Lesson 3: Volume Analysis & Trade Execution

Use volume to confirm trends, identify accumulation/distribution, and execute trades with proper entry and exit strategies.

Why Volume Matters

Volume is the number of shares or contracts traded during a given period. It's the fuel that drives price movement — without volume, price changes are unreliable.

Mental model: Price is what you pay; volume is what you get. High volume means conviction; low volume means uncertainty.

Volume基本原则

Volume Level Interpretation What It Means
High volume + price up Strong buying interest Bullish confirmation
High volume + price down Strong selling pressure Bearish confirmation
Low volume + price up Weak rally Likely to reverse
Low volume + price down Weak selling Likely to bounce

Volume Analysis Techniques

1. On-Balance Volume (OBV)

OBV adds volume on up days and subtracts on down days, creating a cumulative indicator.

OBV Signal Price Action Meaning
OBV rising + Price rising Confirmation Trend is strong
OBV rising + Price flat/rising Accumulation Smart money buying
OBV falling + Price flat/falling Distribution Smart money selling
OBV divergence Price up, OBV down Warning — trend may reverse

2. Volume Profile

Volume Profile shows how much volume occurred at each price level, revealing where most trading happened.

Level Type Description Significance
POC (Point of Control) Price with highest volume Strongest support/resistance
Value Area 70% of volume "Fair value" zone
Low Volume Nodes Price with least volume Price moves quickly through these

3. Accumulation/Distribution Line

This indicator measures money flow into and out of a security.

A/D Line Price Interpretation
Rising Rising Healthy uptrend
Rising Falling Divergence — potential reversal up
Falling Rising Divergence — potential reversal down
Falling Falling Healthy downtrend

Building a Complete Trading System

A trading system combines analysis with rules for entry, exit, and risk management.

Entry Rules (Example System)

Condition Requirement
Trend Price above 50-day MA
Momentum RSI between 40-70 (not overbought)
Confirmation MACD bullish crossover
Volume Above-average volume on entry day
Support Price near a support level

Exit Rules

Exit Type Trigger
Stop Loss Price falls 7-8% below entry (or below key support)
Trailing Stop Price closes below 20-day MA
Profit Target Price reaches resistance or RSI > 70
Time Stop No movement after 2-3 weeks

Position Sizing — Protecting Your Capital

The amount you invest in each position should be based on your risk tolerance and account size.

The 1% Rule

Never risk more than 1% of your total portfolio on a single trade.

Portfolio Size Max Risk Per Trade Position Size (with 7% stop)
$10,000 $100 ~$1,428
$50,000 $500 ~$7,142
$100,000 $1,000 ~$14,285

Formula: Position Size = (Account × Risk%) / (Entry Price - Stop Loss Price)

Trade Journal — Learning from Every Trade

Keep a record of every trade to improve over time:

Field Purpose
Date/Time When you entered
Stock What you traded
Entry Price What you paid
Stop Loss Your risk level
Target Your profit goal
Reason Why you took the trade
Result P/L and lesson learned

Common Mistakes to Avoid

  • Mistake: Ignoring volume on breakouts — Fix: Always confirm breakouts with above-average volume.
  • Mistake: Risking too much per trade — Fix: Follow the 1% rule religiously.
  • Mistake: Having no exit plan — Fix: Define stop loss and target BEFORE entering.
  • Mistake: Averaging down on losers — Fix: Cut losses short; let winners run.

Professional Tips & Tricks

  • Volume precedes price — watch for volume spikes before big moves.
  • Keep a trading journal; it's the fastest way to improve.
  • Risk management is more important than stock selection.
  • paper trade (simulate) your system before using real money.

Key Takeaways

  • Volume confirms trends — price moves without volume are unreliable.
  • OBV and Volume Profile reveal accumulation and distribution patterns.
  • A complete trading system includes entry rules, exit rules, and position sizing.
  • The 1% rule protects your capital from catastrophic losses.
  • Keep a trade journal to continuously improve your performance.

## Volume Interpretation Guide

| Volume | Price | Signal | Action |
|--------|-------|--------|--------|
| High | ↑ Up | Strong Buy | Confirm entry |
| High | ↓ Down | Strong Sell | Exit/Short |
| Low | ↑ Up | Weak Rally | Wait/Be cautious |
| Low | ↓ Down | Weak Sell | Potential bounce |

Risk Per Share: $_______

Position Size = Risk Amount ÷ Risk Per Share
= $_______ ÷ $_______
= _______ shares

## Complete System Checklist

Before EVERY trade, check:
□ Trend confirmed (50 MA direction)
□ Momentum aligned (RSI 40-70)
□ Volume confirms (above average)
□ Near support/resistance
□ Risk defined (stop loss set)
□ Position sized (≤1% risk)
□ Exit plan ready (target + stop)

Code Visualization Tips

  • Compare volume bars during rallies vs. pullbacks — rallies on high volume are healthy.
  • Draw horizontal lines at high-volume price levels — they become future support/resistance.
  • Watch for volume spikes before earnings or major news — they signal institutional activity.

Professional Tips & Tricks

  • Volume precedes price — unusual volume often signals upcoming moves.
  • Paper trade your system for at least 3 months before risking real money.
  • The best traders lose on 40-50% of trades but make money through position sizing.
