Disliked{quote} I've written a Windows program that creates HST files from CSV files. Based on the file format I found at https://www.mql5.com/en/forum/149178. When I open offline the newly created HST file NT4 says its WAITING for update. I have compared my HST file to an HST file created by your script and I do not see an obvious difference (other than your script uses 44 bytes instead of 60 for the Rate record). Do you have any idea why I am getting this message? If I can get this program working then I would like to make it available to users...Ignored
I don't really know, I'd just try to restart MT4 afterwards and/or copying the HST file into the correct folder inside of MT4.
