The proposed guidance aims to reduce disruptions to fair and orderly Canadian markets. IIROC confirms dealers’ obligations under the UMIR electronic trading rule amendments, which took effect March 1, 2013. These apply the entry of stop-loss orders and the execution of triggered orders.

“Equity trading is becoming [more] automated and complex, [so] it’s important that all participants take responsibility for the integrity of the markets,” says IIROC president and CEO Susan Wolburgh Jenah. “Regulatory intervention by IIROC should be required only in exceptional circumstances.”

IIROC will continue monitoring the impact of stop-loss orders on markets, will assess what additional regulatory steps are required.
