KelvinHand,
i got the solution from another forum.
here is the code
// Note that if you get a sell within the reject period of the Buy
// it will be missed the first time. To fix this you have to modify
// the SayNotTooOften function.
function SayNotTooOften( text, Minperiod )
{
elapsed = GetPerformanceCounter() / 1000;
Lastelapsed = Nz( StaticVarGet( "lastsaytime" ) );
if ( elapsed - Lastelapsed > Minperiod )
{
StaticVarSet( "lastsaytime", elapsed );
Say( text );
}
}
// system source unknown…
Buy = Cross( MA( C, 13 ), MA( C, 15 ) );
Sell = Cross( MA( C, 15 ), MA( C, 13 ) );
Plot( MA( C, 13 ), "Fast 13 Periods MA", 2, 1 ); // White
Plot( MA( C, 15 ), "Slow 15 Periods MA", 4, 1 ); // Red
Plot( C, "", 1, styleCandle );
ManualBuy = ParamTrigger( "Manual Buy", "NOW" );
LastBuy = LastValue( Buy ) OR MAnualBuy;
if ( LastBuy )
SayNotTooOften( "Buy", 5 ); // Will not repeat voice output faster than once in 5-seconds
ManualSell = ParamTrigger( "Manual Sell", "NOW" );
LastSell = LastValue( Sell ) OR MAnualSell;
if ( LastSell )
SayNotTooOften( "Sell", 5 );
