Say you expected CAPAM to open to $60M. That would equate to a Put price of $7 ($5 above your purchase price of $2). If the Put got to $10 or $12, you might consider shorting it.
BUT, be wary about holding Puts short at halt. Because the most you can make is the amount you invest. OTOH, if the movie overperforms, the amount you lose is only limited by that overperformance.
There's a Help section at the bottom of every page. Reading through the entire glossary is most helpful.
