[amibroker] Re: how to code this

[das300@xxxxxxxxxx]

SORRY SORRY dudes  ,
I think I stuffed up my formula . Can I re type what I want.

not taking into account syntax what i want is - 

value = initvalue + value[i-1] + value[i-1]* variable_X 
      = initvalue +   value[i-1]*( 1+ variable_X ) 


initval = valuewhen(cum(1) == 1 , c ) ; // first close of chart ;
// value[i-1]  means previous value calculated .
// i = nth bar
// variable_X = say 0.01 ;

EG- 

initval = valuewhen(cum(1) == 1 , c )  say on bar 1 = 1.00 ; 
variable_X = say 0.01 ;

value         = initvalue +   value[i-1]*( 1+ variable_X ) 
value @ bar 1 = $1.00 + 0 * ( 1+ 0.01 ) = 1.00
value @ bar 2 = $0    + 1.00  * ( 1+ 0.01 ) = 1.01
value @ bar 3 = $0    + 1.01 * ( 1+ 0.01 ) = 1.021
value @ bar 4 = $0    + 1.021 * ( 1+ 0.01 ) = 1.12211 etc

thanks :-)
