Here is a daily lifted from investing.com - a free resource that isn’t too bad wrg to charts. This daily is showing 15minute bars fwiw. You need to select the UK data (NICKELc1) for LME. From memory this pricing is reflective of the 3mth futures contract - not spot, but a direct derivative of it - it’s a good place to start (as far as publicly accessible/free resources are concerned) if you want to follow Ni pricing a bit closer. The downloadable app is pretty handy for quick reference, advertising is a bit annoying.
