double why not work ?

[Stefano Cerbioni]

hi guys  i  have a questions

i have indicator at end of this indicator i divide two double and after i multiplay for constant 100  why return  100 ?????????

if i print a single  double return number little like 0.000232335  or 9.88888  but  when i  divide  return always  1  how is possible that ???

Set your arrays to as-series before filling them (so iMAOnArray knows how to read them), or make them buffers.

Thank you so much I bow to your genius thank you again

holy immediately
