Question on Add() method for indicators

[zehua]

I see the following code example, and I am wondering if it is adding the SMA to the primary time frame only, or it is adding to all time frames? Later in OnBarUpdate(), it is using SMA there as SMA(BarsArray[1], 5). I am wondering if in Initialize(), we don't Add() this indicator, then can we still use it in OnBarUpdate()?

protected override void Initialize()
{
// Add a 5 minute Bars object to the strategy
Add(PeriodType.Minute, 5);

// Add a 15 minute Bars object to the strategy
Add(PeriodType.Minute, 15);

// Note: Bars are added to the BarsArray and can be accessed via an index value
// E.G. BarsArray[1] ---> Accesses the 5 minute Bars object added above

// Add simple moving averages to the chart for display
// This only displays the SMA's for the primary Bars object on the chart
Add(SMA(5));
Add(SMA(50));

CalculateOnBarClose = true;
}

zehua,

Yes, if you don't add this indicator you can still use it later by calling it the normal way.

Please let me know if I may assist further.

[zehua]

I see. So Adding an indicator in Initialze() is just to make the chart look better, and easier for programmers to see in the chart whether the entries and exits are as expected?

zehua,

Yes, you are correct.

Please let me know if I may assist further.

on the same note... can you add an indicator from the initialize section from another time frame by adding an index value? i.e.
// Add 1597 Broadview Tick Chart
Add(PeriodType.Tick, 1597);

// Add the 9 WMA from the 1597 Tick Chart to your primary bars (4 Tick Range) chart.
Add(WMA(9)[1]);

Solomon,

Are you looking to access these indicators using a BarsInProgress filter or are you just wanting to add them to your chart?

This : Add(WMA(9)[1]); wouldn't work unfortunately, because the Add method for this override requires an indicator object, not the value at [1].

Are you wanting to add the WMA of this second data series to the chart?

[Solomon]

sorry, I didn't see your reply so fast!
Yes, I want to add them to my chart using (I have the calculateonbarclose = false) because I wanted a more frequent indicator on my 4 range chart from the 9WMA of the broader 1597 tick chart. Otherwise, it'd be all step ladder like. Thanks for your help btw

Solomon,

Is this an indicator or a strategy you are creating?

Also, please note its possible to add a EMA for example of a separate dataseries on 1 chart without coding at all.

[Solomon]

Oh yeah, I completely forgot about overlaying a chart. thanks for the reminder!

BTW, I'm creating a strategy on the 4 range chart comparing it to indicators on the 1597 tick chart. One of the conditions is WMA 9 rising from index [1] chart (the 1597 tick chart). All the other charts allow me to refer to index bars 1, except for that condition. is there a reason?

Thanks again

[Solomon]

ps, when I overlay the chart, the primary bars are no longer equidistant. Is there a way to make the primary bars spaced equidistantly and not the 1597? It seems it's setting the equidistance based on the 1597 tick chart, which I set to transparent...

[NinjaTrader_AdamP]

Solomon,

I am happy to assist.

Did you set the other data series to transparent color?

As far as your other question, could you possibly post a code example of what you tried and didnt work?

[Solomon]

This is a picture of the non equidistant bars when I try to use the transparent tick chart with the range chart. I understand both can't be aligned at the same time, but is there a way to make it align by the 4 tick range chart? Thanks

[Solomon]

&& Close[0] > WMA(9)[1]
&& Close[0] > SMA(200)[1] + 12 * TickSize
&& Close[0] > SMA(55)[1] + 12 * TickSize
&& SMA(200)[1] > SMA(55)[1]
&& Rising(WMA(9)) == true)
{
BackColor = Color.DarkGreen;
Alert("MyAlert0", Priority.High, "Check for Long!", @"C:\Program Files (x86)\NinjaTrader 7\sounds\Alert3.wav", 10, Color.DarkGreen, Color.White);
}

[Solomon]

From the conditions listed, I want the rising WMA9 to come from the 1597 Broadview chart. It appears the way I have it, it is using the primary bars of the barsarray. When I try adding it "&& Rising(WMA(9)[1])" an error pops up.

[Solomon]

I found the answer to my multitimeframe chart strategy. So don't worry about the rising WMA condition, and if you can't find how to keep the 4range chart equidistant with the 200SMA from the transparent 1597 chart overlayed, don't sweat it. I'll just have two charts open. The big one was the strategy, thanks!
