English to Russian Bus/Financial Finance (general) placing limit orders on one side of the market

Здравствуйте.
Прошу помощи в переводе предложения.
A customer engages in a frequent pattern of placing multiple limit orders on one side of the market at various price levels followed by the customer entering orders on the opposite side of the market that are executed and the customer cancelling the original limit orders (activity indicative of “layering").

Как перевести one side of the market и the opposite side of the market.
Впервые сталкиваюсь с такими "наворотами". "Сторона рынка"? Такое вообще может быть?
