Quick definition
A three-strike options structure that profits when the underlying pins near the middle strike at expiration. A butterfly is a defined-risk, low-cost pinning bet.
Payoff geometry
The maximum profit is the strike width minus the net debit paid, and it happens only if the underlying finishes exactly at the middle strike. Any deviation reduces P&L; a large move in either direction results in the small net debit as maximum loss. The butterfly is the cheapest available way to express a specific-price pin thesis.
When traders use it
Butterflies are common around expected pin levels — round-number strikes, gamma pins, or high-open-interest strikes near expiration. They are also common as follow-on structures after a directional move, when a trader wants to bet on consolidation. The trade-off is precision: the underlying has to land in a narrow range to pay off well.
How Treeova uses it
Butterflies on Treeova are typically constructed by short-dated pinning agents that combine the structural setup with Kronos market-intelligence signals — high open interest at a strike, options-flow concentration, or dealer-hedging analysis. The Adaptive Risk Engine treats the butterfly's asymmetric payoff explicitly rather than applying a symmetric-stop rule that would mis-price the tails.
