smaller spreads

In the past years, the markets have moved to decimalization reducing the spread size

but...

bid ask
23 1/4 23 13/50 spread = .01

is the same as

bid ask
23.25 23.26 spread = .01

unless I did the math wrong, everything seems the same to me. So how does this make things any different?

 

how about good ole

23 1/4 x1 /2

or 23 1/4 x 3/8

or worst case
23 1/4 x 5/16

never seen 13/50 before

 

ya, me neither....

 

all im trying to say here is that fractions have equivlant decimal numbers.

 

And what others are trying to tell you is that none of the instruments traded in 1/50 or other "weird" fractions.

Trading is/was done in 1/4, 1/8 and etc. and 1/4 is 0.25, which is far from 0.01.
