This is not about where you get
your edge or what is someone's edge
(method , market maker or floor
trading)
BUT about a mathematical method
to relate a number with the word
"edge"....
A lot of nice words BUT how do you
quantify the edge based on the

even with a negative expectancy, you
can have an edge even if it doesn't
make you money....
take the E-mini S&P for example.
no edge - random buying and selling
with market orders ; expected average
trade will be -0.25 = the spread
