Yesterday, I conducted following AUD/JPY "carry trade" experiment - real money, but educational purpose :)

In 23:55, I bought 200,000.00 AUD/selling ~21,512,000 JPY.
For the operation, my broker blocked ~1,276.00 EUR from my account.

In the midnight, I received carry trade interest of 2,520 JPY.
This is 23.42 AUD or 14.94 EUR, or 1.17 % of the blocked money for 1 day only.

Later on, I closed the possition, and I had my ~1,276.00 EUR unblocked.
