[amibroker] Re: Is there a faster way of writing this AFL?

["Bisto" <bistoman73@xxxxxxxxx>]

sometimes I use this but I never check if it's really useful

I mean: if I put inside the {} only plot or plotshape or title calls like


if ( Status( "action" ) == 1 )
{
    _N( Title = StrFormat( "{{NAME}} - " + FullName() + " -{{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) Vol "
                           + WriteVal( V, 1.0 ) + " " + " {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ) );
    Plot( C, "Close", colorBlack, styleNoTitle |
          LastValue( IIf( LastValue( L ) == LastValue( H ) AND LastValue( C ) == LastValue( O ), styleDots, styleCandle ) )/*GetPriceStyle()*/ );

    Plot ( MA( C, Veloce ) , "Veloce", colorRed, styleLine );

    Plot ( MA( C, Lenta ), "Lenta", colorBlack, styleDashed | styleLine );

}

I really speed up the backtest or AB, during a backtest, already ignores Plot and similar calls?

did you do a test?

Tomasz, are you reading?

it's sure that putting inside {} all the calculations needed for plot is useful, mu doubt if it is useful to do it also with functions that are used only for plotting pourposes

thanks
