Generic algorithm for finding B/E points in spot range

[earth_imperator]

I first tried to use bsearch algorithm for locating the point where PnL for a complex position
(ie. which can have more than 1 leg) becomes about 0, but then learned the hard way that there can be more than one B/E point
How best to find such B/E points in an efficient manner with 4 decimals for the spot?
Can one still use such a fast algorithm like the bsearch one?
Anybody done such a thing?

mkt price - vwap = pnl
solve for pnl = 0

Wrong answer!

I already have an idea...

why? OG question was nonsense.
the answer is subtraction. if you're up 5000 then break even is price where you don't have 5000 anymore.

Watch the PnL diagram consisting of 2 wonderful bosoms
It means there are 2 B/E points: left and right from the current spot (100) :

Good thinking\ i was wanting a chart\ prefer a candle chart but a mountain\ valley is ok.
