As a result of this connection, Fidessa network’s 2,400 buy-sides and 600 brokers will be able to route orders via Haitong to the Shanghai and Shenzhen stock exchanges.

Since 2008, Haitong Securities has provided access to the Shanghai Stock Exchange via its subsidiary, Shanghai Stock Communication Company (STOCOM).

Fidessa has now passed conformance testing with STOCOM, opening the way for inbound trading via Haitong of A-shares and B-shares in these markets.

Fidessa Asia managing director Jean-Pierre Baron said as international order flow into China continues to grow, and transits for a large part via Hong Kong, Fidessa has seen increased demand to build a pipe between the Hong Kong hub and China.

"By connecting through STOCOM to the Haitong execution services, we have established a bridge that will act as a powerful accelerator for reaching the mainland markets," Baron said.

The Fidessa trading network covers more than 150 markets across EMEA, Asia Pacific and the Americas. The network has more than 3,000 members from both buy-side and sell-side, and carries executed order flow worth more than $800bn every month.
