How Can I Program: Go Long on first bull candle after the event?

[bijan]

Hi Guys
I am trying to program that after the event (which I have already programmed) then go long on the close of the first bull candle (close > open). I thought it should be something like:
EnterLongLimit(Close [n]);
But I need to specify what n is: n=first bull candle after "event". So if my event is: Close [0] < Close [1] for example then it should be something like:
{
(Close [0] < Close [1]
&& Close [n] > Open [n]
n=any candle after 0)
}

EnterLongLimit(Close [n]);

I am not sure how this can be accomplished using the programming language of Ninja. So some guidelines would be appreciated, or the actual code.

Reading through some code I found that there is a statement : bullFound = true;
I am wondering if I can use this to accomplish what I am trying to do. If so please guide me in how and where this statement has to be entered to accomplish what I am trying to do.

Thankyou.

Hello,

There are a couple ways to handle this. I've put together a small example which takes use of your "bullFound" flag you can add.

                 #region Variables
		private bool bullFound = false;
		private double entryPrice = 0;
                 #endregion

		protected override void OnBarUpdate()
		{
			
			//checks for bull candle
			if(Close[0] > Open[0])
			{
				bullFound = true;
			}
			
			while(bullFound)
			{
				//stores close price of bull candle
				entryPrice = Close[0];
				//resets bullFound to be checked again on the next OnBarUpdate call
				bullFound = false;
			
			}
			
			//when condition is true...
			if(Close[0] < Close[1])
			{
				//...enter limit order at entry price from bullFound bool
				EnterLongLimit(entryPrice);
				
				//you may want to use some draw objects to visual on the chart that the entry was where you wanted it to be
				DrawDot("entryPrice"+CurrentBar, false, 0, entryPrice, Color.Blue);
			}
			
		}

If you're new to C# and NinjaScript, I'd suggest going through some of the basic tutorials we've developed to help you get started with some of these concepts:

Matthew thanks for the reply.

I am trying to change the sample code you wrote to what I am trying to code. I like to know where do I place this portion of your code, under what heading (for example under protected override void Initialize ( ):
#region Variables
private bool bullFound = false;
private double entryPrice = 0;
#endregion

Also for one of the things I am trying to do I need to find a bar that has a certain value of an indicator. So for example its time duration is of a certain length. How can I accomplish this. In other words how can I tell the program to "find" the bar that has this character?

Bijan,

There should be a Region variables section in your strategy.

I've attached a copy to help demonstrate.

Regarding your second task, there are a number of ways to accomplish this. Please have a look at our reference sample on Getting indicator values from a specified time
