Introduction
Stock trading looks simple from the outside. Pick a ticker, pick a direction, click buy. The reason most new traders lose money isn’t that the game is complex - it’s that they play it without a plan, without size discipline, and without a way to learn from their own trades.
This guide fixes that. It covers what a stock actually is, how orders work, how to read charts, how to size, how to manage risk, and how to build the habits that keep you in the game long enough to compound. Treat it like a manual, not a blog post.
What Is a Stock?
A stock is fractional ownership in a company. When you buy a share of AAPL, you own a sliver of Apple - entitled to a share of its earnings (via dividends or buybacks) and a vote in corporate matters.
Key concepts
- Share price
- What one share costs on the open market right now.
- Market cap
- Share price × total shares outstanding. The total equity value of the company.
- Ticker / symbol
- The short code a stock trades under (AAPL, MSFT, NVDA).
- Exchange
- Where the stock is listed (NYSE, NASDAQ). The exchange sets listing rules and hours.
- Bid / Ask
- Bid = highest buyer price. Ask = lowest seller price. The gap is the spread.
- Dividend
- A cash payment from the company to shareholders, usually quarterly.
Stock price moves because buyers and sellers disagree on what the company is worth. That disagreement is driven by earnings, news, macro conditions, and sentiment - in roughly that order on any given day.
Accounts & Broker Basics
Cash vs margin account
- Cash account
- You can only trade with settled funds. No Pattern Day Trader rule, but settlement is T+1/T+2 so capital rotates slower.
- Margin account
- You can trade with borrowed money (leverage). Subject to the PDT rule if under $25K: max 3 day trades per 5 business days.
Taxable vs retirement
- Taxable brokerage: flexible, but every realized gain is taxable.
- Roth IRA / traditional IRA: tax-advantaged, but limited annual contributions and withdrawal rules.
- 401(k) / equivalents: usually tied to your employer; limited investment choices but tax-deferred.
Order Types
Order type is the difference between filling at a good price and getting steamrolled. Know these cold.
- Market order
- Fills immediately at whatever the next available price is. Fast but can slip badly on low-liquidity names.
- Limit order
- Fills only at your stated price or better. Default for every entry - you’re never surprised by fill price.
- Stop (stop-market)
- Triggers a market order once price crosses a level. Used to cap losses, but can slip on a gap.
- Stop-limit
- Triggers a limit order at a level. Protects against slip, but may not fill in a fast move.
- Trailing stop
- A stop that moves with price in your favor - locks in gains as the trade runs.
- GTC / DAY
- Time-in-force. GTC = Good Till Cancelled. DAY = expires at market close.
Technical Analysis
Technical analysis is reading the chart - what price has done and what that suggests about what it might do next. You don’t need 40 indicators; you need three clean concepts.
The essentials
- Support & resistance
- Horizontal levels where price has repeatedly reversed. These are your entry and exit anchors.
- Trendlines
- Diagonal structure. Trading with the trend works more often than fading it.
- Moving averages (MAs)
- 20-day, 50-day, 200-day. Act as dynamic support/resistance and filter trend direction.
- Volume
- Confirmation. A breakout on heavy volume is real; on thin volume it’s probably a trap.
- Chart patterns
- Bull flag, cup-and-handle, double top/bottom, head-and-shoulders. Recurring shapes that tilt probability.
- Multi-timeframe
- Confirm the trade on a higher timeframe before executing on a lower one.
Fundamentals in 10 Minutes
You don’t need a CFA to swing-trade stocks. You do need to know what the company does and whether the numbers are improving.
The 5-minute checklist
- 1What does it do?One sentence. If you can’t explain the business, don’t trade the stock.
- 2Is revenue growing?Last 4–8 quarters. Accelerating growth is better than decelerating.
- 3Is it profitable?Or clearly on a path to it. Persistent losses require external funding, which dilutes shareholders.
- 4Valuation sanity checkP/E, P/S, forward P/E vs sector averages. Extreme premiums need extreme growth to justify them.
- 5Cash flow & balance sheetCan they survive 18–24 months without raising? If not, size smaller.
Account Management
Sizing decides whether you survive. Reading charts decides whether you grow. In that order.
Position sizing (hard rules)
- 1–2% max risk per trade for new traders. Cap at 3% if you’re experienced and sizing down.
- Risk = position size × stop distance. Use the Position Sizer in Calculator to derive share count.
- Total open risk: sum of the stops on every open position. Keep this under 6% of account.
- Never average down into a losing position without a mechanical plan that predates the entry.
Profit-taking
Have an exit plan before the order goes in. Three tranches works well:
- Trim one-third at the first target (typically 1R–2R).
- Trim another third at the second target and move stop to breakeven.
- Let the last third run with a trailing stop.
Strength of a Trade
Before you enter, grade the trade. If it fails on two of these, pass. Cash is a position.
- 1Price actionIs the stock trending cleanly, reversing at a known level, or chopping? Chop kills short-term trades.
- 2CatalystWhat’s moving the stock right now? Earnings, macro, sector rotation, news. No catalyst, no conviction.
- 3Technical confirmationA clear level + pattern + volume aligned on at least two timeframes.
- 4Risk-to-rewardMinimum 2:1. Under 2:1, you need to be right more than half the time just to break even after fees.
Trading Psychology
Psychology is the whole game. Trading is doing nothing 90% of the time and waiting for the right pitch - and doing nothing is hard.
Core rules
- Treat trading as a business, not a slot machine.
- Trade the plan. No plan, no trade.
- Journal every trade - setup, rules followed, emotional state, reflection.
- Take profits. Paper gains aren’t real.
- Accept losses. A loss you followed the rules on isn’t a mistake.
- No revenge trades. After two losses in a day, close the platform.
- Sleep, exercise, boredom tolerance - all edges.
Growing a Small Account
A small account grows by not blowing up first. Aggressive sizing on a $3K account is a gambling habit with extra steps.
The phased path
- Phase 1 - under $10K
- Risk 1% per trade. Focus on process and journal quality, not profit. Target: 50 trades logged with clean entries and exits.
- Phase 2 - $10–25K
- Risk up to 2%. Stick to a handful of tickers you know deeply. Max 3 open positions at once.
- Phase 3 - $25K+
- PDT lifts (if margin). Start adding structure: 2–3 repeatable setups, documented in Playbooks, graded by the app.
Cash vs margin under $25K
The PDT rule limits margin accounts under $25K to 3 day trades per rolling 5 business days. A cash account avoids this but settles T+1/T+2. Either is fine - pick one and learn its constraints instead of flipping between them.
Trading With a Full-Time Job
You don’t need to day trade. Most full-time employees would do better to avoid it entirely.
Swing over day
- Multi-day holds let you plan once and manage with alerts.
- You don’t need to be at the screen for entries - use limit orders with conditional triggers.
- 30 min of pre-market prep plus 20 min evening review is enough for 2–3 high-quality swings a week.
Pre-trade checklist
- 1LevelIdentify the level. Price at the level, or mid-range?
- 2CatalystWhat pushes price through? No catalyst, no entry.
- 3SizeRun the position sizer. Don’t eyeball it.
- 4Exit planStop, first target, second target. Written down before the order goes in.
Swing vs Day Trading
Pick one. The setups, mindset, and required screen time are genuinely different - and trying to do both badly is the fastest way to give back gains.
- Day trading
- Intraday only. Close every position by the end of the session. High screen time, high decision frequency, fee and tax drag.
- Swing trading
- Hold hours to weeks. Lower frequency, lower stress, better tax treatment on winning positions held > 1 year. Best for most people with a job.
- Position trading
- Weeks to months. Closer to investing than trading. Works well with a fundamental thesis + technical entry.
Short Selling
Shorting is selling a stock you don’t own (borrowed from the broker) hoping to buy it back cheaper. The mechanics are different enough to treat it as its own skill.
Why it’s harder
- Asymmetric risk. Longs can lose 100%. Shorts can lose more than 100% on a gap or squeeze.
- Borrow cost. Hard-to-borrow names charge daily interest. Check before shorting.
- Short squeezes. Rapid forced covering drives price up fast. If you’re caught, cut fast.
- Market drift. Indices drift up over time; shorts fight this tailwind.
Rules
- Halve your size relative to a long position.
- Use hard stops. No exceptions.
- Avoid shorting stocks under $5, low float, or with obvious squeeze setups unless you deeply understand the dynamics.
Dividends & Corporate Actions
Corporate actions change the price or the quantity of your shares. They show up as surprises if you’re not paying attention.
- Dividend
- A cash payment. Ex-dividend date is when the stock price drops by the dividend amount - you need to own it before that date to get the payout.
- Stock split
- 1 share becomes N shares; price divides by N. Total value unchanged. Often signals confidence from the company.
- Reverse split
- Opposite. Often a warning sign - companies use it to stay above listing price minimums.
- Spin-off
- Company separates a division into its own stock. You receive shares of the new entity proportionally.
- Buyback
- Company repurchases its own shares. Reduces share count, supports price. Usually bullish in moderation.
- Merger / acquisition
- Target usually pops to the offer price. Arbitrage spreads open. Failure of the deal is the tail risk.
Taxes
- Short-term capital gains (held < 1 year): taxed as ordinary income.
- Long-term capital gains (held ≥ 1 year): lower rate - often materially so.
- Wash-sale rule: you can’t claim a loss on a security if you buy a “substantially identical” security within 30 days.
- Capital losses: up to $3,000 per year offsets ordinary income; the rest carries forward.
- Dividends: qualified dividends get the long-term rate; ordinary dividends are taxed as income.
- Set aside 20–35% of realized profits in a separate account for taxes. Automatically.
