Oops my mistake, the bottom ma is supposed to be 89 not 100. When changing
to 89 then both values are 10,826.3.
So bottom line is if you put '//' in front of plot statements on a price
chart with all formulas displayed, on my computer you will get different ma
depending on how many bars are showing. Still a bug.

Hi,
The top chart is with a blank price chart and ma applied per your last
e-mail. The bottom chart is a stock price chart with all formulas. Note the
red ma just at top of price line at around 13:00 hours. Note top chart
slightly below. And off to left are other notable differences. Now for
another weird thing. When + or minus the whole chart the ma stay in the same
place, unlike previous sent pictures. So, on the main price chart (top) all
formulas have been erased and then the bottom chart is a saved stock price
chart with all formulas but with '//' in front of plot statements. Thus
either way I believe there is a diff of display of ma, thus a bug.
Am surprised that if you put the '//' in front of plot on stock price chart,
you do not get my problems. Also, on stock price chart there are NO have
'StyleOwnScale' checked.

Ps after the screen shot I went back and displayed the green ma and it is
10,826.3 not 10,829.6, thus two ma for the same price data.

Jerry,
I don't see any of the problems you describe and I've been using this new
version
for sometime now.
I should have also mentioned to check that all of the parameters, like
'Price'
and whatever other indicators are on the chart do NOT have 'StyleOwnScale'
checked.
If you can get the size of your graphics files down to around 50kb post a
shot of
your parameters window or send it to me privately if you like.
Here is a simple formula, when you get the time paste it into
a new indicator then apply and let us know whether you see the same problem.
(Be care of line wraps)
_SECTION_BEGIN("Price");
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo
%g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) )
));
Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle |
ParamStyle("Style") | GetPriceStyle() );
_SECTION_END();
_SECTION_BEGIN("MA");
P = ParamField("Price field",-1);
Periods = Param("Periods", 89, 2, 200, 1, 10 );
Plot( MA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ),
ParamStyle("Style") );
_SECTION_END();
