A collar trade is a covered call writing-like trade where a protective put is added to the long stock and short call positions. This podcast used a hypothetical example to enter a collar trade, then close and re-sell the short call. 3 columns of the BCI Collar Calculator are used to reflect the initial trade entries as well as the trade adjustments.
