This should have failed.
I'm pretty darn sure I added a test to prevent this in the past, but I'm
stunned now that this passes, and I can't find the test!
That this doesn't output an error message, is a bug.
I'll make this fail now, you're not supposed to be allowed to use a
different price currency than the cost currency you're using.
In any case, when you use the cost, the price is ignored (other than to be
added to the prices database).
The "weight" of that posting against the rest is that which is used and it
is inferred by the cost only.

Because the price is ignored (desired).

You can make the other posting priced in USD (not supported in Ledger BTW,
if I recall correctly).
It sort of makes sense because how else can the gain be calculated?

Yep.

This works:
2018-03-21 * "Convert MR to KrisFlyer"
Assets:Test -100 MR {0.0075 USD}
Assets:Krisflyer 100 KRISFLYER @ 0.007500 USD
This too:
2018-03-21 * "Convert MR to KrisFlyer"
Assets:Test -100 MR {0.0075 USD}
Assets:Krisflyer 100 KRISFLYER @ USD
Maybe my transactions are not right because of my ledger-mindset

I'd be more confused if I had two different syntaxes which do the same
thing if you ask me...
- prices are used for price conversions (e.g., currencies)
- costs are used only when you need to track the cost basis (e.g.,
investments)
That's it.
