Market Quality Metrics (MQM) is a free service offered by SIX Swiss Exchange. This innovative statistics tool
ensures greater comparability and increased pre-trade transparency as it allows investors to compare
the average spreads of the individual products on a daily basis.
In addition to the average spreads of the best bid and offer prices, the availability of these prices
is also shown. The calculation takes into account both market maker offers and normal client orders.
It also shows what was offered at the innermost level of the order book for an average volume
(quantity and value).
