Formula Variable Call

alice

Matthew 大師/大大師兄，

在EST，當一個SYSTEM已經寫滿了，但又要加更多formula(with OPT)，例如要加"OR RSI(14)>70 AND C>OPT8"

Q1) 除了用EXTFML，有無簡單方法可RECALL額外的formula?

Q2) fmvarl()是點用的?睇咗都唔明...可唔可以解決以上問題呢?

 

 

 

 

Function: Formula Variable Call [fmvarl()]

---

SYNTAX      fmlvar( "FORMULA_NAME", "VARIABLE_NAME")

FUNCTION      Calls the custom indicator named FORMULA_NAME and returns the value contained in the custom indicator's variable named VARIABLE_NAME.

Notes:

    Both the formula's name and the variable's name must be contained in quotation marks
(e.g., fmlvar( "Secret A", "MyVar")).

    If you change a formula or variable name, you must also change any fmvarl() calls that reference that formula and variable.

EXAMPLE      fmlvar("MyIndicator", "MyVariableA" )

可以 !  

fmlvar( "FORMULA_NAME", "VARIABLE_NAME")

 

人地寫得好清楚喎, 你睇真:
Calls the custom indicator named FORMULA_NAME and returns the value contained in the custom indicator's variable named VARIABLE_NAME.

 

e.g.  你有一個 自制的 indicator  "my moving average"

內容如下:
mymov := mov(C,10,S);

mymov

那 "mymov" 這個便是 "VARIABLE_NAME"

 

你調用時便要這樣:
var1 :=  fmlvar( "my moving average", "mymov")

這樣便可以將該 自制技術指標的 "mymov" 值, 調用到你其它的公式中 !!

明白晒!Matthew 大師說的容易明白好多!
謝謝Matthew 大師!
