I have decided to re install MT4 and download new data as my old data was corrupted.
While following the installation instructions I was led to an Alpari source of Data. This site apparently doesn’t offer data any more.
What currently is the best source of MT4 Data?
Thanks
Even if the Alpari site doesn’t offer data anymore you can still get it from Alpari. Just open an Alpari demo account, hit “F2” to open the MT4 History Center and download the data from there. Then export it, open your broker’s version of MT4, and import it. 
It’s complicated and annoying, but it’s always worked for me! And don’t forget to shift the time to match your brokers when you import!!
