Co-location-based HFTs, global trading firms lead to 4x jump in share of algo trading in last decade

About this update from Nairobi Securities Exchange Plc

Algorithmic trading now contributes over half of NSE’s cash market volumes and around 40% of BSE's volumes with the share of such trading seeing a four-fold jump in the last decade.Experts attribute this surge to the increased usage of algos by proprietary trading desks, co-location based high frequency traders (HFTs), and global trading firms that possess both the technological infrastructure and capital needed for deploying complex, low-latency strategies.

That was a big trigger. Over the next two years, other brokers followed suit, and suddenly a new segment opened up,” said Trivesh.Referring to the regulatory framework for algos, Khoday says that while the algo consultation has been pending for three years, it is moving now. “They are looking to introduce norms around white-box vs bl...
