Accumulation distribution formula larry william for stocks

[lion1980]

hello..
I'm reading an old book by Larry William that says:

"In a concise form the equation is this: Close minus the opening, divided by high
minus the low, times daily volume = net buying or selling volume for the day (net
daily A/D figure).

This is equated as :
close-open
-----------------
high -low X total volume = net buying or selling pressure for the day."

can you help me write this indicator?please

thank you very much

Hello lion1980, thanks for your note.

The first thing the script will need is a secondary daily series. This will let us get the daily volume. Use AddDataSeries() to add a daily series.

After this, in BarsInProgress == 0, perform the calculation:

[I]protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                ...
                AddPlot(Brushes.Red, "MyPlot");
            }
            else if (State == State.Configure)
            {
                AddDataSeries(BarsPeriodType.Day, 1);
            }
        }

        protected override void OnBarUpdate()
        {
            if(CurrentBars[1] < 1 || CurrentBars[0] < 1)
                return;

            if(BarsInProgress == 0)
            {
                Value[0] = (Close[0] - Open[0])/((High[0] - Low[0])*Volumes[1][0]);
            }

        }[/I]
