download history data of GBPUSD one minute

[A-S]

Hello

I developed an expert and I want to test it for the past year but I have data of a month back.

How can I get the last year's GBPUSD history data of one minute

My broker said it had nothing to do with him.

And I tried to download from a few sites but it came out inaccurate ?
