How are ENB butterfly max profit and max loss calculated?

Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the ENB butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 18.50%), the computed maximum profit is $194.78 per contract and the computed maximum loss is -$45.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a ENB butterfly?

The breakeven for the ENB butterfly priced on this page is roughly $52.95 and $57.05 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current ENB market-implied 1-standard-deviation expected move is approximately 5.30%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

Current ENB snapshot

As of May 15, 2026, spot at $55.17, ATM IV 18.50%, IV rank 17.21%, expected move 5.30%. The butterfly on ENB below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 245-day expiry.

Why this butterfly structure on ENB specifically: ENB IV at 18.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a ENB butterfly, with a market-implied 1-standard-deviation move of approximately 5.30% (roughly $2.93 on the underlying). The 245-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ENB expiries trade a higher absolute premium for lower per-day decay. Position sizing on ENB should anchor to the underlying notional of $55.17 per share and to the trader's directional view on ENB stock.

ENB butterfly setup

The ENB butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With ENB near $55.17, the first option leg uses a $52.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ENB chain at a 245-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 ENB shares for the stock leg in covered calls and collars).

Buy 1	Call	$52.50	$5.05
Sell 2	Call	$55.00	$3.50
Buy 1	Call	$57.50	$2.40

When traders use butterfly on ENB

Butterflies on ENB are pinning bets - traders use them when they expect ENB to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.

ENB thesis for this butterfly

The market-implied 1-standard-deviation range for ENB extends from approximately $52.24 on the downside to $58.10 on the upside. A ENB long call butterfly is a pinning play: it pays maximum at the middle strike if ENB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ENB IV rank near 17.21% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on ENB at 18.50%. As a Energy name, ENB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ENB-specific events.

ENB butterfly positions are structurally neutral / pin (limited-risk, limited-reward); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. ENB positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ENB alongside the broader basket even when ENB-specific fundamentals are unchanged. Always rebuild the position from current ENB chain quotes before placing a trade.
