Want to create an indicator and have no idea where to start?

The 7th variable is the color of the bars, I may have to actually create inside the original indicator?

Got it!

This one wasn't the same. So I created a int DataSeries in the original indicator.

Then I could access it. But initially, this only changes the Data series when the color changed. So it wasn't a populated data series for every bar... if that makes sense?

So my DataSeries was all zeros, and +1 when up, and -1 when down. The zeroes weren't any good in there, so I added an IF statement:

Code

if (ERG_Trade().Ltsx[0] == 0) 
{
ERG_Trade().Ltsx[0] = ERG_Trade().Ltsx[1];
}

"Ltsx" is my data series created in the original. So now, after getting the data series, I check for 0, and if it is equal to 0, then fill it in with the previous bar's color bar value.

And here is a pic, it is tracking the change of the color bars. So I've got all 7 variables I need, now on to phase II for real this time!

............now on to phase II for real this time!

Woot!!!

I'm adding these trade definitions in a really clumsy way at the moment, but they are there, which is exciting. Take a look at the pic, you see 3 green arrows where possible trades are. I have a ton more scenarios to add in manually, but it's on the right track for now.

Oh, Woot!!

Hi Forrestang,

If your ProfTest Code still had this:

.........you ought to add this [CODE*TickSize][/CODE] so it will look like this:

..........as dataseries so that you can reference the prior bar's state. There are ways to use loops to emulate a dataseries (which is over my head). Otherwise, need to find otherways to draw arrows for only when the condition changes (if that's what you prefer to see rather than several continuous bars with the arrow below.

Keep up the good work.

Made your adjustment on the arrows, thanks!

I've got a clumsy way to draw the arrows only on the bar when it switches.

Having a problem.

Here is a pic of my indicator, and the code associated with my clumsy way of painting arrows. I have a lot of specific scenarios I want to set up, so I want to paint the scenario(1a_a, 1a_b, 1a_c... etc) along with the chart marker.

Here, all 3 of these green arrows on my chart should have the label "1a_a" under their prices like the one arrow does. I dont know how to use the "Draw" feature obviously.

How should this be set so the text will be drawn just like each arrow?

Here is the code snippet if it's hard to see:

Code

if(ERG_Trade().Ltsx[0] == 1 && ERG_Str1().HISTSlope[0] == 1 && ERG_Trade().HIST[0] >= 10 )
	{
	   if(ERG_Trade().HISTSlope[1] == 1 && ERG_Trade().HISTSlope[2] == 1 && ERG_Trade().HISTSlope[3] == -1)
		{	
		DrawArrowUp("arrow"+CurrentBar.ToString(), true, Time[0], Low[0]-12*TickSize, Color.Green);
		DrawText("text"+CurrentBar.ToString(), Open.ToString(), 0, Low[0]-30*TickSize, Color.Black);
		DrawText("text","1a_a", 0, Low[0]-38*TickSize, Color.Black);
		}
	}

Initially i thought it was because those DrawText objects with the same tag. But I checked by removing one of them, and still the same problem. So still not sure why it won't draw on ALL the arrows?

you are giving them identical tag 'text' in this case, try text1, text2, text3 instead.

I tried that, still seems to not print.

		DrawText("text1"+CurrentBar ,"1a_a", 0, Low[0]-38*TickSize, Color.Black);

Try this......

Yep! Thanks, that did it!

Got the logic done and it's doing what I want.

Is there a simple way to add a closing arrow to this? Does NT have some function built in so that once my green/red arrow prints to show my entry, I can plot an exit AFTER that entry arrow?

Asking as eventually I'll want to kick this out to a strategy.
