It depends on the money you have left on your account.

Right now the EURJPY is going up, but it will come down sooner or later.

If you still have enough money to keep on trading, you can afford to wait.  Otherwise, it's better to close the trade and look forward to other trades.

A Fibo retracement can lead the EURJPY back to the 163.00 level.  Maybe you should place your Min Exit there, and close wxith a smaller loss than you have right now.  But there is still the risk that it will go higher first, before retracing, so this depends on your balance as well.

The decision is yours,
