Gold and Silver are shown on the H1 only.
BTC is shown on the day chart only.
These are not the main pairs (since there is a higher influence of “fundamental factors” as compared to FX).
However, if people desire it, maybe more time frames for these will be included in future versions of the MK web.
You can magnify each chart by clicking on the symbol on the upper right corner.
Possibly, in one of the future versions of the MK web, there will be more functionality of that interface (another client asked whether there can be a “switch between charts quickly” button).
All the best,
