In the real world, it's not so straight forward. There are frequent false moves.
Here is an example. This is Hong Kong stock.

In order to avoid these kind of traps, let it form a longer base.
hello all,
So.. I am often playing with pseudo-fly structures which have the maximum payoff at a certain strike and lose at the wings. I usually have a defined profit target at 25% of the maximum payoff, which seems a reasonable rule of thumb.
It happened however many times that the structure immediately gained 15%~20%, then went back almost to zero, then after one month finally reached the target. Clearly, in hindsight, had I taken immediately 15% that would have been a much better allocation of my capital.
So at this point I'm wondering: anyone here came up with some useful heuristic that links elapsed time and profit target? Care to share?

summing what your gamma/theta pnl should have been from inception to now. alternatively, how much of your pnl has come from vega/delta. If most of your pnl is vega/delta then you might want to cut. if it's inline with the gamma/theta then your thesis might still be intact.

Great question,and I wrestle with the same issue all the time..
I used to look at Delta/Theta,while also valuing the fly structure on my chosen flat vol to see if I had "edge"..
Nowadays,I look at Orats D%,common sense and gut feel...
Like you,I look at max gain vs max risk.
On short dated flys,I typically start scaling out at 25% of max gain,and rarely have much left at 50 percent..
As you may guess,I don't pay much for these structures,and on split strike flys I am quick to buy the imbedded short verticals..
Fwiw,I'm sure Des can offers some valuable insight..
Oh I see.. thanks a lot for all the insight. When you say "split strike" you mean "skip strike"?

Why 25%?
Why not more or less than 25%?
Is your expected profit 25% every time you open a trade?
