At each side of bid/offer spread

[slavN]

Подскажите, пожалуйста, как переводится "At each side of bid/offer spread". Контекст следующий:

A working defi nition is that a market is liquid if participants
can quickly execute (large-volume) transactions at
low costs with minimal impact on market prices.
To do this it will be necessary to have a sufficient
number of participants with sufficient volumes at
each side of the bid/offer spread. In reality, however,
it will also require accurate, reliable and timely price
discovery

Большое спасибо!
