The most important functions of the TCA Aggregates module from an investors’ point of view:

Market Impact indicates how much an order of a given value would have on the short-term change in the price of a given asset. This is the ”liquidity price” paid by the taker. Market impact is calculated each minute for each asset.

Book Depth data is conceptually the opposite of market impact. In market impact, a specific order value is assumed and a spread is obtained. In the case of book depth, a specific spread is assumed and an order value is obtained. This data shows the actual liquidity available to investors at a given spread price.

Volatility measures the share price volatility on the basis of the midpoint price – i.e. the middle price between the best buy and sell bids

Spread Leeway measures the spread between the best quoted buy and sell prices, expressed as the number of tick size minus 1.

Order-to-trade (OTT) meter indicates how many operations on orders occur per 1 trade. A high OTT (amounting to a dozen / several dozen) is sometimes interpreted as an indication of a high level of saturation of trade with orders generated by HFT-type algorithms.

Delay Cost specifies the so-called time risk of a passive investor (maker) placing an order in the order book and waiting for the other party – the active investor (taker) to confirm the order

Probability of fill is calculated as the number of orders fully fulfilled divided by the number of new orders placed in a given time. Only orders placed during a given trading session are analysed (orders from the previous trading session are ignored).
