It is better to test the supportive peaks at 89.06. There is no trading. The overnight holding cost is just 3 USD / Lot per business day (charging 5 days per week), so it is not too bad.
Selling re-setts up after the key technical support at 50 points below the open price is broken. The lucky thing is that only this key point is tested today. Good luck!
If there is no signals of testing the bottom at 87.45 at the beginning of US business hours, then it would not need to test it again which avoids testing cost --- 11.5 points float deficit.
