Sorry, Correction, this one does not count the buy day in the barssinceEntry.
Buy = Cross( MACD(), Signal());
Sell=Cross(Signal(),MACD());
BarsSinceentry =0;
poslong=0;posshort=0;
for( i = 0; i < BarCount; i++ )
{
if( Buy[i])
{
poslong=1;posshort=0;
}
if(Sell[i])
{
poslong=0;posshort=1;
}
if(poslong==1)
{
if(Buy[i])
BarsSinceentry[i]=0;//BarsSinceentry[i-1]+1;
else
{
if(poslong==1)
BarsSinceentry[i]=BarsSinceentry[i-1]+1;
}
}
}
Days=BarsSinceentry;
Plot(C,"",colorBlack,styleCandle);
PlotShapes(Buy*shapeUpArrow,colorGreen);
Title=Name()+ " BarsSinceBuy [ "+WriteVal(Days,1)+ "]";

Owen,
This is coded for the Buy side of the signal, load into Indicator builder, make sure that scaling is set to automatic...it seems that when you open a new formula window in Indicator builder it defaults to Custom scaling....you will see in the title the number of bars since buy...
it resets at every buy signal, currently it shows 0 for sell side......does this help ?

That is the only way I can see to do it, but the task is beyond me.
That's why I keep goosing Tomasz every six or ten months. It's a
function I really believe should be built in.
