when I try to download history for gbp/jpy it says there is no more to download but I only have a few days worth of history. Is there a website where I can download a zip of all the history of this pair or other pairs? I tried at alpari and it says the download is not available.
Alpari is the only one I know of. You can always get an Alpari demo account and use it. When you scroll back it should download the data automatically, whether the download on the website is available or not.
I can scroll my Alpari GBP/JPY 4H chart all the way back to 1999. 
thanks Phil, I’m using ibfx, but I’ll give alpari a try
