If I want to convert my “Daily Pivots on Intraday Chart” to
only plot the last two days, would the following be the correct adaptation to
your code?
<span
>Dm:=If(Hour()<=Ref(Hour(),-1),1,0);
<span
>PP3:=If(Dm=1,(Ref(HighestSince(1,Dm=1,H),-1)+
<span
>Ref(LowestSince(1,Dm=1,L),-1)
+
<span
>Ref(C,-1))/3,0);
<span
>Mh1:=If(Dm=1,Ref(HighestSince(1,Dm=1,H),-1),0);
<span
>Ml1:=If(Dm=1,Ref(LowestSince(1,Dm=1,L),-1),0);
<span
>Mh:=ValueWhen(1,Mh1>0,Mh1);
<span
>Ml:=ValueWhen(1,Ml1>0,Ml1);
<span
>PPM:=ValueWhen(1,PP3>0,PP3);
<span
>R1:=(2*PPM)-Ml;
<span
>S1:=(2*PPM)-Mh;
<span
>S3:=ppm-(Mh-Ml);
<span
>S2:=S1-(R1-S1);
<span
>R2:=R1+(R1-S1);
<span
>R3:=ppm+(Mh-Ml);
<span
>evm:=(mh-PPm)+ml;
Condition:=<span
>r2;r3;r1;ppm;s1;s3;s2;<font
size=2 face="Courier New"> {signal true for
several bars}<span
>
Condition:=Condition AND Alert(Condition=0,2);
{converted to one bar signal}
Trigger:=LastValue(Cum(Condition)-1)>=Cum(Condition);
ValueWhen(1,Trigger,"support value");

Yes there is a way to do this. By using the
ValueWhen() function you can manipulate the full signal
plot so that only that portion of the plot from
the most recent event will display. You may find,
however that it is more useful to start the plot
at the second most recent event so that you are
never left with a single bar plot (most recent
event occurred on the last bar). When this happens
the plot can be very difficult to see because it
is only a small spot.
You can achieve a "trigger" for
ValueWhen() by first counting every event. For easiest use it would
probably be helpful if "the event" is
restricted to one bar only. By counting these events using
Cum("event") and comparing that against
LastValue(Cum("event")) you can create a signal for the
"condition" portion of ValueWhen(). Your
code might look something like this.
Condition:="your multiple bar signal";
{signal true for several bars}
Condition:=Condition AND Alert(Condition=0,2);
{converted to one bar signal}
Trigger:=LastValue(Cum(Condition)-1)>=Cum(Condition);
ValueWhen(1,Trigger,"support value");
Remove the "-1" from the trigger
variable if you really do want to trigger on the last value. You
may also need to change ">=" to
"=" or "<=".
If you can't make my suggestion work then ask
again. I know the method works but getting the detail
correct can be a little tricky. Any real world
example I give is going to need to be adapted before
it will work for you so I have not attempted to
provide something you can simply cut and paste.
Think through the issues and ask more questions if
it's not clear.
