MT4 Import External Data and Export .csv files Script/Ea

Hi.

Provided that linked Script and EA do this: 

A- "Load Stock Data" -when excecuted manually- imports end-of-day financial data from Yahoo Finance into the platform's 'History' tab (.hst format) so that the  data can be imported into daily offline charts

 https://forum.mql4.com/52872

B - "Currency Loader" automatically exports .csv files of a certain Symbol (i.e. security) from different timeframes to MT4 folder Files/Export_History every 'x' seconds 

https://www.mql5.com/en/code/8102 

Here is my request:

-> to code a single script/ea that can unite the essential functions of both of them in order to achieve the following goals:

1) to be applied to OFFLINE Daily charts

2) so that those charts automatically get their data updated once a day 

3) and after the update is completed it should be able to export a single .csv file for every Symbol (or chart) formatted -if possible- such as this:

1st row Symbol_Name,,,,,

2nd row Date,Open,High,Low,Close,Volume  

for example:

SPY.US,,,,,

20151003,2020.40,2056.84,2011.73,2034.42,156890

Please note that:

i- COMMA (,) separator for .csv files 

ii- Symbol may have also extensions like these.... %5EVIX or SPM.MI so the header must be flexible enough

iii- All the securities from external import require 2 DECIMAL DIGITS only 

Feel free to write me for any further explanation or request.

Thanks.
