// Occasionally bid and ask values of 9999.99 and 9999.98 are sent on these feeds. These represent
// the ‘at best’ and ‘at open’ orders respectively. This bid and ask information comes from Euronext for
// Paris and Brussels stocks when there is an 'At Best' or an 'At Opening' order placed on the order book,
// usually during the pre-market phase. The exchange sends these orders to us, not as numerical values,
// but as 'MX' or 'OUV' respectively. The bid and ask fields can transmit numerical data only, consequently
// the letters 'MX' or 'OUV' must be represented in a new numerical format. When a bid or ask is received
// which is 'At Best' (MX), a price value of 9999.99 is transmitted to indicate this state. To represent an 'At
// Opening' (OUV) order, a bid or ask of the value 9999.98 is transmitted. Additionally, an “invalidated price”
// will return a value of 9999.97. Customers are advised to adapt their displays at their discretion to portray
// these states to end users.
