Short-Dated Options: Lower Premium, Faster Delta and Theta Changes
Summary
This exchange article explains how option time to expiry affects premium and short-term trading use. Options with only a day or two remaining generally carry less time value, making them comparatively inexpensive instruments for hedging events or expressing a view on a near-term move. Longer-dated options have more time value because there is more time for the underlying price to move in the option’s favor.
The trade-off is that short-dated options can change rapidly as expiry approaches. Delta can rise when Bitcoin nears the strike, increasing both potential gains and losses. Theta decay is also greater, particularly for out-of-the-money options, whose chance of expiring in the money diminishes with time. The article also notes that delivery fees are not charged when these daily options are held to expiry. It offers qualitative guidance rather than a pricing model or strategy evaluation, and does not quantify the risks beyond the stated fee.
