1) To multiply a "negative" by a "negative" gives a "positive".Quote from spindr0:

I'm not familiar with treasury futures or their options so I may be assuming a lot. Be that as it may, your quotes seem bizarre to me. How do you get 9 more pts of premium for a strike only one point higher? Bad quotes or some multiplier involved?
To answer your question, check the deltas of the two options. If the delta of the 117p is more than 1/2 that of the 118p, you're going to lose if your ratio spread drops immediately because the extrinsic loss on the 117p will exceed the intrinsic gain of the 118p. The more it drops, the more delta you lose.
It's possible that if it drops soon and keeps dropping, you may never see breakeven (look at a time series risk graph).

Hi Guys, new to the forum and kind of new to options trading
I saw the following trade done on 10yr treasury futures on friday
Buy 500 put 118.0 @18
Sell 1000 put 117.0 @ 9
i think at the time the market was trading around 119.0
Now my question is, with this trade being bought for flat, where is the risk ? i see the obvious risk of that if the trade falls below the 116 breakeven then it starts to lose money, but surely the trader could just unwind the trade somewhere between 118-117 ? What greek risk does this trade hold ?
Thank You
