// The bet_stop message is an optimized signal to indicate that all, or a set of
// markets should be instantly suspended (continue to display odds, but don't
// accept tickets). The same effect can also be achieved by sending an
// odds_change message that lists all the affected markets and moves them to
// status="-1" (suspended).
// It is important to keep in mind that only active
// markets should be set to suspended, and not markets that are already
// deactivated, settled or cancelled. This is also the case for the attribute
// market_status (explained HERE). If it is not present, the market should be
// moved to suspended. However, if the market is already deactivated, settled or
// cancelled this is not a good practice. Only move ACTIVE markets to suspended.
