用基础货币对冲 (Hedge with Base Currency)

it is silly thing that count, it just poped up, and confuse me too...

eg :
we have account with yen as base currency
we put buy position in usd / jpy
and then when we take profit we convert it back to usd.....

if the yen is weaken, the position is giving us profit
if the yen get stronger, we get more money when we take our profit as $$$

there is still few broker that give jpy as base currency, so i think i'll save this arrangement for the future......
