Drawing an Arrow

[Ark]

In the strategy Action window...under "parameters"...in the "Y" line...I need to insert the phrase ..... Low(0) + 1 * TickSize

Can someone help me out? Thank you

In the Y line select the ... button and then select Price. Select Low then in the Offset field type in 1.

Drawing Arrows

Thank you Josh. it works very well. Can you tell me ....when I start my strategy with the ema's the line's automatically come up. I'd like to be seeing only the arrows without the lines. Currently what I'm doing is changing the colors of the lines to white ( negating the appearance since my background is white ). However every time I change time frames thec hart resorts to the lins appearing.

Is there a way to save the changes so that when I start my strategy the lines do not appear?
Happy trades ! Ark 1

How about trying to set the color to "Transparent" instead of white?

Hi Ray,
Again...I can't thank you enough for your support.
I've used either 'white'...or...transparent...it doesn't matter. They both do the job. My problem is the following. I'll go through my steps so that you can point out my mistakes.

1) after I've connected and my charts are up and running I must then right click on the chart and go through the process of starting up my strategy ( if there's a way around this please tell me...in other words...if I can open my charts> connect> and have my strategy start by default ...) that would be good.

2) when my strategy starts my charts, by default, display the arrows ( indicating the EMA crosses ) but in addition they also display the 'lines' ( orange colored by default ) for the EMA's.

3) I must then go to the indicators window and go through the process of making all of the 'ema lines' transparent so that the only thing that is visible on the chart are the arrows.

The big problem is that every time I change timeframes or instruments...or...open up the strategy...the ema lines appear again and I must go through the same steps to make them transparent.

Is there a method for accessing the 'orange ema lines' so that I can permanently make them transparent for my strategy? As I was going through the steps to creating my strategy I had the option of choosing the color for my arrows...but..the ema's give me no such option.

Got it.

1) This is the current approach, we will improve this with NT7 next year

You can do what you wish however, it can only be done programatically, not using the wizard. Here is a tip that shows you how this can be done.

Hi Ray,
I'm almost there.
Josh states: To customize plot colors:
Code:

EMA(13).Plots[0].Pen.Color = Color.Blue; // Plots the EMA as a blue line

Ok...here's my strategy....can you please tell me where I am to insert this code?

Here is an example:

Add(EMA(Fast));
Add(EMA(Slow));
EMA(Fast).Plots[0].Pen.Color = Color.Blue;
EMA(Slow).Plots[0].Pen.Color = Color.Red;

Now...looking at Josh's post he's also included ...

// Plots the EMA as a blue line

This line doesn't appear anywhere in my strategy.

Just to be clear, you never want to plot these indicators in your chart? If yes, just don't Add() them. Add() only adds them for plotting on the chart, nothing else.
