Hello QS,

I woud like to plot a 10 bar moving average as a drawing tool on a chart so I can grab it with the mouse button and move it arround. It woud be used for studying of J.M. Hurst's cycles.
Is it possible?

Hi,

What happens exactly when you move the moving average?

You could place them as envelopes that engulfs price data(a MA above price and a MA below).Hurst used to draw these fixed width envelopes manualy on paper. The width is based on 10 moving average displaced back in time but since it was made by hand I was looking for ploting the MA and placing them on or under price data by dragging with the mouse.

Best Answer

You can create the following formula:

y = Param("Y", 0, -19);
x = Param("X", 0, -6);
plot(ref(sma(14), x) + (y/10), '');

After that, click on "Update Indicator" (third icon) to dynamically update the X and Y values.
