5官网 MEL Buffer Scan 外汇EA

Buffer Scan
analyzses your custom indicator buffers with iCustom function on a certain period of history (configurable by
the user) and writes buffers’s data to a csv file.The script helps determine buffers’
numbers, through which the indicator transfers any data, for example, the
appearance of arrows, a particular color, a certain line and other information. 

The utility scans all 512 indicator
buffers but it records to a csv file only those of them which have data. If a
buffer does not transfer anything to the chart, it is not written to the file. So only data of a few buffers are left in
the file.

Settings

• StartDate – start date for analysis (for
  example, 2017.01.10 00:00)
• EndDate – end
  date for analysis (for
  example, 2017.02.10 23:59)
• IndicatorName – indicator
  name without .ex4 file extension (for example, MyBestIndicator). The indicator should be in the root of MQL4\Indicators folder
  (without subfolders). Check if there are spaces at the start and at the
  end of the indicator file name (this happens very rarely). If there are some,
  remove them directly from the file name (change the name of the indicator file).
• FileName – name of the .csv file for the indicator data and the subfolder name where the
  indicator will be located. If you only write the file name, it will be located
  in the root of MQL4\Files directory. If you also write the name of a subfolder
  (for example, Mysubfolder\MyBestIndicator), the file will be located in
  MQL4\Files\Mysubfolder. You can write the file name without the .csv extension. If the
  file already exists and it is re-recording, it is necessary that it has not
  been opened in any program.

Note: The script automatically replaces the number 2147483647 (empty value) with
zero.
