Hi
I wish to have the price volume trend indicator show a colour change and alert when the current period is higher than the previous period and when the current period is lower than the previous period.

so far I have this code


_VT:= ((Pr - ref(Pr,-LBP))/ref(Pr,-LBP)) * V) + PREV(0);
_PVT:= *beep*(_VT);

_UpPVT:=if(_VT>=ref(_VT,-1),_VT,_VT);
_DownPVT:=if(_VT<ref(_VT,-1),_VT,null);

LongSignal:=SignalRemove(_VT>ref(_VT,-1),_VT<ref(_VT,-1));
ShortSignal:=Signalremove(_VT<ref(_VT,+1),_VT>ref(_VT,+1));

Could i please get help on how to code this up as i have tried having the variables as both _VT and _PVT and still nothing :|

Regards and thanks,

-Mike.

Hello,

Your _UpPVT and _DownPVT output variables need to be your "Indicator Output Enabled" variables and the _PVT variable should *not* be "Indicator Output Enabled". Change your code to this:

_UpPVT:=if(_PVT>=ref(_PVT,-1),_PVT,_PVT);
_DownPVT:=if(_PVT<ref(_PVT,-1),_PVT,null);

This should take care of the bi-color portion of the indicator.

For the alerts, change your LongSignal and ShortSignal code to the following:

LongSignal:= Cross((_PVT>=ref(_PVT,-1)),0.5);
ShortSignal:= Cross((_PVT<ref(_PVT,-1)),0.5);

The LongSignal and ShortSignal output variables should be at least "Alerts Enabled" and probably "Graphics Enabled" as well. Be sure you go to those respective tabs (Graphics and Alerts) and configure the settings.

You're welcome.

What does the final code look like if you can share? I have similar idea.
