How it is built
- Sell an out-of-the-money put and buy a lower put.
- Sell an out-of-the-money call and buy a higher call.
- Max profit = credit received. Max loss = width of one spread minus the credit.
Managing it (examples, not advice)
- Many traders take profits at 50% of the credit.
- Gamma walls and the expected move help place the short strikes.
- Close or adjust if price tests a short strike instead of hoping.
