Breadth

Market Breadth

What breadth is: how many NSE stocks participate in a move — and why narrow rallies deserve scepticism. Includes how Streetwhacks measures it and its limitations.

Derivatives

Open Interest

What OI measures in NSE futures and options: outstanding positions, OI change alongside price, and why OI reflects hedging as well as direction.

Sentiment

Put-Call Ratio

What PCR is: put OI or volume divided by call OI or volume. Typical interpretation ranges, why extremes show crowding — and why PCR is never a standalone signal.

Activity

Volume Spikes

What a volume spike is: traded volume versus a symbol's own baseline. How Streetwhacks flags spikes and how they relate to breakouts, news and traps.

Trend

Directional Trends

What directional trend measurement is: bullish vs bearish alignment of price, momentum and volume — and how ranked watchlists are produced.

Rotation

Sector Rotation

What sector rotation is: money moving between NSE sectors (banking, IT, pharma, FMCG, auto, power). How Streetwhacks maps it and what rotation cannot tell you.
