Buy/Sell Arrows at intersection of plot of two Series !!

Satish · Post by **Satish** » Mon Apr 11, 2005 1:35 pm

I need to plot buy/sell signal (green/red graphical arrows) for stocks related data on my chart. Is this feasible and how could one do that ?

Will appreciate suggestions/advice/code stubs. Thanks !!

Hi Satish,

I don't understand exactly what you want to achieve, but you might be interested in using ArrowSeries.

Hi Narcis,

I should have explained the problem in detail in my first post. Anyway here are the precise details:-

1. Have two series Series1(TCandleseries) & Series2(TLineSeries). Series2 is 30 days EMA of the CloseValue of Series1. Logic for plotting siganls is as follows:-

a) Buy signal/green arrow when Series1(closevalue) crosses Series2( EMA 30) from below. Series1[close] of yesterday < Series2 value of yesterday & Series1[close] of today > Series2 value of today.

a) Sell signal/red arrow when Series1(closevalue) crosses Series2( EMA 30) from above. Series1[close] of yesterday > Series2 value of yesterday & Series1[close] of today < Series2 value of today.

I need the arrows to appear on the chart. Hope this clarifies the requirement.

Regards,

Satish

Hi Satish,

According to your description I'd use ArrowSeries as I suggested you previously.

You can get CandleSeries values for each date compare them with LineSeries and use TArrowSeries.AddArrow(Const X0, Y0, X1, Y1: Double; Const ALabel: String; AColor: TColor): Integer; to add each arrow in the direction and color you desire.

An alternative could be using 2 arrow series one for each direction/color.
