請教老大

Equis-MACD
裡面超買指標：
OscP(12,26,E,%) >= 3 AND ROC(OscP(12,26,E,%),5,$) = Sum(Abs(ROC(OscP(12,26,E,%),1,$)),5)
的Oscp、和Sum不是很理解，還有“%”請老大指導！謝謝！！！

Function: Price Oscillator [oscp()]

---

SYNTAX      

oscp( PERIODS, PERIODS, MA_METHOD, DIFF_METHOD )

FUNCTION     

Calculates the PERIODS/PERIODS predefined Price Oscillator indicator calculated using the MA_METHOD moving average method expressed in DIFF_METHOD.

Valid MA_METHODs are SIMPLE, EXPONENTIAL, WEIGHTED, TIMESERIES, TRIANGULAR, and VARIABLE (these can be abbreviated as S, E, W, T, TRI, VAR).

Valid DIFF_METHODs are PERCENT and POINTS (these can be abbreviated as % and $). 

EXAMPLE      

The formula "oscp(1, 25, E, $)" returns a 1-period/25-period exponential price oscillator expressed in points.

同樣係計算移動平均數值, 並且係以第1個參數除以第2個參數後移動平均數值, "$" 位係可選用 "%" , 即由價位轉為以 百份比顯示數值~

Function: Summation [sum()]

---

SYNTAX      

sum( DATA ARRAY, PERIODS )

FUNCTION      

Calculates a cumulative sum of the DATA ARRAY for the specified number of lookback PERIODs (including today).

EXAMPLE      

The formula "sum( CLOSE, 12 )" returns the sum of the preceding 12 closing prices. A 12-period simple moving average could be written "sum(C,12) / 12."

SUM  總括來說係將結果加總意思, 後面數字代表, 將之前幾多日結果總加起來~
