Projected Line for Bollinger Bands for the current and prior sessions

[outsource]

I think i get it.9-th argument was missing, which was for autoScale.Now it compiles and seems working as expected.

Thank you

One little handy thing I forgot to consult with you is the session count - accessable via properties.Is there a reference for that,as well ?To have the session count accessable via code menu.

Thank you

Hello outsource,

Please see this forum post for additional information on how you might expose the session count: http://www.ninjatrader.com/support/f...ead.php?t=4991

In the code example I created, the session count is stored in the variable:

bollingerSessionList.Count

so you would want to access it after:

if(Bars.FirstBarOfSession){/*...where the bollingerSessionList is updated*/}

Please let us know if we may be of further assistance.

i`m trying but cant just seem to figure out.Too good for me

Hello outsource,

You would use an IntSeries to store the session count at the current bar. Please see the example below:

Add these lines into your BollingerBandLines indicator

#region Variables
//...
[COLOR="SeaGreen"]private IntSeries sessionCount;[/COLOR]
//...
#endregion

protected override void Initialize()
{
//...
[COLOR="SeaGreen"]sessionCount = new IntSeries(this);[/COLOR]
//...
}

protected override void OnBarUpdate()
{
//...
//insert this below the if(Bars.FirstBarOfSession) condition
[COLOR="SeaGreen"]sessionCount.Set(bollingerSessionList.Count);[/COLOR]
//...
}

#region Properties
//...
[COLOR="SeaGreen"][Browsable(false)]
[XmlIgnore()]
public IntSeries SessionCount
{
	get { return sessionCount; }
}[/COLOR]
//...
#endregion

Then in your other indicator you would get the session count at the current bar by calling something like:

BollingerBandLines(2, 14).SessionCount[0];

Hi Michael,

thank you for the snippet provided.What do you mean ''in other indicator"?My intention was to access the session count in the BBLines indicator properties.It looks like the snippet you`ve provided is for the strategy usage.Or am i missing something?

Thanks a lot!

[NinjaTrader_MichaelM]

Hello outsource,

Can you please clarify what you mean when you say "My intention was to access the session count in the BBLines indicator properties."?

We would not set the sessionCount as a property as it is a dynamic variable based on how many sessions the indicator has data for. This value is determined primarily by how many "days to load" your chart is set to.

Do you wish simply to plot the session Count variable so it is visible in the Data Box?

Thank you in advance.

Hi Michaek,

I want to access the days coulnt just like i access the lines colors - via properties.To be able to set the number of days back via indicator menu, as i need to.Am i clear?

[NinjaTrader_MichaelM]

Hello outsource,

Changing the "Days to load" property will affect the chart and all indicators/strategies on the chart. Days and sessions are similar because usually one session occurs within one 24 hour period. So to use more or less sessions for the purposes of this indicator, you could change the "Days to load" property.

The "Days to load" property is not set in the indicator properties, it is set in the data series properties. The data series for the chart can be found by pressing CTRL + F while the chart is selected. You can change the number of days loaded by selecting the data series you want to change in the lower left-side box and changing the value next to "Days to load" in the right-side box and pressing OK.

Please see our help guide for more information: http://www.ninjatrader.com/support/h...s%2Bproperties

Hi MichaelM,

Is it possible to do the same trick with the linear regression indicator,i.e., to have projected lines from the prior session as with BB Lines,only this time to have the diagonal lines instead of the horizontal lines?If,so please suggest how.

Sincerely

[NinjaTrader_MichaelM]

Hello outsource,

You could accomplish this although it would be slightly more mathematically complex.

The basis of how the indicator works would be the same.

The only difference is that you would have to calculate the angle that you wanted to draw the line at using the imagined line drawn between two earlier points from the linear regression indicator and then convert that into the y value of the point the line would end at (the x value the line would end at would be 0 because its plotted using barsAgo).

Please let me know if you have any further questions.

Hi Michael,

no matter i try,i can`t seem to figure it out.Would you be willing to assist with it?I attach the indicator.

What`d really want is to kind of snap of the channel position at the session close and mirror /project it into the next session.
