As changed named suggest, scope for this thread is unlimited. What i was trying to post as continuation from 1st post, is now on hold for some time, cause of an interesting setup i read in F&O Magizine Oct Issue. Its a Double Butterfly System applied on S&P 500. I compiled some aspect for reference to apply on NF.
Good thing is its backtested well for 5 years
Now, with NF some limitations arises due to
a) strikes available at 50
b) Liquidity might not facilitade good exacution in Middile month options.( point no 7 in first diagram--- second month options ???)
c) Resources limited to Options Oracle.
Here are two setups with same strikes but one in Oct and other in Nov.
However point 7 advocate for options used as second expiration month, but i could not find benefits of Nov setup except more time. Rather Oct has lower cost and both setups have almost near zero position delta at start.
Another flip side for Nov seems ,
1) Higher negative vega ( compared to Oct ) and this causes net position to erode if volatility increases at present.
2) Lower Positive Theta ( compared to Oct ) and this makes written option legs to loose premium at low effective rate.
