Total Power Indicator(MetaTrader 指標)[MT5公式]

該指標適用于MT4和MT5。

該指標基于兩種標準指標 — 看跌能量和看漲能量。計算了在設定的回溯時期內多頭和空頭的數量，然后計算當前時期內空頭、多頭以及總體（多空差異）比例指標。這樣，去除掉原始空頭/多頭能量指標中的主要缺陷 — 缺乏長期預測，我們就得出一定時期內空頭和多頭能量相對平均的連續的走勢線。

輸入參數：

• LookbackPeriod (默認 = 45) — 該指標的主要時段。決定著用以計算支配空頭/多頭的數量的回溯天數。
• PowerPeriod (默認 = 10) — 原始Bear Power 和 Bull Power 指標中的時段。

該指標有多種不同的使用方式：

1. 成功率最高的進場方式（但也是出現的次數最少的）是等多頭（或空頭）和總線都顯示為100的值時，進場做多（如果是空頭線，進場做空）。
2. 空頭和多頭線交叉也可進場交易。如果多頭線在上方 — 做多，如果空頭線在上方 — 做空。
3. 多頭和空頭線與總線的交叉可作為進場或離場的信號。如果多頭線從下方與總線交叉，進場做多，如果空頭線從下方與總線交叉，進場做空。如果這些線從上方與總線交叉 — 關閉相應的頭寸。
4. 替代方式是用一定的指標水平替代交叉作為進場信號。
