Custom indicator to draw to the right of the chart

Hi,

I'm writing an indicator that will try to guess details of the price action in the future. And so I'd like it to plot it's values at the correct future bars (to the right of the latest bar of the price chart).
What I want it to look like is if you add a MA indicator to the chart and set the Shift parameter to a value other than 0. Then the MA plot will move to the right or left (of Shift>0 or Shift<0). So if Shift>0 the MA line looks like set to the future.
How could I have this efect with a custom indicator?

This guy had the same idea.

Many thanks for the link! The function I was looking for turns to be void SetIndexShift(int index, int shift)
