Calling Indicator for Multi Timeframe

[tshirtdeal]

I am trying to call an indicator in a script for multi timeframe so that my charts do not look all messed up after holidays (Equi spacing = True instead of loading the data series)


I did this:


protected override void Initialize()
{
Add(PeriodType.Minute,2);
Overlay = false;
}

and I do this:

if (BarsInProgress == 0)
MEFLinRegAngle(Closes[1],60,14,3,9,3,false);

which from what I read is correct, can someone help me understand why it will not plot the indicator at all?

Thanks,
R.T.

Hi R.T,

Please check log tab of control center for any error messages. Multiseries scripts will need something like the following to prevent accessing data objects before they exist:

if (CurrentBars[0] < 0 || CurrentBars[1] < 0) return;

Add that to first line of OnBarUpdate()

Thanks Ryan,

I added this:

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate ()

{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
if (CurrentBars[0] < 0 || CurrentBars[1] < 0) return;
if (BarsInProgress == 0)
MEFLinRegAngle(Closes[1],60,14,3,9,3,false);

but still does not plot...

Are there any error messages in log tab of control center?

[tshirtdeal]

Yes, sorry,

on Bar 0 : Index was out of bounds of the array"

[NinjaTrader_RyanM1]

You may have to play with the values there on CurrentBars[1], in case your indicator does any indexing for past values. Try with < 20 and then adjust up/down as needed.

If you're still not able to see a plot, please share the indicator script and let us know the primary series interval you're applying this to.

Thanks,

tried everything inbetween nad it still will not plot, no new errors reported in the log

I am applying this to a 5 minute primary... I attached the indicator

[NinjaTrader_RyanM1]

Thanks for the file. Where are you setting the plot in your own indicator? This line you included from earlier doesn't seem to be doing anything.

MEFLinRegAngle(Closes[1],60,14,3,9,3,false);

[tshirtdeal]

okay, that was one of my other questions... do I have to call each plot for the indicator or can I just call the entire indicator up?

any tips to getting this to plot are greatly appreciated

[NinjaTrader_RyanM1]

You have to set indicator plots to something if you're using this in your own indicator. You have to set for each plot you want to display. Use the name of your plot and Set it to that indicator value. The default is named Plot0 but you may have change it in the indicator wizard.

Plot0.Set(MEFLinRegAngle(Closes[1],60,14,3,9,3,false)[0]);

Hey, well I get a plot now, it gives the correct value for the last bar but it does not look correct past the first bar and I cannot change the color of the line plot... any ideas?

[tshirtdeal]

Okay, it looks perfect on a 2 minute chart but totally different on the 5 minute (primary) chart when I add it,

[tshirtdeal]

okay, on the primary 5 minute chart it is caculating the values but only to the 5 minute bars, the value plot is not creating a "bar plot" for each 2 minute candle coming through.... any ideas how to fix that so it looks correct?

[NinjaTrader_RyanM1]

From your description, it sounds like it's working correctly. The values will by synced to that 5 minute bar, so there no 2min data that would take place "inbetween" them. If you aren't sure how it should look, try a simple example with SMA plotted on a secondary series. If you have any further concerns post a screenshot of this simple implementation.
