Call Credit Spread Enabled
Setting key
call_credit_spread_enabled
Default
ON
What it does
Enables the call credit spread structure (short call + long call above it). A call credit spread is a bearish to neutral defined-risk structure that collects premium when the underlying stays below the short strike. Used by the mechanical, earnings, and contraction engines as a one-sided alternative to the iron condor.
When to change it
Turn OFF if you want to avoid single-sided call spreads. In most cases leave ON.
Safe range
ON or OFF.
Example
After a gap-up in NVDA, the call side has rich premium. The contraction engine enters a call credit spread. With call_credit_spread_enabled OFF, this entry is skipped.
