indicator plotting only close instead of my custom value

[junkone]

i am trying this in market analyser and why does this code keep plotting the close price instead of my custom 1 if condition matches.

///</summary>
protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
CalculateOnBarClose = false;
Overlay = false;
PriceTypeSupported = false;
}
///<summary>
/// Called on each bar update event (incoming tick)
///</summary>
protectedoverridevoid OnBarUpdate()
{
if(FirstTickOfBar || (VolumeMA==null)){
VolumeMA=triggerRatio* EMA(Volume,15)[1];
}



// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
if(Volume[0]>= VolumeMA){

Plot0.Set(1);
}

}

Please run it on a chart and try to debug it to see where the values are set. If you are on CalculateOnBarClose = false you need to set the value of the bar on every single tick if you want it to persist.

you can see how i added my indicator to the chart

http://screencast.com/t/75mP33tqS

it shows that it took parameter of 2.
the chart looks excatly like how my indicator should work
the indicator shows orange line when the criteria matched.
The market analyser is showing the price plotted for the same indicator and same parameters. my indicator does not plot the price at all.

i dont know where the market analyser is getting it from.
protected override void OnBarUpdate()
{
if (CurrentBar<20)
return;


if(FirstTickOfBar || (VolumeMA==null)){
VolumeMA=triggerRatio* EMA(Volume,15)[1];
}



// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
if(Volume[0]>= VolumeMA){

Plot0.Set(1);
}
}

I suggest you add some Print() lines into your indicator then and run it from the MA while examining the Output Window.

pl explain something to me. why does the market analyser show something that is not shown in the chart window for the same indicator.
i have only 1 plot statement in my code which is
Plot0.Set(1);

[NinjaTrader_JoshP]

Please Print() values to see what your indicator is doing. I cannot explain anything until we get some debugging going.

{
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
CalculateOnBarClose = false;
Overlay = false;
PriceTypeSupported = false;
}

protectedoverridevoid OnBarUpdate()
{
if (CurrentBar<20)
return;


if(FirstTickOfBar || (VolumeMA==null)){
VolumeMA=triggerRatio* EMA(Volume,15)[1];
}

if(Volume[0]>= VolumeMA){

Plot0.Set(1);
Print( "inside Plot" + Plot0[0]);
}
Print( "Outside Plot" + Plot0[0]);
}

IT seems to be assigning the price somewhere. but i dont see my code doing it.
the PRint statemetn is printing the price even though i am not assigning it anywhere.

When you don't set the plot, it automatically takes the price. Please follow the suggestion in post #2.

1. why is there a differece in behaviour between a market analyser and the chart. the chart did not show any values at all for the bars i did not set the value.
2. what value can you set when there is none to set?
if(Volume[0]>= VolumeMA){

Plot0.Set(1);
}

else
{
// what value do i set
Plot0.Set(?);
}

[NinjaTrader_JoshP]

1. For sure there is a difference. Especially in regards to how many bars lookback there is. If you want to know what is going on with your indicator you need to follow the values on every single step. See when it takes the 1. See when it does not take it.

2. You need to decide what you want that value to be. Whether that is set what it is from your previous set, or a new value.

[junkone]

i dont want any values to. would it take a null or something like that.

[NinjaTrader_JoshP]

That is not the issue here. You need to set it on EVERY single tick if you want your setting to persist.

Tick #1 of bar = you set plot to 1
Tick #2 of bar = you fail to set the plot value therefore the plot is now taking on values of the close price
Tick #3 and so on = will continue to take the close price because you are not setting the plot to 1.

Therefore MA = you see close price.

If you want to set a null value please read this article for the .Reset section. http://www.ninjatrader-support.com/H...taSeriesObject

ok. i understand that there is dummy close value set for each bar. does the reset set the value of the bar back to the dummy value or does it provide zero value for the bar.
i tried
Plot0.Reset(0);

and it put the close value back to the bar in market analyser. how do i get a novalue for the bar?

[NinjaTrader_JoshP]

It will hold a dummy value. I suggest you just set the plot to 0.
