thise are 3 ma crossing with adx 14
1)LWMA,price field- close, 21periods,skye blue colour
2)EMA,price field-LWMA(21),3periods,yellow colour,style dasshed
3)EMA ,price field-close,periods-50,blue colour ,style thick
4)adx 14
buy=1)ema cross lwma >ema(50) with adx bullish cross(+DI cross -DI) with adx above 20
sell=1)lwma cross ema3<ema(50) with adx bearish cross(-DI cross +DI) with adx above 20

Dear friend c.trader,
this code will show a green arrow on chart for the required buy condition and a red arrow for the required sell condition
here is the code

_SECTION_BEGIN( "Price1" );
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() );
_SECTION_END();

_SECTION_BEGIN( "lwma" );
function LWMA( P, per )
{
    s = 0;
    pa = 0;

    for( i = 0; i < per; i++ )
    {
        s = s + ( Ref( P, -i ) * ( per - i ) );
        pa = pa + ( per - i );
    }

    return ( s / pa );
}
