The Nordic Exchange to implement circuit breakers and trading safeguards on
June 2nd, 2008 
OMX Nordic Exchanges in Helsinki, Iceland, Stockholm and Copenhagen have
decided to adopt circuit breakers (volatility interrupters) to reduce
uncertainty during volatile periods. In addition, trading safeguards to avoid
erroneous orders will be introduced. The set-up of circuit breakers and trading
safeguards is based on the results of a customer consultation carried out in
H2, 2006. 

Circuit breakers will be implemented on the following instruments: equities
(including First North) and investment funds/ETFs. 

Definition of circuit breakers: Circuit breakers interrupt matching (for up to
4 minutes) when the price movements in a security become relatively large. The
purpose is usually to give the market participants a few minutes to evaluate
any new information, reconsider their interests or remove any erroneous orders.
Circuit breakers have two types of reference prices: a static price and a
dynamic price range. When a circuit breaker is triggered continuous trading is
interrupted by a brief call auction. 

Definition of trading safeguards: Trading safeguards are to be used
simultaneously with Circuit breakers. A trading safeguard rejects orders that
deviate significantly from last traded price. Compared to circuit breakers the
price range for the safeguards will be wider and the purpose of the safeguards
is primarily to avoid erroneous order entries. 

Thresholds that are going to be used for circuit breakers and trading
safeguards: 

Dynamic circuit breakers

+/- 2% for blue chips (OMXC20, OMXH25, OMXS30) 
+/- 3% for blue chips (OMXI15)
+/- 5% for Investment funds/ETF and other collective investment funds
+/- 5% for other shares and First North  + International shares for OMXS 
+/- 10% for penny shares and Illiquid shares 

The reference price that is used in dynamic circuit breakers is the last paid
price 
The dynamic price range will never be less than 0,05 EUR/SEK/DKK/ISK (5 ticks)
Penny shares are defined as shares traded at a price below 5 DKK/SEK/ISK or
below 0,50 EUR 

Illiquid shares will be defined as shares that are in Liquidity Group C*



Static circuit breakers

+/- 10% for blue chips (OMXC20, OMXH25, OMXS30) and all investment funds/ETF
+/- 15% for other shares, First North + International shares for OMXS
+/- 20% for penny shares and Illiquid shares 

The reference price that is used in static circuit breakers is the equilibrium
price from the previous call auction 
Static circuit breakers will not be implemented on Iceland
The static price range will never be less than 0,05 EUR/SEK/DKK (5 ticks)
Penny shares are defined as shares traded at a price below 5 DKK/SEK or below
0,50 EUR 
Illiquid shares will be defined as shares that are in Liquidity Group C*

OMX Nordic Exchanges' trading surveillance reserves all rights to change the
thresholds at any time during the trading. Change of thresholds will be done
only if the market situation requires and a message will be sent to market
participants. 

Trading safeguards

The standard price range for trading safeguards will be set to +/- 15% 
For Penny shares and Illiquid shares the price range will be set to +/- 50%
Penny shares are defined as shares traded at a price below 5 DKK/SEK/ISK or
below 0,50 EUR 
The reference price that is used in trading safeguards is the last paid price
Illiquid shares will be defined as shares that are in Liquidity Group C* 
Trading Safeguards are not applied to warrants. Trading safeguards that have
been used for warrants on OMX Nordic Exchange Helsinki will be abolished as of
June 2, 2008. 
Overnight orders outside previous day's closing are not deleted prior to the
pre-trade phase in the morning 

The circuit breakers and trading safeguards functionality on the Helsinki,
Iceland, Copenhagen and Stockholm markets will be implemented in conjunction
with the next SAXESS release, scheduled for June 2nd, 2008
