Help me fix my simple Line @ Bid Price Indicator

[NinjaCustomer]

Hi,

I'm trying to make a simple indicator that will draw a horizontal line across the chart at the current Bid Price. No luck though, I do not see any line at all.

This is my first foray into NinjaScript coding, so I'm sure I'm just overlooking something "obvious". Any help appreciated, thanks.

This will never works since you are assuming that GetCurrentBid() will dynamically return the bid value for the plot. GetCurrentBid() only returns a value when its called so you are in fact setting the plot to a constant value of which since GetCurrentBid() may not return a value until after OnBarUpdate() is called...I don't recall.

What you will want to do is set the value of the Plot in the OnBarUpdate() method and run the indicator with CalculateOnBarClose = false. This will only update the bid line on a change in the last trade.

Hi Ray,

thanks... I tried using a Plot first but figured that is not what I need. A Plot will plot it like a regular price... i.e. squiggly... what I need is a horizontal line at the current price.

How do I do that?

You could try using DrawHorizontalLine()

You could try using DrawHorizontalLine()

after I draw it, how do I update it? DrawHorizontalLine() returns void according to compiler. How can I get the Horizontal Line object?

Use the same tag such as the line below. Thats the only thing you need in OnBarUpdate().

DrawHorizontalLine("BidPrice", GetCurrentBid(), Color.Blue)

cool thanks.. that worked..

one more question though... how do I publish the Color value of this line so that I can change it in the indicators dialog?

Hi NinjaCustomer,

Could you post the corrected code for this indicator?

Thanks...
