Need Help - Buy Sell Arrows not coming in this code

[rbhapkar]

Dear Senior Members,
Requesting help to find what is wrong in my code...
I'm not getting the Buy / Sell Arrows on screen.
Here is the code:

_SECTION_BEGIN("Price");
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", colorBlack ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() );
_SECTION_END();

_SECTION_BEGIN("EMA");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );
_SECTION_END();

_SECTION_BEGIN("EMA1");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );
_SECTION_END();

_SECTION_BEGIN("EMA2");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );
_SECTION_END();

_SECTION_BEGIN("Volume");
Plot( Volume, _DEFAULT_NAME(), ParamColor("Color", colorBlueGrey ), ParamStyle( "Style", styleHistogram | styleOwnScale | styleThick, maskHistogram ), 2 );
_SECTION_END();

Cross_5_8_B=Cross(EMA(Close,5), EMA(Close,8));
Cross_8_13_B=Cross(EMA(Close,8), EMA(Close,13));
Cross_8_5_S=Cross(EMA(Close,8), EMA(Close,5));
Cross_13_8_S=Cross(EMA(Close,13), EMA(Close,8));


Buy = Close > Cross_5_8_B AND Cross_8_13_B;
Sell = Close < Cross_13_8_S and Cross_8_5_S;


Short = Sell;
Cover = Buy;

Buy = ExRem(Buy, Sell);
Sell = ExRem(Sell, Buy);

shape = Buy * shapeUpArrow + Sell * shapeDownArrow;
PlotShapes(shape, IIf(Buy, colorGreen, colorRed), 0, IIf(Buy, Low, High));

Try those.

PlotShapes( shapeUpArrow * Buy, colorBlue,0,L,-12);
PlotShapes( shapeDownArrow * Sell, colorRed,0,H,-12);

hi,
do you think that this line will be true for any day?
Buy = Close > Cross_5_8_B AND Cross_8_13_B;
Sell = Close < Cross_13_8_S and Cross_8_5_S;

Cross function gives an array of 1's or 0's
Close is the close price.

buy will be always true if close price is more than 1, so sell will be always false for (e.g. Reliance) .

Give the conditions specifically like.
I would like to buy when ema5_8 < ema _8_13 and close is more than the value when the cross took place (specify how many days in history should one look for cross) or something like that..

ashutosh
