I din't have it but the coding of this indicator would not be hard.
This is the formula for it:
To calculate the Williams' Accumulation/Distribution indicator,
determine:
True Range High (TRH) = Yesterday's close or today's high whichever
is greater
True Range Low (TRL) = Yesterday's close or today's low whichever is
less
The day's accumulation/distribution is then calculated by comparing
today's closing price to yesterday's closing price.
If today's close is greater than yesterday's close: Today's A/D =
today's close - TRL
If today's close is less than yesterday's close: Today's A/D =
today's close - TRH
If today's close is the same as yesterday's close then the A/D is
zero.
The Williams' Accumulation/Distribution indicator is a cumulative
total of the daily values:
Williams A/D = Today's A/D + Yesterday's Williams A/D
Thus, the Williams' Accumulation/ Distribution indicator is used to
determine if the Forex market is controlled by buyers (accumulation)
or by sellers (distribution); and trading when there is divergence
between price and the A/D indicator.
The Williams A/D indicator recommends buying when prices fall to a
new low, yet the A/D indicator fails to reach a new low. Likewise,
sell when the price makes a new high and the indicator fails to
follow suit.
The code follows:

/*To calculate the Williams' Accumulation/Distribution indicator,

The Day's accumulation/distribution is then calculated by comparing
today's closing price to yesterday's closing price.
if today's Close is greater than yesterday's Close: Today's A/D =
today's Close - TRL
if today's Close is less than yesterday's Close: Today's A/D =
today's Close - TRH
if today's Close is the same as yesterday's Close then the A/D is
zero.

TRH = IIf(Ref(C, -1) > H, Ref(C, -1), H);
TRL = IIf(Ref(C, -1) < L, Ref(C, -1), L);
ad = IIf(C > Ref(C, -1), C - TRL, IIf(C < Ref(C, -1), C - TRH, 0));
WAD = Cum(ad);
Plot(WAD, "Williams AD", colorBlue);
