Essential Trading Terms (A–Z) — Smart Glossary for Beginners 2025
Why Learn Essential Trading Terms?
Markets speak their own language. Without a working knowledge of trading vocabulary, beginners waste time guessing what commentators and chart annotations mean. Learning a compact, practical set of essential trading terms reduces confusion, speeds up skill acquisition, and helps you make confident decisions when reading charts, placing orders, or following market news.
Below you’ll find A–Z definitions plus short examples and how each term is used in real trading — not academic textbook lines. Use this as your daily reference and bookmark it for quick review before placing trades.
A–C: Foundation Terms
A — Arbitrage, Ask Price, Asset Allocation
Arbitrage: Buying in one market and selling in another to profit from price differences. Example: small spreads between NSE and BSE are exploited by algorithmic traders for low-risk arbitrage.

Asset Allocation: Dividing capital among asset classes (equities, bonds, commodities) to manage long-term risk and return.

Bear Market: A prolonged downtrend often defined by a 20% decline; market sentiment turns risk-averse.
Breakout: Price moves above resistance (or below support) on increased volume — a potential trend start if confirmed.
C — Call Option, Candlestick, Circuit Limit
Call Option: A derivative giving the right to buy the underlying at a set strike price before expiry. Buyers pay premium; sellers receive it.
Candlestick: A price-bar showing open, high, low, close for the period. Patterns like pin bars, engulfing candles are used for entries.
