In the detailed quote section, offers with equal prices are grouped by the same color. There are five available color groups. The quotes with best prices are placed on the top and regrouped each time a new quote comes.
The detailed quote section is displayed as a table with the following columns:
* MPID (market participant ID) – ECN or exchange, where the orders are set;
* Price – buy or sell price from the highest Bid and the lowest Ask to lower Bids and higher Asks;
* Size – the volume being offered to purchase at a specified Bid price or to Sell at a specified Ask price;
* Time – time of offer;
* Avg. price – the price with slippage that appears because of low liquidity;
* Total size – the aggregated traded volume;
* Order – order number of this current price;
* Contr CCY value – the value of Ask/Bid size recalculated in the quoting currency, Price \* Ask/Bid size;
* Contr CCY Total value – the value of total Ask/Bid size recalculated in the quoting currency, Price \* Total Ask/Bid size.
