Quote from CPTrader:
Let's say you came in on May 1 and expected the SPX OR ESM4 to trade between 1025 and 1145 for the month of May. Esm4 opend on may 1 around 1106.
You want to create a position that will profit if your market view of this range is right, while being as much as possible delta and vol neutral. You also want to be out of the position some time during May or by the end of the month at the latest. The position should also be a "limited risk position". What would be the ideal position?
Long or short gamma? Where is the peak of the P&L distribution? That's an impossible task for short gamma/+expectation. If you were to sell deep otm call and put spreads the credit received would be miniscule.
