Is there a ninjascript tutorial for newbies?

[zehua]

Hi folks,
I am new to automated trading in Ninja trader. Is there a ninjascript tutorial? I am a professional software developer and I write a lot of C# and C++ code everyday. So hopefully I can ramp up with ninjascript reasonably fast.

Old guy, no experience

zehua,

How did you find the NT tutorials? With your experience I'm curious to know if they helped.
I'm an old guy with no programming experience, but I can read English. And the grammatical errors in the explanations make an already difficult project even harder. It drives me nuts! Have these ever been updated?
I'm very analytical and detailed. There has got to be a way to make NTScript click. It feels like I'm close but can't make the connection between the code and what it's going to do. Are they leaving something out on purpose?
Following the indicator/strategy tutorials if fine, but there seems to be a step missing, or an explanation missing, that would make it clearer what the code will do. Is this because NT wants us to give up and hire them to make our custom indicators/strategies?
I'm going to keep trying but very frustrating! Somewhere between and !

A reply would be great! Thanks.

Thanks Paul. I'll take a look at all of this. Specifically, I am looking to make an indicator that will return a % change in the Market Analyzer. So far to date, I have not seen where one can write or modify a script for the Market Analyzer. Will I find it in this tutorials? Thanks once again!

Best regards,

Hello Dolfan,

Thanks for the clarity of your question.

Please note that we do have a forum section specifically for the Market Analyzer. Any further Market Analyzer questions should be placed there: http://www.ninjatrader.com/support/f...splay.php?f=18

Indicators can be added to the Market Analyzer, they do not have to be specifically written for the Market Analyzer. Here is a link to a thread of such a discussion http://www.ninjatrader.com/support/f...ad.php?t=73552

Changing Overlay Indicators into Up Down Arrows

Hi,

I am trying to change the bwAlligator indicator overlay to just appear in an arrow UP or Arrow Down when prices close above or below the overlays. I do not need the overlays to be present as my current chart template has various moving averages and it would be more cluttered.


Also I am trying to change my trading strategy into a indicator which gives a buy Up Arrow or Sell Down arrow (i do not want it to be an autotrader just an indicator). This is based on the bwAlligator combined with parabolic SAR, RSI and MACD crossovers. I have read the threads on copying the codes into an indicator but seem to generate all errors and I am not sure where to start. My code for this is as follows:

protected override void OnBarUpdate()
{
// Condition set 1
if (CrossAbove(Close, bwAlligator().Jaw, 1)
&& Close[0] > ParabolicSAR(0.01, 0.2, 0.01)[0]
&& MACD(5, 10, 3)[0] > MACD(5, 10, 3).Avg[0]
&& Close[0] > EMA(200)[0]
&& RSI(14, 3).Avg[0] > 50)
{
EnterLong(DefaultQuantity, "");
}

// Condition set 2
if (Close[0] < EMA(28)[0]
&& MACD(12, 26, 9)[0] < MACD(12, 26, 9).Avg[0])
{
ExitLong("", "");
}

// Condition set 3
if (CrossBelow(Close, bwAlligator().Jaw, 1)
&& Close[0] < ParabolicSAR(0.01, 0.2, 0.01)[0]
&& MACD(5, 10, 3)[0] < MACD(5, 10, 3).Avg[0]
&& Close[0] < EMA(200)[0]
&& RSI(14, 3).Avg[0] < 50)
{
EnterShort(DefaultQuantity, "");
}

// Condition set 4
if (Close[0] > EMA(50)[0]
&& MACD(12, 26, 9)[0] > MACD(12, 26, 9).Avg[0])
{
ExitShort("", "");
}
}

Much appreciated.

Thanks.

Hello dwwtan,

Thanks for your post.

What I recommend is that you use the indicator wizard (Tools>New Ninjascript> indicator) to create a Ninjascript file that will have all the structure needed for an indicator. After you have a new Ninjascript file, copy and paste your code into the OnBarUpdate() method. You will want to keep track of the "{" "}" as you must have matching pairs. You will need to remove all your entry and exits as these will not be recognized in an indicator script. You can replace these with whatever drawing object you wish (arrows, dots, squares, triangles). Here is a link to DrawArrowDown and DrawArrowUp:

One similar question, Paul, regarding another (vendor's- black box) indicator which is installed on my NT7 indicators list BUT it is not appeared in the "wizard" indicators list ! The question is this : iiin the above code line :
if (CrossAbove(Close, bwAlligator().Jaw, 1)
if I replace the "bwAlligator().Jaw" with the name of another ("black -box"/vendor's) indicator will the strategy code (or another similar strategy code) work ?
This problem is general : Can we write startegy codes using "black-boxes" (vendors') indicators ? and how can we insert such indicators in a strategy code to make this strategy working with these ("black-boxes") indicators?
Any tip ?
Please advice.
Thank you.

The simplest way is to contact the vendor and ask for information on what properties are exposed, and how to call the indicator itself. This is standard programming information, and will usually be given if requested. At least we always give any such requested information.

Often, however, if the meta data is not masked, Intelllisense will tell you most, if not all, of what you need/want to know.

Hello gplatis,

Thanks for your post.

I agree with member Koganam's thought to contact the vendor directly.
