RE: [amibroker] Self Referencing Formula

["Herman van den Bergen" <psytek@xxxxxxxx>]

// PREV

Z =(A*B)+(C*PREV);

can be written in AFL as:

Z = AMA2( A(array), B, C );

also:

xx = FactorA * Close + (FactorB * PREV(xx)); // metastock

translates to:

xx = AMA2( Close, FactorA, FactorB );

Group,

I would like to see some working code for a Self Referencing Formula.
That is where the previous value of the indicator is used in
calculating the new value of the indicator.  Ref() doesn't
automatically initialize itself - like MetaStock does.

The problem is with how to initialize the array.  The pseudo-code
might look like:

Start:
On the first bar set Arg = Close;

On the next pass, do some math and calculate "Factor(Arg)"

Then
   NewArgVal = Factor * Arg;
   Arg = NewArgVal;
   Plot NewArgVal;

Loop to Start.
