Change Calculation from OnBarClose to OnEachTick and still recognize bar is close

[bosajin]

Hi,

I have developed a strategy and using the following code to take a position and the Calculation is OnBarClose.

if(Close[0] > Open[0])
EnterLong();
else if(Close[0] < Open[0])
EnterShort();

Is there a way to change the Calculation to OnEachTick and have exact same functionality(I mean detect when bar is closed).

Hello bosajin,

Thanks for your post.

When using Calculate.OnBarClose your code is executed once when the currently forming bar closes. The just closed bar is referenced as [0], This means Close[0] would refer to the close price of the just-closed bar. The new currently forming bar is unknown to your script until the bar closes and the new closed bar becomes [0].

When using Calculate.OnEachTick, your code is operated on every incoming tick of the currently forming bar. This means that the currently forming bar is referenced as [0], the just-closed bar would be [1] (so you can see that the references shift). Close[0] in this case would represent the current right edge price of the currently forming bar.

You can use the system bool of Bars.IsFirstTickOfBar as a means to perform once per bar processing. for example:

if (Bars.IsFirstTickOfBar)
{
if(Close[1] > Open[1]) // Using [1] here because we are operating on the first tick of the new bar which would be [0]
EnterLong();
else if(Close[1] < Open[1])
EnterShort();
}

Here is a link to another example of coding to use both oneachtick and once per bar processing: https://ninjatrader.com/support/help...either_cal.htm

Thanks Paul for swift response .
1) How can I access to price of a bar before the just-closed bar?
2) is there any delay between when a bar is close and another bar is opened?(I would make sure the IsFirstTickOfBar is fully trustable to get same result as OnBarClose)

Hello bosajin,

Thanks for your reply.

The barsAgo value is in sequence, [0] is the current bar, [1] the bar before that, [2] the bar before that, etc. etc.

Calculate.OnEachTick is an event-driven process, in this case as a tick comes in, that is the event that drives the process.
