Prior to upgrading to version 4.3, the following code worked. Now I'm
getting the error message ...
Unknown identifier at line 29, column 10:
Plot (RelRocOfPrice, "RelRoc of Price", barcolor, styleLog |
-----------------------------------------------------------^
BTW, this indicator code is placed in the builtin price indicator
formula.
//Start of indicator code
Period = 107;
UpDay = C > Ref(C,-1);//define an up day
UpDays = Sum(UpDay, Period);//# of up days in the period
AvgUpRoc = MA(ROC(C,1) * UpDay,UpDays);//Average of the 1-day ROCs
for up days over the lookback period
RelUpRoc = ROC(C,1) / Ref(AvgUpRoc,-1);//Today's 1-Day ROC compared
to yesterday's AvgUpRoc
DnDay = C < Ref(C,-1);//define a down day
DnDays = Sum(DnDay, Period);//# of down days in the period
AvgDnRoc = MA(ROC(C,1) * DnDay,DnDays);//Average of the 1-day ROCs
for down days over the lookback period
RelDnRoc = -(ROC(C,1) / Ref(AvgDnRoc,-1));//Today's 1-Day ROC
compared to yesterday's AvgDnRoc
RelRocOfPrice = IIf(UpDay,RelUpRoc-1,RelDnRoc+1);
BarColor = IIf(UpDay, colorDarkGreen, IIf(DnDay,
colorRed,colorBlack) );
Plot (RelRocOfPrice, "RelRoc of Price", barcolor, styleLog |
styleOwnScale | styleHistogram); // THIS IS THE PROBLEM LINE
Plot(MA(RelRocOfPrice,3),"",colorLightBlue,styleHistogram |
styleThick | styleOwnScale);
//--Indicator-End--
If I remove the styleLog parameter from the problem line, the error
message goes away, but the indicator no longer plots as a histogram.
It plots all lines starting from the bottom of the pane. I have
Logarithmic checked at the bottom of the indicator builder, as I want
to price plotted using a logarithmic scale.
Can someone spot the problem? Help appreciated.
