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" )
