Hello all,

I have got a, probably, simple problem to solve. I have to detemine the upper- as well as lower round figure to the actual price (rounded to 100 PIPS). Example: price = 1.12701; Upper round figure = 1.13000; Lower round figure = 1.12000.

This script is exactely doing that:

function main()
{
var Price = 1.12701;
var U_price= (ceil(Price*100)/100);
var L_price= (floor(Price*100)/100);

printf("Price: %.5f",Price);
printf("\nUpper Price: %.5f",U_price);
printf("\nLower Price: %.5f",L_price);
}



I get an error message with script below though:


function run()
{
vars Price = series(price());
var U_price= (ceil(Price*100)/100);
var L_price= (floor(Price*100)/100);

printf("Price: %.5f",Price);
printf("\nUpper Price: %.5f",U_price);
printf("\nLower Price: %.5f",L_price);



}

The error message says: Wrong type P_MUL:POINTER:LONG:POINTER

I have tried nopw everything I got out of the manual and GOOGLE, hope one of you guys can help me.

Many thanks in Advance.

In the bottom snippet, use Price[0] instead of Price to retrieve a particular element of your price series, where 0 is the element number.

Hi Andrew,

many thanks for the quick reply, it has worked ! Just that I got it right, the series function goes thru history bar by bar. The [0] index is the lates element of "Price", hence it would always use the current bar to claculate the rest right ?

Again Thanks !
