Draw Repeater only on current day

[YanisR]

Hello community,
I'm trying to edit the custom indicator "Repeater2.2" in a way that it only draws on the current day.
Basically i'd like to bypass the "Repeat Daily, Repeat Monday, etc..." in order to draw the line/rectangle only on the current day.
I use Tool type: Opening Range.

I tried to edit it by myself but i'm not familiar at all with ninjascript and i can't seem to find the solution.

If someone can point me on the right direction, it would be much appreciated!
Thanks.

Hello YanisR,

Welcome to the NinjaTrader forums!

Below I am providing a link to a support article with helpful resources on getting started with C# and NinjaScript.

You can also contact a professional NinjaScript Consultant who would be eager to create or modify this script at your request or assist you with your script. The NinjaTrader Ecosystem has affiliate contacts who provide educational as well as consulting services. Please let me know if you would like a list of affiliate consultants who would be happy to create this script or any others at your request or provide one on one educational services.


Are you seeing in the script where the line and rectangle are being drawn in the script?
Is this from Draw.Rectangle() in OnBarUpdate() or RenderTarget.DrawRectangle() in OnRender()?
What is the condition statement that the draw method call is in?

Hello Chelsea and thanks for the reply.
The code is:

[Draw.Line(this, label[i]+"Upper", false, Time[CurrentBar - beginBar[i]], startStopPrice[i,1], MySessionIterator.ActualSessionEnd, startStopPrice[i,1], brushColor[i], DashStyleHelper.Dot, 1);
Draw.Line(this, label[i]+"Lower", false, Time[CurrentBar - beginBar[i]], startStopPrice[i,2], MySessionIterator.ActualSessionEnd, startStopPrice[i,2], brushColor[i], DashStyleHelper.Dot, 1);

While waiting for the reply i've been doing some researches and discovered the "addDataSeries" and "BarsinProgress" to try to check if we are in the current day before drawing the line.

I've been trying editing the code made by @NinjaTrader_Kate here: https://forum.ninjatrader.com/forum/...98#post1170998 since it's easier to understand:

I added

AddDataSeries(BarsPeriodType.Day, 1);

and then below

if(BarsInProgress !=0)
{
if (Times[2][0] != Times[2][1])
{​

but it doesn't work.

Hello YanisR,

In the each of the conditions that call the draw methods, also require the bar date to be equal to today's date.

For example:
if(Times[1][0].TimeOfDay == SessionStart.TimeOfDay && Times[1][0].Date == Core.Globals.Now.Date)

Adding an additional series would not be necessary.

[YanisR]

Oh wow that's it!
It works great.

Thank you so much for the help, it was driving me crazy
