Quick definition
An options strategy combining a short put with a short call spread, designed to collect premium with no upside risk if structured properly.
Why traders use it
Jade lizards monetize both directional and volatility expectations. The trader is mildly bullish (or at least not bearish), expects IV to be range-bound or contract, and wants asymmetric risk: no upside loss possible if structured correctly, defined downside loss equal to the short put strike minus credit. It's a popular alternative to a naked put for traders who don't want unlimited upside-direction risk hedged by capping their tail.
Structural rule
Total credit collected must exceed the call-spread width. If you sell a $105/$110 call spread for $1.00 and a $95 put for $1.50, total credit is $2.50, which exceeds the $5 spread width? No — $2.50 < $5.00, so this example still carries upside risk. The structural rule must be checked at entry; Treeova's jade-lizard archetype refuses to open trades where the rule isn't satisfied.
How Treeova uses it
Jade-lizard agents target IV Rank above 40 (premium-rich environment) and underlyings with stable upside trend. The platform validates the no-upside-risk invariant at entry and refuses to enter the trade if the rule isn't met — the kind of structural check most manual traders forget to run.
