[amibroker] Re: How To Plot Long And Short Stop Alternately On One Chart?

["Lesmond V" <ebsn247@xxxxxxxx>]

Thanks, Joseph. This basically solves my problem. I've just tried to
set colour to "Null" instead of the "background colour" but it looks
like "Null" is not allowed in this particular situation. Any comment
on this, anyone?

This code includes "Null" in the plot statement and it doesn't work
right:

LongSignal = C > ( LLV( L, 20 ) + 2 * ATR( 10 ) );
ShortSignal = C < ( HHV( H, 20 ) - 2 * ATR( 10 ) );
DynamicColour = IIf( LongSignal, colorLime, colorRed);

TrailingStopLong = HHV( C - 2 * ATR(10), 15 );
TrailingStopShort = LLV( C + 2 * ATR(10), 15 );

Plot( TrailingStopLong, "", IIf( LongSignal, 38, Null), 512 );
Plot( TrailingStopShort, "", IIf( ShortSignal, 53, Null), 512 );

Title = Name()+" \\c11"+Interval(format=2)+" "+Date()+"\\c-1 C="+C;
Plot( Close, "", DynamicColour, 64 );
SetChartOptions(0, chartShowDates);

/****/
The code below works OK. It uses "background colour" in the plot
statement instead of "Null" (for white background use "55" as is, for
black background  replace "55" with "16"):

LongSignal = C > ( LLV( L, 20 ) + 2 * ATR( 10 ) );
ShortSignal = C < ( HHV( H, 20 ) - 2 * ATR( 10 ) );
DynamicColour = IIf( LongSignal, colorLime, colorRed);

TrailingStopLong = HHV( C - 2 * ATR(10), 15 );
TrailingStopShort = LLV( C + 2 * ATR(10), 15 );

/* Iif(..., ..., white background: 55 / black background: 16) */
Plot( TrailingStopLong, "", IIf( LongSignal, 38, 55), 512 );
Plot( TrailingStopShort, "", IIf( ShortSignal, 53, 55), 512 );

Title = Name()+" \\c11"+Interval(format=2)+" "+Date()+"\\c-1 C="+C;
Plot( Close, "", DynamicColour, 64 );
SetChartOptions(0, chartShowDates);
