Why is order book essential?

Short-term and mid-term strategies are appreciated for higher returns and faster strategy validation compared to long-term trading. For those strategies, you need detailed market microstructure data including individual trades and order book.

Order book data are needed for precise backtests, execution simulation, (statistical) arbitrage strategies or market making. Knowing the best price levels or available liquidity allows you to precisely determine for which prices are you able to trade, what liquidity is available in the order book or how much slippage will occur on trade. In the end, you are able to conduct precise backtests, that will closely match real execution.
