SMA status linked to other indicator

[jmsUK]

Good morning, I have been searching for threads to help with an issue but so far in vain.
I would like to be able to code the following: I have 3 SMAs and I want the software to be able to link, for example, the situation when any ONE of them is UP, to another indicator.
I also want to add another condition that the difference between 2 chosen SMAs should not be greater than a specified number.
Would be grateful for some help in this direction please.
TIA

Hello jmsUK,
Thanks for your note.

You can use the Rising function to check if any one of the SMA is UP or not.

if (Rising(SMA(14)) || Rising(SMA(34)) || Rising(SMA(50)))
{
	//do something
}

You can use the Math.Min function to make sure the difference between 2 SMA is not greater than a certain number. A sample code will be like.

double smaDiff = Math.Min(15, Math.Abs(SMA(14)[0] - SMA(34)[0]));

Have you sent a email to us in this context. If so then we would request you to use one channel only.

Joydeep, thank you very much for prompt reply. I will work with you suggestions and see how I get on

I am working through the ideas you gave me yesterday, but another issue has arisen in the meantime:
I am attempting to add a second time-frame (a tick chart) to the existing tick chart but am getting nothing. Is it possible to reference 2 tick charts (and no minute charts) in same strategy please?
Thanks

Hello jmsUK,
Yes, you can create multi-series strategies. Please refer to our help guide to know more aboit it.

http://www.ninjatrader.com/support/helpGuides/nt7/index.html?multi_time_frame__instruments.htm

You can also refer to the sample code which comes native with NinjaTrader.

• In Control Center menu bar goto Tools>Edit NinjaScirpt>Strategies...
• In the Strategies dialog please refer to the SampleMultiTimeframe and Sample MultiInstrument strategies.

You may also refer to this sample code

Good morning, I am still stuck at what appears to be a basic concept in terms of adding Bars,

I am trying to write a script to trade on a tick chart when 3 criteria occur together-
2 conditions on the tick chart involving Stocastic and bollinger band AND 1 condition on a higher time frame chart.

There appears to be a contradiction in the method for adding bars between the link:
http://www.ninjatrader.com/support/h...nstruments.htm / Adding Additional Bars Object to NinjaScript,
where a 3 min chart higher time frame) is added to a 1 minute (lower time frame)
and
the SampleIntrabarBacktest where on Initialise it is stated:
/* Add a secondary bar series.
Very Important: This secondary bar series needs to be smaller than the primary bar series.

I would prefer to load the strategy into the tick chart
I would be very grateful if you could clarify this for me.
Many thanks
Jeremy Stuart

Hello Jeremy,
Since the SampleIntrabarBacktest strategy backtests the strategy intrabar, a higher granularity secondary timeframe is needed (for example if primary data series is 5 minute then the secondary data series must be below 5 minute, say a one minute bar series). It is specific to the SampleIntrabarBacktest strategy only and not a general rule.

[jmsUK]

Thank you for that information and I will work with that.
Can you please answer this question specifically? Can NinjaTrader combine a 5 minute time frame with a tick chart. I have seen examples of 15, 5, 3 and 1 minute but does it work with tick charts and minute charts combined.
Thanks again for your support

Hello Jeremy,
Yes, you can add a minute and a tick bar (or any other period type) as additional bar series in a NinjaScript code.

[jmsUK]

Ok Thanks for that. This isn't easy!

[jmsUK]

I have used the code you gave me and come up with this combination, and it compiles but doesn't do what it should:
// Condition set 1 for buying
if (Stochastics(5, 14, 3).K[0] < 15
&& Low[0] < Bollinger(2, 14).Lower[0]
&& Rising(SMA(BarsArray[1], 10)) || Rising(SMA(BarsArray[1], 25))
&& ToTime(Time[0]) > ToTime(07, 00, 0)
&& ToTime(Time[0]) < ToTime(20, 50, 0))
{
I suspect my syntax is incorrect. Adding the reference to the 5 minute chart just does not work. Without the reference to the 5 min, it behaves as I want
Could you please guide me on this.
Many thanks as always for support

Hello Jeremy,
To assist you further can you please send a toy NinjaScript code* replicating the behavior to support[AT]ninjatrader[DOT]com

Please append Attn:Joydeep in the subject line of the email and give a reference of this thread in the body of the email.

I look forward to assisting you further.

*The "toy" just means something that is a stripped down version that isn't necessarily the whole logic. It makes things easier to rout out.

Thank you I am emailing
