It won't work I suppose, or Am I missing something. Please clarify more.
The links describe the RTD links of their softwares like X-Trader.
NSE NOW and NEST also have RTD links but they only give best bid/ best ask via RTD link (although snap quote shows top 5 bid/asks). But even these top 5 cannot be accessed by RTD links.
NSE is giving market depth upto top 20 bids and top 20 asks but I don't know of any retail data feed that is offering that to individual traders.
