OWL Long Trading Alert: Entry Signal Methodology ExplainedOWL 多方交易警示:進場訊號方法論完整解析
What is OWL?
OWL (Opportunity Watch List) Long Trading Alert is AlpharvestPro's entry signal detection system. It identifies three specific low-risk buy points used by professional momentum traders:
- Pocket Pivot (PP) — A volume signal inside a base
- Buyable Gap-Up (BGU) — An earnings or news-driven gap that institutions support
- Undercut & Rally (U&R) — A shakeout trap that reverses into strength
These signals answer the most common question in momentum trading: "I found a strong stock — when exactly do I buy it?"
什麼是 OWL?
OWL(Opportunity Watch List)多方交易警示是 AlpharvestPro 的進場訊號偵測系統,用於辨識專業動能交易者所使用的三種低風險買進點:
- 口袋樞紐(Pocket Pivot, PP) ── 整理區間內部出現的成交量訊號
- 可買入跳空(Buyable Gap-Up, BGU) ── 由財報或重大消息觸發、且有法人買盤撐場的跳空
- 跌破回升(Undercut & Rally, U&R) ── 假跌破洗盤後反轉走強
這些訊號正面回答動能交易最常見的問題:「我已經找到強勢股,但到底什麼時候進場?」

Signal 1: Pocket Pivot (PP)
Definition
A Pocket Pivot occurs when a stock's up-volume on a given day exceeds the highest down-volume of the prior 10 trading days. Developed by Gil Morales and Chris Kacher, it identifies institutional buying within a base formation — before the stock breaks out to new highs.
Why it matters
Most breakout strategies require buying at or above a pivot point (often the prior high). Pocket Pivots let you enter earlier, inside the base, at a lower price with less risk.
Detection criteria
- Stock closes up on the day (close > open AND close > previous close)
- Today's volume exceeds the maximum down-volume of the past 10 days
- Today's volume is at least 1.5× the 50-day average volume
- Stock is above the 50-day moving average (or within 3% of the 200-day MA as support)
- Stock is not in a 65-day downtrend
口袋樞紐(PP)
#### 定義
口袋樞紐(Pocket Pivot)指的是某一上漲日,該日的上漲量超過過去 10 個交易日中「最大下跌日成交量」。此手法由吉爾·莫拉萊斯與克里斯·卡赫(Gil Morales、Chris Kacher)所提出,用於在個股突破創新高之前,提早辨識整理區間內的法人買盤。
#### 為什麼重要
大多數的突破策略,要求必須在樞紐點(通常是先前高點)或之上才買進。而口袋樞紐讓你在整理區間內就能更早進場,以較低的價格與較小的風險取得部位。
#### 偵測條件
- 當日股價收紅(收盤 > 開盤,且收盤 > 前一日收盤)
- 當日成交量超過過去 10 日的最大下跌日成交量
- 當日成交量至少為 50 日均量的 1.5 倍
- 股價站上 50 日均線(或在 200 日均線 3% 以內,作為支撐)
- 股價並未陷入 65 日下降趨勢

Signal 2: Buyable Gap-Up (BGU)
Definition
A Buyable Gap-Up occurs when a stock opens significantly higher than the previous close (gap up) on heavy volume — typically after earnings, a new product announcement, or positive guidance. Not all gap-ups are buyable; the key is institutional support evidenced by sustained volume.
Why it matters
A true BGU represents a sudden shift in institutional demand. The gap itself becomes a support zone — institutions that missed the gap will often buy pullbacks to the gap area.
Detection criteria
- Stock gaps up by at least 0.75× the 40-day ATR from the previous close (volatility-adaptive threshold)
- Volume on the gap day is at least 150% of average volume
- Stock closes bullishly (close ≥ open) and the gap is not filled (day's low stays above prior high)
- Stock is in an uptrend (price > MA50 > MA200)
可買入跳空(BGU)
#### 定義
可買入跳空指的是個股以遠高於前一日收盤價的價位開出(向上跳空),且伴隨大量成交量 ── 通常出現在財報公布、新產品發表或上修展望之後。並非所有跳空都值得買進,關鍵是要有法人買盤透過後續的成交量延續性予以支持。
#### 為什麼重要
真正的 BGU 反映了法人需求的急遽轉變。跳空缺口本身會成為一個支撐區 ── 那些錯過跳空當天的法人,通常會在股價拉回到缺口附近時加碼買進。
#### 偵測條件
- 跳空幅度至少為 40 日 ATR 的 0.75 倍以上(隨波動性自動調整門檻)
- 跳空當日成交量至少為均量的 150%
- 當日收紅(收盤 ≥ 開盤),且缺口未被回補(當日最低價維持在前一日高點之上)
- 個股處於上升趨勢(股價 > MA50 > MA200)

Signal 3: Undercut & Rally (U&R)
Definition
An Undercut & Rally occurs when a stock briefly breaks below a known support level (undercut), triggering stop-loss selling, then quickly reverses and rallies back above that level. It's a "shakeout" — weak hands sell, institutions buy the dip.
Why it matters
The U&R is a counter-intuitive signal. The undercut looks like a breakdown, which scares retail traders into selling. But when the stock immediately recovers, it proves that demand exceeded the temporary supply increase. The shakeout created a stronger base.
Detection criteria
- Stock breaks below the prior 20-day low, 50-day SMA, or 65-day EMA support level
- The break is brief — yesterday's low undercut the support level
- Stock rallies back above the broken level today (close > prior low) with a bullish candle (close ≥ open)
- No volume requirement — the price reversal itself confirms the shakeout trap
跌破回升(U&R)
#### 定義
跌破回升指的是個股短暫跌破已知支撐(假跌破),觸發停損賣壓,接著迅速反轉並重新站上該支撐價位。這就是所謂的「洗盤」── 散戶被洗出場、法人逢低承接。
#### 為什麼重要
U&R 是一種反直覺的訊號。假跌破看起來像是真的破底,讓散戶恐慌賣出。但當股價立刻收復失土,代表需求已超過短暫增加的賣壓。洗盤之後,反而打造出更扎實的整理區間。
#### 偵測條件
- 個股跌破前 20 日低點、50 日 SMA 或 65 日 EMA 等支撐
- 跌破時間極短 ── 前一日的最低價跌破支撐
- 今日股價反彈站回支撐之上(收盤 > 前日低點)且收紅 K(收盤 ≥ 開盤)
- 不要求成交量條件 ── 價格反轉本身就足以確認假跌破洗盤

FAQ
How many entry signals are generated per day?
It varies with market conditions. Typically 20-80 signals across all 4 markets during normal conditions. During strong uptrends, the number increases; during corrections, it drops to near zero (which is informative itself).
Can I get alerts for entry signals?
Currently, signals are published in daily reports and the X feed (@alpharvestpro). Real-time push notifications are planned for VIP subscribers.
Which signal type is most reliable?
BGU has the highest win rate because it represents the strongest institutional demand. PP is the most common and offers the best risk/reward due to early entry. U&R is the least common but can yield the largest gains when market conditions are right.
每天會出多少進場訊號?
數量視大盤環境而定。一般情況下,四大市場每日合計約 20-80 檔。在強勢上升趨勢中數量會增加;在修正期間則接近於零(這本身也是重要資訊)。
我可以收到進場訊號的即時通知嗎?
目前,訊號發布於每日報表與 X 平台(@alpharvestpro)。即時推播通知為 VIP 訂閱戶規劃中的功能。
哪一種訊號最可靠?
BGU 勝率最高,因為它代表最強的法人買盤。PP 出現頻率最高,因進場較早,風險報酬比也最佳。U&R 出現頻率最低,但若大盤環境配合得當,單筆獲利幅度可能最大。
