Expansion of NYMEX No-Bust Ranges for Crude Oil and Related Products
Effective Sunday, May 11, 2008, NYMEX has announced that the following NYMEX on CME Globex® products will have their no-bust ranges and stop spike logic values expanded from $0.25 to $1.00 for:
Crude Oil (CL) – 100 ticks
Brent Crude (BB) – 100 ticks
Last Day Brent Crude (BZ) – 100 ticks
REBCO Crude (RE) – 100 ticks
miNY WTI Crude (QM) – 40 ticks
Stop Spike Logic helps prevent excessive price movements by introducing a momentary pause in matching ("Reserved State") when triggered stops would cause the market to trade outside predefined values. This momentary trading pause allows new orders to be entered and matched against the triggered stops in an algorithm similar to market opening. Please note that Market Orders submitted during the Reserve State will be rejected. All other order types will be accepted.
