Using indicator values

[traderT]

How would I go about assigning indicator plot values to a variable in a strategy? Currently I have an indicator that provides/plots an entry level. However the actual entry will only occur when that level is pierced, which normally happens a few bars after the plot.

So what I am asking is how I can store a value derived from an indicator in a strategy and once price breaks that value, a trade is entered.

As you can see in the picture, the indicator fires at 18:15, however, the buy zone (between the blue dots) is only pierced at 18:30.

I have tried using the examples for using an indicator's plots in a strategy and these do not work as I think that it has to occur on the same bar, which this is not.

Any ideas would be most helpful.

storeValue = myIndicator()[0];

Then you can do something like:

if (Close[0] >= storeValue)
     EnterLong();

or any other logic you may want to use.

Much appreciated

Thanks for the quick response, will give it a go once the markets close. Thx again.

Taking this a step further

Where would I put my variable from the indicator in the code that you pprovided ...

storeValue = myIndicator()[0];

Would it be ...

storeValue = GartleyRobotBull(BullDa)[0];

where GartleyRobotBull is the indicator and BullDa is the variable within the indicator that contains the value that I need?

traderT,

You need to first create the storeValue variable as a double in the Variables region of your code.

private double storeValue = 0;

Then you would use the code inside the OnBarUpdate() method. I do not know how your indicator works and how to access the particular variables for your indicator. I suggest you ask the original author of it.

The original author is useless

I am the orginal author ;-)

I understand that storeValue would need to be defined.

Within my indicator I have the following line...

privatedouble BullDa(){return (BullCa() + (1.27 * (BullB() - BullCa())));}

So, in my strategy, I want to set storeValue = myIndicator.BullDa

And then have ...

if (Low[0] <= storeValue)
EnterLong();

What I need to know is the syntax for myIndicator.BullDa if it is possible, or, if not, then what type of syntax would I need.

I have only been doing c# for a couple of months so I am still fudging my way through stuff and have managed to write a few indicators (You and the team have helped me quite a bit with the indicators that I wrote (Gartley and deMark indicators), but am now want to incorporate them into strategies, which I have not done as yet, hence the dumb questions ( I promise to make them more complicated as I learn more ;-)

You need to expose your indicator variable then. Please see this reference sample: http://www.ninjatrader-support2.com/...ead.php?t=4991

So something like this wouldn't work ...

if (GartleyRobotBull(5, 2, 65).BullDa[0]) > 0
{
(storeValue = (GartleyRobotBull(5, 2, 65).BullDa[0]))
}

Am having a look at the sample stuff now

[NinjaTrader_JoshP]

if (GartleyRobotBull(5, 2, 65).BullDa[0]) > 0
{
(storeValue = (GartleyRobotBull(5, 2, 65).BullDa[0]))
}

Am having a look at the sample stuff now

Yea, that wouldn't work because you closed the if-statement too early. You need to watch your parenthesis placement.

[traderT]

So what do I need to change to make this work?

if (GartleyRobotBull(5, 2, 65).BullDa[0]) > 0
{
(storeValue = (GartleyRobotBull(5, 2, 65).BullDa[0]))
}

[NinjaTrader_JoshP]

if (condition[SIZE=4][B][COLOR=Red])[/COLOR][/B][/SIZE]
{
   // code[SIZE=5][COLOR=Red];[/COLOR][/SIZE]
}

Lines need to end with ;
This is C# programming. I suggest you go to MSDN or google some resources for a starters guide to C# programming.

[traderT]

if ((GartleyRobotBull(5, 2, 65).BullDa[0]) > 0)
{
storeValue = GartleyRobotBull(5, 2, 65).BullDa[0];
}

Sorry, I figured that out, however (hopefully last question), now I get a protection level error. Do I have to declare BullDa as a public variable in my indicator?

Please see the reference sample for how to expose the variable via a public property.
