Guidance on how to refresh indicator values on every tick.

[nandishop]

Here is the EFS. Its does not refresh values!! What's is missing? Am a new user. Help would be greatly appreciated..


Formula Parameters: Default:
Numbers of Period 10
Multiplier 3

Try replacing this code block:

 var nUp = 0, nDn =0, nTrendDir = 0;
 nUp = xUp.getValue(0);
 nDn = xDn.getValue(0);
 var vTrend = xTrend.getValue(0);
 if (nUp == null && nDn == null && vTrend == null) return; 

With:

 var vTrend = xTrend.getValue(0);
 if (vTrend == null) return; 

The removed variables are not used inside the main function. That said, when I tested in briefly it updated on a 1 minute and 100T chart.
