Basics Of Trading
Markets, orders, spreads, and plans—the foundation before strategy.
Overview
Trading basics cover market structure, order types, costs, sessions, and the psychology of following a plan. Without vocabulary and execution awareness, advanced patterns become dangerous decoration.
Bid and ask define where you can sell and buy right now; spread is the cost of immediacy. Market orders prioritize speed; limit orders prioritize price; stop orders trigger action when price reaches a level—each with tradeoffs beginners must feel in paper accounts.
Basics also mean accepting losses as data, sizing positions so emotions stay manageable, and knowing when not to trade—half the skill in many professional narratives.
Scenario: First Live Order
A beginner clicks market buy on a volatile small cap at the open. The last price on screen was $12.40; the fill prints $12.67. Spread widened and slippage ate half their planned risk instantly.
They retry with a limit order at $12.45 and wait. Price comes to them eight minutes later. Same direction idea, different execution cost—a lesson simulators often skip.
They journal intended vs actual fill, spread at entry, and emotional state. Basics win before strategy ever enters the chat.
Market Structure and Sessions
Exchanges and ECNs match orders; liquidity varies by time of day. Opens and closes often show wider spreads and faster moves. Know your market’s hours and halts.
Order Types and Costs
Market, limit, stop, stop-limit, and trailing stops each behave differently in gaps and fast markets. Fees, spreads, and borrow costs reduce edge—account for them in education.
Process Before Strategy
Define watchlist, entry, exit, max loss, and max daily loss before clicking. Paper trade until execution feels boring. Boredom suggests readiness more than excitement does.
Common Mistakes to Avoid
- Market ordering illiquid symbols during volatility.
- Trading size too large for emotional tolerance.
- No written plan before entries.
- Ignoring halts, SSR, or short borrow constraints.
- Jumping to complex options before spot execution is solid.
How to Study This Topic
- Paper trade twenty entries recording intended vs actual fill.
- Practice limit vs market orders in sim during open and midday.
- Write a max daily loss rule and enforce it on paper.
- Learn your broker’s order ticket fields one by one.
- Explain bid-ask-spread to a friend without jargon—teaching tests mastery.
Key Takeaways
- Execution quality is a skill separate from direction picking.
- Spreads and slippage are real costs.
- Order type choice matters most in fast markets.
- Written plans reduce impulsive clicks.
- Paper trading should mimic realistic fills.
Learning Tip
Record five paper trades with intended vs actual fill price and spread at entry.
When live-size eventually comes, start small enough that a bad fill teaches without harming your month.
