Can someone provide that ForceLoadHistoricalData_mod.mq4 for loading all chart data of all opened charts.

What I have is LoadAllHistory Script which compile in MT4 and loads all data from one chart. You should not apply the script to more than 10 (It depends little bit) charts at once. You can download the free source here :

Maybe Footon (?) could provide that file please. Thanks in advance, because I know from other thread in Premium section he got it.

Perhaps someone could modify that ForceLoadHistoricalData_mod.mq4 so that all data from marketwatch are downloaded step by step ? At the moment what I read is, that you have to open all the charts first. On more than 500 symbols e.g. that's time consuming.

Same to Popov's Export Data to CSV.mq4  script. You have to apply on each chart. Best is after ForceLoadHistoricalData Script that all data are downloaded from Marketwatch too with a modified Export Data to CSV.q4 script.

An ultimativ Export Data to CSV script would be if there is an option of overriding the old data or adding the new data to old data to keep database updated (and keep the older from Charts too). Because the brokers limit on bars from actual date counting and older data disappear.

Thanks in advance.
