2) RISING LINE:
If you are t+0 line is rising up , you may lose money if the market is sideways .
very poor breakevens.
Zero theta decay
High delta
Example: LONG STRADDLE
3) FLAT LINE: ( my personal set up)
If you are t+0 line is flatten , you may not lose in any the market situation till some extent.
Decent breakevens
Moderate Theta decay
Very low Delta
Example: PROTECTED IRON FLY
4) STEEP DOWNFALL:
If you are t+0 line is falling too steep , you may lose in unidirectional move.
Brilliant breakevens
High Theta decay
High Delta
Example: SHORT STRADDLE
