Given the current level, we are not to far frow the beginning of our profit zone.


I - The situation :

EUR / USD doesn't want to cross 1.34.




II - The strategy :

I had choosen in a arbitrary way a bearish direction on the EUR / USD, that the dollar should strengthen against the EUR.
The butterfly spread is built as it follows:

DEC 28 Expiry:
- The purchase of 300000 calls struck at 1.34 for $0.0230 each ( Implied Volatility 16.59% ) hence a debit of $ 6900
- The short selling of 600000 calls struck at 1.32 for 0.0169 each ( Implied Volatility 16.72% ) hence a credit of $ 10140
- The purchase of 300000 calls struck at 1.30 for $ 0.0138 ( Implied Volatility 17.86% ) hence a debit of $ 4140

Global debit : $ 900



III - Pricing :




300000 1.34 puts are worth 0.0199 each ( Implied Volatility de 14.95% ) hence $ 5970 ( $ - 930 )
600000 1.32 puts are worth 0.0144 each ( Implied Volatility 116.30% ) thus $ 8640 ( $ + 1500 )
300000 1.30 puts are worth 0.0089 each ( Implied Volatility 16.40% ) hence $ 2670 ( $ - 1470 )

Global P&L : - 930 + 15000 - 1470 = $ - 900



IV - Graph :




Adjustment Pricing :
Our adjustment was :

Selling 300000 dec 1.34 calls for $ 6840
Buying 200000 dec 1.36 calls at 0.0317 for $ 6340.

It's now worth :
- 300000 1.34 puts at 0.0199 thus $ 5970$ (+ 870)
- 200000 1.36 puts at 0.0287 thus 5740$ ( - 600)

A profit of $ + 270.
