Those who Want to Trade the Pair.
You can see the MAX COI at 6100PE-6150CE.
The combined Premium is at 15.5.
Now two things can happen.
1. For the entire day market Can trade in this Range of 6100-6150, in which case this pair should become worthless.
2. The Second thing is that, it has to BO/BD of this range, in which case the pair can give a Quick spike.
Those who believe in 1 can Sell this Pair.
Those who believe in 2 can Buy this Pair.
I will Buy this Pair at 15.5. Those who are buying, if there is movement on one side and one strike is in profit of say 10-15 points then close the strike and leave the other strike.
