平均真实波幅
Average True Range (absolute value), representing volatility/risk.
TR=max(H−L,|H−Cₚᵣₑᵥ|,|L−Cₚᵣₑᵥ|), ATR=Wilder smoothing(TR,14)
Used for stop-loss (e.g. 2×ATR) and position sizing; does not indicate direction.
布林带
MA as the middle band, standard deviation as the bandwidth.
Mid=MA(C,20), Upper/Lower=Mid±2σ
Narrowing bands (squeeze) signal an impending move; price riding the upper band = strength.
布林带宽
Relative band width, quantifying volatility and squeezes.
BBW=(Upper−Lower)/Mid
Historical lows = squeeze (often precedes a big move); sharp expansion = breakout.
布林带 %B
Price's relative position within the bands (0=lower band, 1=upper band).
%B=(C−Lower)/(Upper−Lower)
>1 breaks above the upper band (overbought), <0 breaks below the lower band (oversold).
蔡金波动率
Uses the rate of change in the high-low spread to measure volatility expansion/contraction.
(EMA(H−L,10)−its value n periods ago)/its value n periods ago×100
A sharp rise = surging volatility (top panic/breakout); a slow decline = settling into calm.
唐奇安通道
A channel formed by recent highs and lows, the core of the Turtle method.
Upper=n-high, Lower=n-low, Mid=(Upper+Lower)/2, n=20
A new n-period high = buy, a new low = sell.

r=ln(C/Cₚᵣₑᵥ), HV=Std(r,n)×√252
Compared with implied volatility (IV) to judge whether options are cheap or expensive.
肯特纳通道
A trend channel with an EMA midline + ATR bandwidth.
Mid=EMA(C,20), Upper/Lower=Mid±2×ATR(10)
Breaking above the upper band = strength; Bollinger Bands contracting inside the KC = squeeze (TTM Squeeze).

σ=√(Σ(Cᵢ−MA)²/n), n=20
Rising σ = increasing volatility and rising risk.

Difference between two EMAs, measuring trend direction, strength and momentum shifts.
DIF=EMA(C,12)−EMA(C,26); DEA=EMA(DIF,9); Histogram=(DIF−DEA)×2 (×2 is the Chinese TongDaXin/THS convention; international platforms StockCharts/TradingView do not multiply by 2, i.e. DIF−DEA)
DIF crossing above DEA = golden cross (buy), crossing below = death cross (sell); new price high while DIF does not = top divergence (bearish).
简单移动平均线
Arithmetic mean of the last n closes, smoothing price and identifying trend direction.
SMA = (C₁+…+Cₙ)/n
Price above the MA is bullish, below is bearish; commonly 5/10/20/60/120/250-day; short MA crossing above long MA = golden cross (buy), crossing below = death cross (sell).
动向指标/平均趋向指数
DMI gauges direction, ADX gauges trend strength (directionless).
+DI=100×EMA(+DM)/ATR, −DI=100×EMA(−DM)/ATR, DX=100×|+DI−−DI|/(+DI+−DI), ADX=EMA(DX,14)

ATR-based trend-following line giving clear long/short and stop-loss levels.
Upper=HL2+m×ATR, Lower=HL2−m×ATR, commonly (10,3)
Price above the line = long (green), below = short (red); a flip is the signal, usable as a trailing stop.

Normalized Gaussian-weighted sum, commonly (9,0.85,6)
Larger offset = more sensitive; crossovers/turns serve as signals.

ER=|net change|/Σ|period-to-period change|, SC=[ER×(2/3−2/31)+2/31]², KAMA=KAMAₚᵣₑᵥ+SC×(C−KAMAₚᵣₑᵥ)
More noise-resistant in choppy markets; crossovers or turns serve as signals.
包络线
A channel set a fixed percentage above and below a MA.

Touching the upper band is overbought, touching the lower band is oversold.
抛物线转向
Stop And Reverse, a stop-loss/reversal point that follows the trend.
SAR=SARₚᵣₑᵥ+AF×(EP−SARₚᵣₑᵥ), AF starts at 0.02 and increases 0.02 each new extreme, capped at 0.20

Price above VWAP is bullish; acts as intraday support/resistance.

Volume up updates PVI, volume down updates NVI, accumulated by close return
NVI rising on low-volume days = "smart money" building positions (a bull-market sign).

>0 and rising = strengthening volume; confirms breakouts.
成交量分布图
Tallies the volume distribution across price levels.
Volume within the range binned by price; POC=price level with the most volume; VA=value area holding about 70% of volume
The POC and the upper/lower edges of the value area are strong support/resistance; HVN consolidates, LVN is easily traversed quickly.
成交量变动率
The speed of volume expansion/contraction.
VROC=(V−V n periods ago)/V n periods ago×100

持续图表形态
Examples: Triangles (symmetrical/ascending/descending), Flag/Pennant (target≈flagpole height), Wedge, Rectangle, Cup & Handle.
converging/parallel trend lines and break direction; target measured from pattern height
Volume shrinks during consolidation and expands on the break; breakouts in the original trend direction have a higher win rate.
反转图表形态
Examples: Head & Shoulders Top/Bottom (neckline break, target≈head-to-neckline height), Double Top (M)/Double Bottom (W), Triple Top/Bottom, Rounding Top/Bottom, V-shape.
peak-trough geometry + neckline break; target=projected pattern height
Neckline break + volume = confirmation; trade failed patterns in reverse.
单/双根反转K线形态
Examples: Hammer/Hanging Man (long lower shadow), Inverted Hammer/Shooting Star (long upper shadow), Bullish/Bearish Engulfing (later body engulfs prior), Doji (open≈close), Dark Cloud Cover/Piercing, Harami.
pattern matching on relative OHLC sizes and body/shadow ratios (CDLHAMMER, CDLENGULFING)

matching the direction, size and overlap of three candles (CDLMORNINGSTAR, CDL3WHITESOLDIERS)

Pullbacks to 0.382/0.5/0.618 often find support; 0.618 draws the most attention.
价格缺口
Price vacuum between adjacent candles, reflecting abrupt sentiment shifts.
Gap up: today's L>yesterday's H; gap down: today's H<yesterday's L
Breakaway gaps confirm a trend and rarely fill; exhaustion gaps signal the end; most common gaps get filled.
轴心点
Intraday support/resistance computed from the prior period's OHLC, common intraday.
PP=(H+L+C)ₚᵣₑᵥ/3, R1=2PP−Lₚᵣₑᵥ, S1=2PP−Hₚᵣₑᵥ
Price above PP is bullish; breaks of R/S often accelerate.
趋势线与通道
Lines connecting highs/lows depict direction and slope, copied in parallel to form a channel.
Fit ≥2 lows (uptrend) or highs (downtrend), channel=trend line+parallel line
A valid break below/above = possible trend reversal; sell high and buy low within the channel.
安德鲁分叉线

Median line=A pointing to the midpoint of BC; upper/lower tines pass through B, C and parallel the median
Touching the median often reverts; touching the outer tines often reverses.
斐波那契扩展
Projects target levels after a breakout.
Based on A-B-C: target=C+(B−A)×ratio, ratio 1.272/1.618/2.0/2.618

Jaw=SMMA(HL2,13) shifted forward 8; Teeth=SMMA(HL2,8) shifted forward 5; Lips=SMMA(HL2,5) shifted forward 3
Intertwined = sleeping (ranging); opening up with Lips>Teeth>Jaw = uptrend.
钱德预测振荡器

CFO=(C−regression forecast value)/C×100
>0 stronger, <0 weaker; sustained deviation signals trend strength or mean-reversion pressure.

质量指数
Identifies reversals via the expansion/contraction of the high-low range (directionless).
Ratio=EMA(H−L,9)/EMA(EMA(H−L,9),9), MI=Σ₂₅(Ratio)
Reversal bulge: rising above 27 then falling below 26.5 = possible reversal.
随机游走指数
Compares actual travel against a random walk to judge whether a trend is real.
RWI_H=(H−L n periods ago)/(ATR√n), RWI_L=(H n periods ago−L)/(ATR√n)
RWI_H>1 = significant uptrend (non-random); both <1 = no trend.
趋势强度指数
Measures trend strength by price deviation relative to a MA.
TII=100×Σpositive deviations/(Σpositive deviations+Σnegative deviations)
>80 strong uptrend, <20 strong downtrend; near 50 no trend.
