[amibroker] How to find angle of interseciton

["murthysuresh" <money@xxxxxxxxxxxxxx>]

Hi,
My code is posted below

_SECTION_BEGIN("Elder_Channel");

Period = Param( "EMA Period", 9, 2, 100 );

//Co_Efficient = Param( "Co_Efficient", ATR(9),0.05, 5, .05 );
EMACalculated=EMA(Close,Period);

UpperChannel=EMACalculated+ATR(33);
LowerChannel=EMACalculated-ATR(33);

Plot(UpperChannel,"UpperChannel",colorRed,styleLine);
Plot(LowerChannel,"LowerChannel",colorWhite,styleLine);
Plot(EMACalculated,"EMA " + Period,colorGreen,styleLine);

SetChartOptions(0,chartShowArrows);
Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, 
Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( 
C, 1 ) ) );
Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle | 
ParamStyle("Style", styleCandle, maskPrice ) ); 
_SECTION_END();

_SECTION_BEGIN("EMA1");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 200, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", 
colorCycle ), ParamStyle("Style") ); 
_SECTION_END();

MY QUESTION:

How do i find the angle of intersection between 
Plot(LowerChannel,"LowerChannel",colorWhite,styleLine);
and 
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", 
colorCycle ), ParamStyle("Style") ); 

Thanks in advance.
