What is Trading & Securities?
Trading & Securities technology encompasses all systems that power the buying and selling of financial instruments — equities, derivatives (futures & options), bonds, mutual funds, and commodities. India's capital markets are among the world's most sophisticated: NSE is the world's largest derivatives exchange by contracts traded, Zerodha runs entirely on custom-built technology and processes millions of orders daily, and SEBI's T+1 settlement (world's fastest) was delivered entirely through technology transformation. The stack covers order management systems (OMS), exchange matching engines, clearing and settlement via NSCCL/ICCL, depository systems (NSDL/CDSL), and market data infrastructure.
