Metal-Currency Accounts
I do not know where to publish the post, because it deals not so much the platform as more of the account.

in one company i saw a nice idea, about metals accounts ->

EXNESS metal-currency accounts include baskets of the following metals and currencies:

MAUUSD – Gold;
MAGUSD – Silver;
MPTUSD – Platinum;
MPDUSD – Palladium;
MBBUSD – Gold + Silver + Platinum + Palladium;
MBAUSD – EUR + USD;
MBCUSD – EUR + USD + GBP + JPY;
MBDUSD – Gold + Silver + Platinum + Palladium + EUR + USD + GBP + JPY.

Is it possible and whether it will be implemented in the future? Because I think everyone who is interested in preserving the resources will support this idea.

Thanks, and sorry for my english

The range of tradable instruments offered by Dukascopy is headed towards expansion. We are currently working on the extension of the lineup and metals are no exception.

We do as well remind that XAU and XAG are already available to our clients.

However, we cannot yet announce any precise terms of new instruments' releases.

Oh, no.. question was not about trading instruments.. no,

Right now the accounts can be opened in seven different currencies – USD, CHF, EUR, GBP, JPY, CAD, AUD

The question was as to why not give the opportunity to open an account in the currency of gold, silver, platinum, or their sum as a percentage.

It is very interesting idea.
