Is there any data latency in NEST, as compared to NSE NOW? Have heard that NSE NOW is faster in reflecting the data as compared to NEST, as NOW connects directly to NSE servers, where as NEST connects to servers maintained by the brokers.
NOW when originally launched back in 2008/09 was markedly faster than all other platforms. No they don’t directly connect to NSE servers, it still has its own OMS/RMS in a separate data center as compared to NSE’s trading servers. It was faster because NSE had built a huge capacity for NOW, and there were only a few users on it.
Over the last few years, the number of users of NOW went up significantly, the performance in terms of speed of ticks has come down to other platforms level.
Btw, NEST and NOW were built by the same team (Omnesys), so everything else on NOW has always been the same.
