Market microstructure is generally speaking the way markets are organized at the impact of there structure on the price formation process.

Market microstructure for Quants

The Chapter Market Microstructure Knowledge Needed for Controlling an Intra-Day Trading Process of the Handbook on Systemic Risk states:

The market micro-structure of an asset class is a mix of the market design, the trading behaviours of trading agents, the regulatory environment, and the availability of correlated instruments (like Equity Traded Funds, Futures or any kind of derivative products). Formally, the micro-structure of a market can be seen as several sequences of auction mechanisms taking place in parallel, each of them having its specificity.

To optimise his behaviour, a trader has to choose an abstract description of the micro-structure of the markets he will interact with: this will be his model of market micro-structure. It can be a statistical macroscopic one like in the widely used Almgren-Chriss framework, in which the time is sliced in 5 or 10 minutes long time intervals during which the interactions with the market are aggregated in two statistical phenomena: the market impact as a function of the ``participation rate'' of the trader and the volatility as a proxy of the market risk. It can also be a microscopic description of the order-book behaviour like in:

Cost of trading

Questions regarding trading costs, slippage, etc.

Orderbook dynamics

Question about this (and the predictive power of imbalance)

High Frequency Trading (HFT)

Questions about HFT

High frequency / intraday volatility estimate

Questions about this and microstructure noise

There is a large overview of state of the art in microstructure in the talks of the conf held every two years (2010 and 2012 up to now, 2014 is planned) in Dec in Paris Market microstructure: confronting many viewpoints.
