Understand the markets before you risk a rupee.
I build free, structured knowledge bases that teach the mechanics and the risk of trading — options strategies, the option Greeks and technical indicators — with original diagrams and Nifty & Bank Nifty examples. No tips, no calls, no paywall.
The network

What this network stands for
Genuinely free
No paywall, no login, no ads, no "sure-shot calls". Just education, held to a documented standard.
Independent
No affiliation with any broker, adviser or product issuer. Nothing here is a recommendation.
Original diagrams
Every chart and payoff is computed and drawn from scratch — no stock images, no black boxes.
India-first
Examples use Nifty, Bank Nifty, NSE realities and Indian lot sizes — not generic US tickers.
About Bulan Sarkar
I'm Bulan Sarkar. I build these sites because too many people in India trade before they understand what they are trading. The material aimed at retail traders is often too shallow, too jargon-heavy, or thinly disguised marketing for tips. This network is the opposite of that — calm, structured, advertisement-free reference libraries that teach the theory and, above all, the risk, using Indian-market examples.
The goal is not to make you trade more. It is to help you understand the risk you are taking — and sometimes, to help you decide not to take a bad trade. Every site documents how its content is produced, sourced and corrected.
