Basic Market Terms

Term	Meaning
Bull Market	A market phase characterised by rising prices and general investor optimism.
Bear Market	A phase marked by falling prices, typically defined as a 20% or greater decline from recent highs.

2. Order Types

Choosing the correct order type affects execution price, speed, and risk control.

Order Type	What It Does	Best Used When
Market Order	Executes immediately at the best available prevailing price.	You prioritise execution speed over exact price precision.
Limit Order	Executes only at a specified price or better.	You want strict price control and can wait for the market to reach your level.
Stop-Loss Order	Triggers a market sale once price drops to a designated threshold.	You want to cap potential downside risk on an open position.
Stop-Limit Order	Combines a stop trigger price with a limit price condition.	You want automated loss protection bundled with price boundaries.
GTT (Good Till Triggered)	Allows you to set a trigger price and limit price in advance. When the trigger price is reached, the limit order is sent to the exchange for execution.	You want to place a buy or sell order at a predefined price without having to monitor the market continuously.

Important Mechanics:

Bid-Ask Spread: The gap between the highest price a buyer is willing to pay (bid) and the lowest price a seller will accept (ask). Narrower spreads indicate higher liquidity.

Volume: The total number of shares traded during a specific interval, used alongside price action to validate trend strength.

3. Trading Position Terms & Styles

Long Position: Buying security with the expectation that its price will appreciate.

Short Position / Short Selling: Borrowing and selling shares at current market prices with the intent of repurchasing them later at a lower price to pocket the difference.

Square Off: The act of closing out an open intraday trading position.

Holding Period: The calendar duration between purchasing and liquidating an asset.

Resistance	A price ceiling where upward momentum tends to stall due to selling pressure.
Moving Average (MA)	The rolling average price over a set lookback period, smoothing out short-term noise.
Volume	The aggregate share turnover, indicating the underlying conviction of a price move.
RSI (Relative Strength Index)	A momentum oscillator measuring the speed and change of price movements on a 0–100 scale.

Formula for Simple Moving Average (SMA): SMA = (Sum of Closing Prices over N periods) ÷ N

5. Derivatives & Leverage Terms

Term	Meaning
F&O (Futures & Options)	Contracts whose value derives from an underlying asset, such as an index or equity.
Margin	Upfront collateral required by a broker to open and maintain a leveraged position.
Leverage	Utilising borrowed capital to multiply market exposure, which magnifies both gains and losses.
Lot Size	The standard pre-determined number of units comprising a single derivative contract.
Mark-to-Market (MTM)	Daily accounting settlement reflects profits or losses on open derivative positions.

Capital Loss Set-Off	Regulatory provision allowing capital losses to offset capital gains.	Reduces overall tax liability subject to carry-forward rules under the Income Tax Act.

Golden Rules for Beginners

Establish an Emergency Fund: Keep 3 to 6 months of living expenses in secure, liquid savings before risking capital in equities.

Clear High-Interest Debt: Unsecured credit card debt compounds much faster than average market returns; clear liabilities first.

Avoid Concentrated Speculation: Never risk capital you cannot afford to lose on low-cap, unverified tips or speculative derivative plays.

Mastering terms like limit orders, margin requirements, and regulatory frameworks build a strong foundation for independent decision-making. Continuous learning and adherence to risk controls remain your best safeguards in the financial markets.
