Need guidance about Oanda

I am using Oanda and make trades in e/u. The problem is:

Lets say i am long in e/u at 1.49.

Now lets say i want to short e/u 1.53 levels. As soon as i enter my short order, Oanda closes my long position by those many units/lots.

I dont want to close my long position at 1.49.

I want to take a fresh short position at 1.53. How can i do that without closing my earlier long position?

There is no margin issue or funds. Enough margin and funds are there to take a fresh new short position without closing the earlier long position.

Any help will be appreciated.

It doesn't work like that on Oanda. You can only do that if you place your short trade in a separate sub-account. All trades in the same account will be netted.

right...

I have to create a sub account and short in the sub account.
