TMX’s new trading engine leads to more disappearing orders: study

The faster new computers at the Toronto Stock Exchange are leading to more noise in the stock markets caused by orders that disappear, researchers at brokerage firm ITG Canada found in a study.

TMX Group Inc., owner of the TSX, rolled out the new “Quantum XA” trading computers in stages earlier this month, enabling ITG to look at the week of June 9th to June 13th, when about half the stocks on the TSX were being traded on the older, slower system and half on the much faster new system.
