try this,
hth,
ron
//S&C june 2004 TJ
Period = Param("VFI Period", 26, 26, 1300, 1 );
Coef = 0.2;

inter = log( Avg ) - log( Ref( Avg, -1 ) );
Vinter = StDev(inter, 30 );
Cutoff = Coef * Vinter * Close;
Vave = Ref( MA( V, Period ), -1 );
Vmax = Vave * Vcoef;
Vc = Min( V, VMax );
MF = Avg - Ref( Avg, -1 );
VCP = IIf( MF > Cutoff, VC, IIf ( MF < -Cutoff, -VC, 0 ) );

Subject: [amibroker] Exploration Help!
Hi gang, I'm stuck trying to code this exploration. Its a basic
cross above or below the EMA of the Volume Flow Indicator...but Its
not working. Can anyone point me in the right direction please.
Here's what I have so far:
Period = Param("VFI Period", 26, 26, 1300, 1 );
Coef = 0.2;
VCoef = Param("Max. vol. cutoff", 2.5, 2.5, 50, 1 );
inter = log( Avg ) - log( Ref( Avg, -1 ) );
Vinter = StDev(inter, 30 );
Cutoff = Coef * Vinter * Close;
Vave = Ref( MA( V, Period ), -1 );
Vmax = Vave * Vcoef;
Vc = Min( V, VMax );
MF = Avg - Ref( Avg, -1 );
VCP = IIf( MF > Cutoff, VC, IIf ( MF < -Cutoff, -VC, 0 ) );
VFI = Sum( VCP , Period )/Vave;
VFI = EMA( VFI, 3 );
Plot( VFI, "VFI", colorBlack, styleThick );
Plot( EMA( VFI, 7 ), "EMA7 of VFI", colorBrown );
Plot( V, "Volume", IIf( VCP > 0, colorGreen, IIf( VCP < 0, colorRed,
colorBlue ) ),
styleHistogram | styleOwnScale | styleNoLabel );
// VFI MA crossover
Buy = Cross( VFI, EMA );
Sell = Cross( EMA, VFI, );
Cheers Bruiser
