What is DSViewer?
DSViewer is a historical market data viewer built for exploring and replaying NIFTY 50 options data. Select a trading-day dataset, configure your charts, choose a reference price, and replay the session from any point in time.
Complete data
Every available NIFTY 50 call and put option for a selected trading day.
1-minute replay
Every candle develops second by second, the way it did on the trading floor.
Interactive analysis
Multiple charts, timeframes, indicators, and symbol-selection modes at once.
Experience the market, minute by minute
At the default 1× replay speed, the chart updates every second while the current 1-minute candle develops. After 60 seconds, the next candle begins — no jump cuts, no gaps.
See more than one side of the market
DSViewer gives you a multi-chart layout so you can follow the underlying index and its options together — compare movement across charts and timeframes while the replay runs, and layer on indicators like MA, EMA, or VWAP as you go.
