--------------------------------------------------------------------------------

 

//The following code will return a 1 when the negative DMI crosses above the positive DMI.

mdmi = MDI(13);

pdmi = PDI(13);

NEGdmicrossing = Cross(mdmi,pdmi);

POSITIVEdmicrossing = Cross(pdmi,mdmi);

Buy=POSITIVEdmicrossing ;

Sell =NEGdmicrossing;

BarsSince( POSITIVEdmicrossing ) ;

BarsSince( NEGdmicrossing ) ;

 

Filter=Buy OR Sell;

AddColumn(Sell,"SELL",format=1.2);

AddColumn ((BarsSince( POSITIVEdmicrossing )), "uptrend ",format=1.0);

AddColumn ((BarsSince( NEGdmicrossing )), "downtrend ",format=1.0);

The following code will return a 1 when the negative DMI crosses above
the positive DMI.

mdmi = MDI(13);
pdmi = PDI(13);
dmicrossing = Cross(mdmi,pdmi);

However, what I want to know is how many days have passed since the
negative DMI crossed above the positive DMI.  I have looked through the
AFL formulas for a Days Since Crossing function but did not find one.
Can anyone help me with the code to perform this function?

Thanks,
Alan
