Spread Data Logger

Spread Data Logger

Spread Logger consists of two indicators:

Spread Logger Write – Creates a CSV file containing spread data as a function of time. This is done in real-time.

Spread Logger Read – Reads CSV file created, displays some stats, & draws collected data to chart. Also, draws live spread data to chart.


Save both files in terminal\experts\indicators folder

Spread Logger Write:

Attach Spread Logger Write to any chart. (Insert > Indicators > Custom > Spread Logger Write)

Name your file under the inputs tab or leave the default filename.

Leave the MT4 terminal running and chart open for the time desired, Spread Logger will collect data in real-time.

Note: For the most accurate data, attach Spread Logger Write to a 1-Minute chart.


note: All files created by Spread Logger Write are saved to the terminal\experts\files folder.



Spread Logger Read:

Open chart of currency pair for which you have logged data & attach Spread Logger Read to chart. If you used a custom file name, make sure you type the file name correctly.

note: While you may attach Spread Logger Read to a chart of any timeframe, using a chart of the same timeframe for which you collected data will yield the best results visually.


Spread Logger Read will display some stats:

  • Time tested & number of bars tested
  • Mean spread
  • Mode & frequency of the mode as a percentage


If the time interval for which data was collected is within the range of the portion of the chart currently being displayed, you will see the spread data you collected drawn to the chart. The live spread will also be displayed as of the time Spread Logger Read was attached to the chart.
