Start with assignment
Only consider a strike where owning the shares would be acceptable. Premium does not make an unwanted assignment a good outcome.
Use the chart first
Review trend, important support, Volume Profile location, event risk, and liquidity before looking at premium. High implied volatility alone is not a reason to sell a put.
Know the obligation
The position can lose money if the underlying falls. Assignment, capital tied up, spread quality, and expiration all matter.
Advanced takeaway
A cash-secured put is a risk-defined process only when the collateral, strike, assignment, and chart all make sense together.
