thanks for sharing your experience and looking forward to following and learning from this trade!!

my question at this point would be what's the rule for selecting the border numbers in this case are 770 and 870? (from the charts, looks 870 --> recent top and 770 in Apr--> recent low in Jan).

Also, is there a best entry point, e.g, waiting until RUT comes around middle of two borders (in this case, (870 - 770)/2 + 770 = 830) or when its premium increased? .

I would also like to know additional selecting conditions for iron-butterfly trading candidates, e.g., do we need to find high/high liquidity volatile securities? positioning or avoiding for ERs ? etc.

Thanks!
