Peter Fredricksson, The Trading Mesh, Speed Dating by Candlelight – The Growth of Twilight Pools, here.
With today’s fragmented markets, firms are faced with an increasingly wide choice of trading venues on which they can execute their business. The majority of these fall into one of two categories; either lit markets or so-called dark pools of liquidity. However, there is a third way. An increasing number of market operators are now starting to adopt a “twilight pool” approach, where the level of opacity is controlled to match pre-defined conditions.
A twilight pool is a liquidity venue that is essentially dark, but which illuminates certain elements of information regarding market activity for periods at certain times of day or under specific circumstances, generally for the purpose of attracting more liquidity at those times and matching buyers and sellers. Think of it as speed dating for market participants, but only under semi-lit conditions.
