Richard Jehl: I have questions about using previous MT4
versions for backtesting. I found on internet old MT4 terminals, and I succeeded in creating a suggested patch allowing the
old build 950 not to automatically update. It should be compatible with
my also-old Tickstory software version, and I also succeeded in exporting data to the
terminal, and to launch it with Tickstory. So everything looks fine but...I am unable to have any
chart/symbol at all on the terminal. And in the strategy tester I have
zero choice in the pair to test, despite the .fxt files are in the
correct folder for the EURUSD pair and that were correctly exported. I can see the
products I purchased in the past in the Market section but I can't
download any of them again...
Well, will it be possible to use this previous MT4 terminal for testing at all ? And is it totally impossible to use previous versions to look at current charts ?
Very old versions/builds of MT4 are no longer supported neither by MetaQuotes nor by the Brokers.
There is no need or advantage to using old versions/builds for back-testing. Use the current builds for that!
Also, the very old (free) version of TickStory has many bugs, so upgrade to a the latest paid version which has a very reasonable price.
