Volume Spike Indicator

[RK_trader]

Hi

Anyone know if there are any indicators for volume spikes. Something like an audio alert or some chart marking on a volume spike like in a 1 min or a 5 min chart.

Thanks
RK

I don't know of any preexisting ones, but you can definitely make one with no problem. You could do something like

if (Volume[0] >= Volume[1] * 1.10)
     PlaySound("Alert1.wav");

or if you wanted a draw object you could do

if (Volume[0] >= Volume[1] * 1.10)
     DrawDiamond("Volume Spike" + CurrentBar, 0, Low[0] - TickSize, Color.Red);

Thanks Josh. I appreciate it.

If possible can you or anyone please add this code to a down oadable indicator file (.zip). I am still learning Ninja programming and am able to edit/play with an existing indicator by modifying the code. Have to learn how to build a new one from scratch

I appreciate it.

Thanks

I usually just use the NinjaScript wizard to generate the template for my indicator and just put in my algorithms into the OnBarUpdate() section.

Thanks Josh. I appreciate it.

Any suggestions from anyone on which values the "spike" field in indicator should be? I tried "2" it was able to catch some spikes which met those conditions. So, for value of 2, the indicator is catching only volume spikes which are atleast 2 times greater than the previous volume bar. For example, if one bar is like 1000 contracts, and the next bar is like 3100 contracts, the indicator alerts.

Any suggestions on improving the condition of the spike, something like greater than the average of last two bars or some combination like that?

Thanks

try using the average volume(2) indicator instead of the volume indicator...

Hi Bertrand,

Any chance you can add an alert to it?

Thanks

Hi,

You can easily edit this indicator to add your own custom alert

			if (Volume[0] >= Volume[1] * (1 + Spike))
            {
     			DrawDiamond("Volume Spike" + CurrentBar, true, 0, Low[0] - TickSize, Color.Gold);
               [B] Alert("myAlert", NinjaTrader.Cbi.Priority.High, "Reached threshold", "Alert1.wav", 10, Color.Black, Color.Yellow);[/B]

            }

Many thanks Mat,seems working well.How do you add an alert to this: (attached)

SnakeEYE, you would key off the trend dataseries here exposing the internal signal of the technique.
So for example for an upswing you could check -

if (Trend[0] == 1 && Trend[1] == -1)
	Alert("myAlert1", NinjaTrader.Cbi.Priority.High, "up swing", "Alert1.wav", 10, Color.Black, Color.Yellow);

Hi Bertrand,

By ''key off'' you mean something like the double or tripple right slashes -'///'?

If so,where i put them in the code?

{
Trend.Set(Close[0] >= Open[0] ? 1 : -1);
Value.Set(Trend[0] == 1 ? Low[0] : High[0]);
return;
}

if(Trend[1] == 1)
{
double higherLow = Math.Max(Value[1], Low[0]);

if (High[0] < higherLow - TickSize * 0.01)
{
Trend.Set(-1);
Value.Set(High[0]);
}
else
{
Trend.Set(1);
Value.Set(higherLow);
}
}
else
{
double lowerHigh = Math.Min(Value[1], High[0]);

if (Low[0] > lowerHigh + TickSize * 0.01)
{
Trend.Set(1);
Value.Set(Low[0]);
}
else
{
Trend.Set(-1);
Value.Set(lowerHigh);
}
}

PlotColors[0][0] = Trend[0] == 1 ? ColorUp : ColorDown;

if (PaintBars)
BarColor = PlotColors[0][0];
}

Sorry I'm not following you, with key off I meant for your signal / alert the trend series offered is then where you want to work with closely, as it would directly offer you what's needed to setup the alert condition. The snippet I've shown could be entered for example in the OnBarUpdate() below the paint bar condition.
