I have a code

 

Code

_SECTION_BEGIN("Test"); SetChartOptions(0,chartShowArrows|chartShowDates); _N(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", colorDefault ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() ); Buy = Cross(MA(C, 5), MA(C, 20)); Short = Cross(MA(C, 20), MA(C, 5)) OR C<O; Sell = short; cover = buy; PlotShapes(shapeUpArrow*Buy, colorBlue, 0, low); PlotShapes(shapeDownArrow*Short, colorPink, 0, high); dist = -12; fnt = "Arial"; fntsize = 8; txtdist = 25 - dist; bi = Barindex(); fvb = FirstVisiblevalue( bi ); lvb = LastVisiblevalue( bi ); for( i = fvb; i <= lvb; i++ ) { // iterate through visible chart area only if( Buy[i] ) PlotTextSetFont( StrFormat( "B@\n%g", BuyPrice[ i ] ), fnt, fntsize, i, L[ i ], colorBlue, colorDefault, -txtdist + fntsize ); if( Short[i] ) PlotTextSetFont( StrFormat( "Sh@\n%g", ShortPrice[ i ] ), fnt, fntsize, i, H[ i ], colorYellow, colorDefault, txtdist); } _SECTION_END();

I am using this in 1 minute candle. What I notice is that, depends on market movement, within same candle, it initially places buy signal and disappears depends on market movement and, after a while, it places short signal and again that disappears too.

May I know how to place these orders only once in a candle and it should not disappear once its placed.

Do you trade for the first time?

Of course signals disappear in real-time on last bar if calculation includes last bar since MA calculation depends on close price and in your case current price can move above or below of MA while bar is not finished yet. So signals may appear or disappear on very last bar.

If you don't want to calculate on current bar but on previous one(s) then use Ref() to check signal for true/false on previous bar(s).

 

Code

... Buy = Cross(MA(C, 5), MA(C, 20)); Short = Cross(MA(C, 20), MA(C, 5)) OR C<O; Buy = Ref( Buy, -1 ); Short = Ref( Short, -1 ); ...

Or if in realtime you only want to do execute calculation on current bar when it is finished then i.e. use status( "lastbarend" )


Here is a sample function by Janeczko

 

Code

function NewBarJustArrived() { // sample function by T. Janeczko vname = "lbe" + GetChartID(); prev = Nz( StaticVarGet( vname ) ); curr = Status( "lastbarend" ); StaticVarSet( vname, curr ); return curr != prev; }

Example?

Perhaps like this one

 

Code

function NewBarJustArrived() { // sample function by T. Janeczko vname = "lbe" + GetChartID(); prev = Nz( StaticVarGet( vname ) ); curr = Status( "lastbarend" ); StaticVarSet( vname, curr ); return curr != prev; } shortcond = Cross( MA( C, 20 ), MA( C, 5 ) ) OR C < O; buycond = Cross( MA( C, 5 ), MA( C, 20 ) ); if( NewBarJustArrived() ) { StaticVarSet( "Buycond", buycond, persist = false ); StaticVarSet( "Shortcond", shortcond, persist ); } Buy = StaticVarGet( "Buycond" ); Short = StaticVarGet( "Shortcond" ); Sell = Short; Cover = Buy; //Buy = ExRem( Buy, Sell ); //Sell = ExRem( Sell, Buy ); //Short = ExRem( Short, Cover ); //Cover = ExRem( Cover, Short ); SetChartOptions( 0, chartShowArrows | chartShowDates ); _N( 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", colorDefault ), styleNoTitle | ParamStyle( "Style" ) | GetPriceStyle() ); PlotShapes( IIf( Buy, shapeUpArrow, shapeNone ), colorBlue, 0, low ); PlotShapes( IIf( Short, shapeDownArrow, shapeNone ), colorPink, 0, high ); dist = -12; fnt = "Arial"; fntsize = 8; txtdist = 25 - dist; bi = Barindex(); fvb = FirstVisiblevalue( bi ); lvb = LastVisiblevalue( bi ); for( i = fvb; i <= lvb; i++ ) { // iterate through visible chart area only if( Buy[i] ) PlotTextSetFont( StrFormat( "B@\n%g", BuyPrice[ i ] ), fnt, fntsize, i, L[ i ], colorBlue, colorDefault, -txtdist + fntsize ); if( Short[i] ) PlotTextSetFont( StrFormat( "Sh@\n%g", ShortPrice[ i ] ), fnt, fntsize, i, H[ i ], colorYellow, colorDefault, txtdist); }

Or whatever ...

_SECTION_BEGIN("Test");

// Try this I use Barindex for wait the end of the last bar for trigger the signal

SetChartOptions(0,chartShowArrows|chartShowDates);
_N(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", colorDefault ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() );

Buy = Cross(MA(C, 5), MA(C, 20)) & BarIndex() < lastvalue( barindex() );
Short = ( Cross(MA(C, 20), MA(C, 5)) OR C<O ) & BarIndex() < lastvalue( barindex() )

Sell = short;
cover = buy;
PlotShapes(shapeUpArrow*Buy, colorBlue, 0, low);
PlotShapes(shapeDownArrow*Short, colorPink, 0, high);


dist = -12;
fnt = "Arial";
fntsize = 8;
txtdist = 25 - dist;
bi = Barindex();
fvb = FirstVisiblevalue( bi );
lvb = LastVisiblevalue( bi );
for( i = fvb; i <= lvb; i++ ) { // iterate through visible chart area only
if( Buy[i] )
PlotTextSetFont( StrFormat( "B@\n%g", BuyPrice[ i ] ), fnt, fntsize, i, L[ i ], colorBlue, colorDefault, -txtdist + fntsize );
if( Short[i] )
PlotTextSetFont( StrFormat( "Sh@\n%g", ShortPrice[ i ] ), fnt, fntsize, i, H[ i ], colorYellow, colorDefault, txtdist);
}
