What Does Price Tell You?
The Essence of Price Moves: Supply vs. Demand
Simply put:- More people want to buy → demand exceeds supply → prices rise
- More people want to sell → supply exceeds demand → prices fall
Candlestick Charts: The Battle Report of Bulls vs. Bears
Each candlestick records the outcome of the bull–bear fight over a period of time: Four key pieces of information in a candlestick:- Open: the price at the start of the battle
- Close: the price at the end of the battle
- High: bulls’ strongest point of attack
- Low: bears’ strongest point of attack
- Large bullish candle (red): bulls dominate; strong buying
- Large bearish candle (green): bears dominate; heavy selling
- Long upper wick: bulls were strong, but got pushed back by bears
- Long lower wick: bears were strong, but got counterattacked by bulls
Volume: Confirming the Reliability of Price Moves
Key principle: price signals are only reliable when confirmed by volume. Four price–volume scenarios:- Price up, volume up → healthy uptrend, sustainable ✅
- Price up, volume down → weakening momentum, watch risk ⚠️
- Price down, volume up → downtrend confirmed, avoid bottom-fishing ❌
- Price down, volume down → declining momentum fades, may be bottoming ⚠️
- If price makes a new high but volume shrinks, it suggests insufficient buying, and the rally may not be sustainable
- If price drops sharply but volume is small, it suggests limited selling pressure and may be a technical pullback
Identifying Buy and Sell Timing
Three Characteristics of a Technical Bottom
1. Price–Volume Divergence
Phenomenon: price keeps falling, but volume contracts明显 Meaning: selling pressure dries up; bearish strength weakens Example: after consecutive declines, a big down day occurs with volume less than half the average2. Oversold Rebound Signal
Phenomenon: price falls too much in a short time and moves far away from moving averages Meaning: the decline is too fast; a technical rebound may be imminent Quantitative standard: price drops more than 15% below the 20-day moving average3. Support Confirmation
Phenomenon: price finds support multiple times at a certain level Meaning: strong buying support exists at that level How to identify: historical lows, round-number levels, key moving averages How Openstrat identifies technical bottoms:- Analyze multiple timeframes simultaneously (daily, hourly, minute)
- Combine signals from multiple technical indicators
- Compute the probability of bottom formation (50%–100%)
Warning Signs of a Technical Top
1. Price Down with Volume Up
Phenomenon: price falls while volume expands Meaning: profit-taking and panic selling surge at the same time Response: reduce positions or stop out immediately2. Breakdown to the Downside
Phenomenon: breaks below a key support level (e.g., the 20-day moving average) Meaning: the bulls’ defense line is breached; the trend may reverse Confirmation standard: closes below support for two consecutive days3. Heavy Resistance
Phenomenon: price repeatedly rallies and pulls back, unable to break a certain level Meaning: strong selling pressure at that level; limited upside Practical takeaway: don’t fantasize about a breakout—take profits in timeThe Power of Trend: Trade with the Trend
A simple way to judge trends:- Uptrend: successive highs are higher, and lows are higher
- Downtrend: successive highs are lower, and lows are lower
- Sideways consolidation: highs and lows fluctuate within a range
- Don’t trade against a trend once it’s established
- Early trend stages are the best entry opportunities
- Prepare to exit near the end of a trend
Common Traps and Misconceptions
1. The “Catching the Bottom” Trap: The Knife Is Still Falling
Wrong idea: the stock has fallen a lot, so it must be cheap—time to catch the bottom. Reality:- In a downtrend, every time you think it’s “cheap enough,” it can keep falling
- There is no lowest—only lower
- Catching the bottom halfway down the mountain is the norm
- Wait for confirmation that the decline has stabilized before considering entry
- Scale in—don’t buy all at once
- Set a stop-loss to control downside risk
2. Chasing Highs and Selling Lows: The Classic Retail Mistake
The psychology behind chasing highs and selling lows:- See a big surge → fear missing out → buy at the top
- Price drops after buying → psychological pressure rises → hope for a rebound
- It keeps dropping → panic erupts → sell at the bottom
- Herd mentality: seeing others profit triggers copycat behavior
- Loss aversion: fantasize during small losses; despair and capitulate during big losses
- Confirmation bias: only pay attention to information that supports your view
- Make a buying plan—don’t trade on impulse
- Set stop-loss levels and execute them strictly
- Focus on technical signals, not just price moves
3. The Boundaries of Technical Analysis: When It Doesn’t Work
When technical analysis fails:Major unexpected events
- Geopolitical conflicts
- Natural disasters
- Sudden policy changes
- Major financial scandals
Extreme market sentiment
- Extreme greed (bubble phase)
- Extreme fear (financial crisis)
- Liquidity droughts
- When major events occur, prioritize risk control
- In extreme conditions, reduce exposure or pause trading
- Wait until sentiment stabilizes before applying technical analysis
Stock-specific special situations
- Trading halts due to restructurings and subsequent resumptions
- Earnings blowups or major upside surprises
- Manipulation by dominant players
- Abnormal volume changes
- Price action severely diverging from the broader market
- Large swings without a clear reason
