Hi, just a quick question on MQL...

when i retrieve a value from custom indicator using the following

rsx1 = iCustom(NULL,0,"JJRSX",10,3,0,0,1);

the value is returned just fine...

but when i retrieve a series of values from the indicator like this

for (i=100;i>=0;i--)
{ ExtMapBuffer[i] = iCustom(NULL,0,"JJRSX",10,3,0,0,i);

i get zeros...why is that?? can anyone help ?

Hi there,

Your code looks correct. If I were to guess I would say you have probably declared your array as int, instead of as double.

Hi,
Thanks for the reply.but i did declare it was double....not sure why it is still returning zero....the loop works fine but each value of the array is 0....

Did you declare it as size [101] or did you leave the size out ie []

Hi there,

Yup, the array needs to know the size.......not sure why, but my tests show zeros if the array size is not defined. If you using a fixed loop, then set the size to [101].

You can always dynamically resize later in the program using ArrayResize.

Hi there,

Nah, not really. I pick little projects here and there to work on.
