With the correction "==" to "=" your code works as it should.
remove it from the chart window and "apply indicator" again.

Re: [amibroker] Help with formula
have a look at code below Anthony.
I guess it could be programmed using arrays only, not sure,

Keith,
Have you tried the formula ? I made the
adjustments as you stated still does not work...although
I had them the way you suggested earlier...I
have been trying but something is not working properly.
Description:
When there is a new buy or sell signal the
cumCst will reset to 0.10 and increment by 0.003
until it gets to a maximum of 0.13, this is not
happening with the formula below....I can not
see the error, can anyone ?
Here is the complete formula
Buy=Cross(C,EMA(C,19));
Sell=Cross(EMA(C,19),C) ;
CumCst=0.00;
poslong=0;
posshort=0;
for (i=1; i
< BarCount; i++)
{
if(Buy[i])
{
poslong=1;
posshort=0;
CumCst[i]=0.10;
}
if(Sell[i])
{
poslong=0;
posshort=1;
CumCst[i]=0.10;
}
if(posshort)
{
if(C[i] < C[i-1])
CumCst[i] =
CumCst[i-1] + 0.003;
else
CumCst[i] =
CumCst[i-1];
}
if(poslong)
{
if(C[i] > C[i-1])
CumCst[i] =
CumCst[i-1] + 0.003;
else
CumCst[i] =
CumCst[i-1];
}
if(CumCst[i] > 0.13)
CumCst[i] = 0.13;
}
per=19;
Smth=2/(per+1)+CumCst;
MovAvg=AMA(C,Smth);
Plot(movavg,"",colorBlue,1);
Plot(C,"",1,64);
PlotShapes(Buy*shapeUpArrow,colorGreen,0,L,-20);
PlotShapes(Sell* shapeDownArrow,colorRed,0,H,-20);
Title="cumulative value = "+WriteVal(Cumcst,1.3);

Anthony --
I have added comments to your code below:
// Anthony.afl
Buy=Cross(C,EMA(C,19));
Sell=Cross(EMA(C,19),C) ;
CumCst=0.00;
poslong=0;
posshort=0;
for (i=1; i < BarCount; i++)
{
if(Buy[i])
{
poslong==1; // == doesn't set poslong to 1, it stays 0
posshort==0; // use = to set value
CumCst[i]=0.10;
}
if(Sell[i])
{
poslong==0;
posshort==1; // == doesn't set posshort to 1, it stays 0
CumCst[i]=0.10; // use = to set value
}
if(posshort) // posshort is 0 and code below is never executed
{
if(C[i] < C[i-1])
CumCst[i] = CumCst[i-1] + 0.003;
else
CumCst[i] = CumCst[i-1];
}
if(poslong) // poslong is 0 and code below is never executed
{
if(C[i] > C[i-1])
CumCst[i] = CumCst[i-1] + 0.003;
else
CumCst[i] = CumCst[i-1];
}
Keith,
Thanks...but that does not seem to be the
problem..when there is a signal
buy or sell...cumCST starts at 0.10 and
increments by 0.003 as per the
formula...that is not happening....it must
be something else
Anthony

The cumCST should increment up to .13 but it is not
happening..
