Entering or exiting the parts of a multi-leg position one at a time, hoping for a better net price and accepting the risk of not completing it.
Traders leg in to capture a move — selling the call side of a strangle after a rally, then the put side after a pullback, aiming for more credit than the package would have paid.
It sometimes works and it always adds risk. Between the two fills you hold a directional position you did not intend, and if the market keeps moving you complete the structure at a worse price or not at all.
Example: you want the XYZ $45/$55 strangle for $2.00 total. You sell the $55 call at $1.20 with XYZ at $50, planning to sell the $45 put at $0.90 on a dip. XYZ rallies to $53 instead. The put is now $0.45, your total credit is $1.65, and your short call is under pressure.

Buying a call: payoff at expiry. A 105-strike call bought for 3 loses that whole 3 if the price finishes at or below 105, breaks even at 108, then gains a dollar for every dollar higher. The loss is capped at the premium; the upside is not capped.Long straddle: payoff at expiry. A 100 call and a 100 put bought together for 8 make a V. A quiet market that ends near 100 costs the whole 8; the position only turns positive once the price finishes below 92 or above 108, whichever way it goes.
