01
Slow, data-grounded essays
Every article is built around real numbers — 25 years of NIFTY, four BTC halvings, EPF/PPF math — not opinions dressed as analysis.
Educational · Not investment advice

FAQ
Common questions
Is everything really free?
Yes. No login, no paywall. The site is funded by Google AdSense — you'll see a small number of ads, never invasive ones.
Do you give buy / sell signals or stock tips?
Never. We publish educational essays, math-grounded calculators, and an open-source backtester so you can learn how markets and trading signals actually work.
Are you SEBI / SEC / FCA registered?
No. Epicenter Exchange is an educational platform, not a registered investment adviser, broker, or research analyst. Nothing on the site is investment advice.
Can I use the backtester for real trading?
No. The backtester is for learning how a signal is computed, not for live trading. Real markets add slippage, taxes, latency, and emotional pressure. Past results never guarantee future returns.
Where does the data come from?
Server-proxied Yahoo Finance for indices/stocks, CryptoCompare for crypto historical, CoinGecko for crypto spot. Refreshes roughly every 60 seconds.
