Iron Butterfly

Use an iron butterfly when you have high conviction the stock will finish at a specific price (pin). You get higher credit/maximum profit than an iron condor, but you have a narrower profit zone. It's a higher risk/reward trade-off.

Unlikely - max profit requires the stock to finish EXACTLY at your center strike. Realistically, you should target 25-50% of maximum profit. The stock rarely pins perfectly.

Your profit decreases rapidly as the stock moves away from center. At the breakeven points, you have zero profit. Beyond the breakevens, you start losing money up to the maximum loss.

In a way, yes. While both have defined maximum loss, the iron butterfly has a much narrower profit zone and higher gamma. Your probability of any profit is lower, but your maximum profit is higher.

Pins most commonly occur at options expiration, especially monthly expirations. Stocks with high open interest at certain strikes, round numbers, and those at max pain levels are more likely to pin.

Look for: 1) High open interest at specific strikes, 2) Max pain alignment, 3) Technical support/resistance at the level, 4) Round numbers ($100, $150, etc.), 5) Low recent momentum. Confluence of multiple factors increases probability.

Generally no. Gamma risk becomes extreme in the final days, making P/L very unpredictable. Most traders close by 7-14 DTE unless the stock is pinned perfectly and they're comfortable with expiration risk.

Close one of your short ATM options and resell it at an OTM strike. For example, if your center is $580, you might close the short $580 call and sell a $595 call instead. This widens your profit zone.

Wider wings = higher credit but higher max loss. Narrower wings = lower credit but lower max loss. The trade-off is risk vs. reward. Most traders use $5-10 wings for stocks and $25-50 for indices.

High IV inflates the straddle you're selling at the center, giving you more credit. More credit means wider breakevens and lower max loss. In low IV, the credit may not justify the narrow profit zone risk.

High positive GEX indicates market makers will stabilize price (buy dips, sell rips), creating favorable conditions for pin plays. Negative GEX means they'll amplify moves. Enter iron butterflies when GEX is high and positive.

Enter Tuesday or Wednesday of expiration week at max pain or highest OI strike. Monitor daily. Close Friday morning before final hour volatility unless perfectly pinned. Very high theta but extreme gamma risk.

For American-style options (equity), ATM options have significant assignment risk. Use SPX (European, cash-settled) for no assignment risk. For equity options, be prepared to manage stock assignment if exercised early.

When the stock has moved significantly but you still believe it will stay on that side. Moving the losing wing closer reduces or eliminates risk on that side while accepting more risk on the other. It's a directional adjustment to a neutral position.

Need historical options data including pin frequency by strike/OI. Key metrics: pin rate at high OI strikes, average P/L at various profit targets, max drawdown, and win rate. Filter for high probability setups only.
