Key Terms in Trading
Key Terms In Trading
Learning to trade can feel like learning a new language. From "pips" to "leverage," the terminology may seem overwhelming at first. But understanding these key terms is essential for beginners. Knowing them helps you follow the markets, place trades effectively, and manage your risk confidently. Think of this as your trading dictionary — a foundation for smarter decisions.
Basic Market Terms
Buy (Long)
Buying, or going "long," means purchasing an asset because you believe its price will rise over time. You profit by buying low and selling high.
Example:
- You buy 10 shares of a stock at $50 each.
- Initial investment: 10 × $50 = $500
- Later, the stock rises to $60 per share. You sell all 10 shares: 10 × $60 = $600
- Profit: $600 − $500 = $100
- Percentage gain: ($100 ÷ $500) × 100 = 20%
- So your $500 grew by 20%, thanks to a well-timed purchase.
Sell (Short)
Shorting means selling an asset you don't own because you expect its price to fall. You borrow the asset, sell it, then buy it back later at a lower price. The difference is your profit.
Example:
- You short 10 shares at $80 each:
- Money received = 10 × $80 = $800
- Price drops to $60 → buy back 10 shares = 10 × $60 = $600
- Profit: $800 − $600 = $200
Note: Shorting carries higher risk because if the price rises instead of falling, losses can be significant.
Bid & Ask
Every asset has a bid and ask price:
- Bid: Highest price someone is willing to buy at
- Ask: Lowest price someone is willing to sell at
Example:
- Quote shows Bid = $100 / Ask = $100.05
- If you buy immediately, you pay $100.05
- If you sell immediately, you receive $100
- The small difference between these two is called the spread, and it represents one of the costs of trading.
Spread
The spread is the difference between the bid and ask prices. It's a tiny built-in cost of entering a trade.
Example:
- Bid = $100, Ask = $100.05
- Spread = $0.05
- Buying 100 shares at the ask and selling at the bid → immediate cost = 100 × $0.05 = $5
Tip: Spreads are usually tighter in liquid markets and widen in volatile or thinly traded markets. Beginners should watch spreads, as a wider spread increases the cost to enter and exit trades.
Orders & Execution
Market Order
A market order instructs the broker to buy or sell immediately at the best available price. It guarantees speed but not the exact price, as prices can move quickly (slippage).
Example:
- You buy 10 shares of a stock at $50 each.
- Quote: Bid = $100, Ask = $100.05
- Market buy for 100 shares → cost = $10,005
- If sold immediately at $100 → proceeds = $10,000
- Immediate difference due to spread: $5 loss
- Slippage: If momentum moves fast and your buy fills at $100.20 → extra $15 cost.
Limit Order
A limit order lets you choose the price at which you want to buy or sell.
- Buy limit: Below current market price
- Sell limit: Above current market price
Example:
- Market price = $100
- Buy limit at $98 for 100 shares → executes only if price drops to $98
- Partial fill: 40 shares execute → 60 shares remain open
- Limit orders give control over price but may not execute immediately.
Stop-Loss (Stop Order)
A stop-loss is a safety net that automatically closes a trade if the price moves against you. It protects your capital and prevents catastrophic losses.
Example:
- Buy 100 shares at $50
- Stop-loss at $45
- If price falls to $44.50, the trade closes → loss = $550 (11%)
Tip: Stop-limit orders can avoid selling below a set price but may fail to execute in a fast-moving market.
Take-Profit
Take-profit automatically closes a trade once it hits your target price, locking in gains.
Example:
- Buy 100 shares at $50
- Take-profit at $60 → proceeds = $6,000 → profit = $1,000 (20%)
Pro tip: Most traders use OCO orders (One Cancels the Other) to combine stop-loss and take-profit on the same trade.
Money & Risk
Leverage
Leverage allows you to control a larger position with a smaller deposit. It amplifies both profits and losses.
Example:
- Account balance = $1,000
- Leverage 1:100 → control $100,000 worth of trades
- 100 pip gain = ~$1,000 profit → doubles your account
- 100 pip loss = ~$1,000 → entire account wiped
Tip: Beginners should start with low leverage (1:10 or less) to reduce risk.
Margin
Margin is the deposit required to maintain a leveraged trade.
Example:
- Trade size = $100,000
- Leverage 1:100 → margin = $1,000
- If account balance falls below required margin, trades may be automatically closed (margin call).
Lot
A lot is the standard unit size of a trade:
- Standard Lot: 100,000 units
- Mini Lot: 10,000 units
- Micro Lot: 1,000 units
Example: 1 pip movement in EUR/USD:
- Standard Lot → $10 profit/loss
- Mini Lot → $1
- Micro Lot → $0.10
Pip
The smallest unit of price movement in forex:
- Most pairs → 0.0001
- JPY pairs → 0.01
Example:
- EUR/USD moves from 1.2000 → 1.2005 = 5 pips
- 1 standard lot → profit/loss = 5 × $10 = $50
Risk-to-Reward Ratio (R:R)
Compares potential profit vs. potential loss.
Example:
- Buy EUR/USD at 1.2000
- Stop-loss = 1.1950 (50 pips risk)
- Take-profit = 1.2100 (100 pips reward)
- R:R = 1:2 → risk $1 to potentially gain $2
Trading Strategies & Styles
Scalping
Quick trades capturing tiny price moves, repeated multiple times daily. Requires speed, focus, and tight spreads.
Example:
- Buy EUR/USD at 1.2000 → sell at 1.2002 → $20 profit per lot
- Repeat 20–30 times a day
Day Trading
Open and close trades within the same day to capture intraday movements. Avoids overnight risk.
Example:
- Buy gold at $2,500 → sell at $2,550 → profit $50 per contract
Swing Trading
Hold trades for days or weeks to catch medium-term market swings.
Example:
- Buy Apple at $150 → sell at $170 after 2 weeks → profit $2,000
Position Trading
Long-term approach, holding trades for months or years to benefit from major trends.
Example:
- Buy Bitcoin at $10,000 → sell at $60,000 → profit $50,000
Hedging
Opening an offsetting trade to reduce risk in your main position.
Example:
- Buy oil futures at $80 → short oil futures as hedge
- Loss in long position offset by gain in hedge → reduced overall risk
Market Behavior
Liquidity
Ease of buying or selling an asset without affecting its price much.
Example:
- EUR/USD → high liquidity → trade instantly with small spreads
- Thinly traded stock → hard to sell quickly without lowering price
Volatility
How much and how fast prices move.
Example:
- Bitcoin $20,000 → $22,000 in a day → high volatility
- EUR/USD 1.1000 → 1.1010 → low volatility
Bull Market
Sustained period of rising prices, driven by investor confidence.
Example:
- S&P 500 from 700 → 3,000 (2009–2020) → long-term bull market
Bear Market
Sustained period of falling prices, driven by investor fear.
Example:
- 2008 financial crisis → S&P 500 lost over 50%
Support Level
Price point where an asset tends to stop falling due to buying interest.
Example:
- EUR/USD repeatedly bounces at 1.1000 → strong support level
Resistance Level
Price point where an asset tends to stop rising due to selling pressure.
Example:
- Gold rises toward $2,000 multiple times → acts as resistance
