1 strategy with 3 long position

Hola,

i'm trying to execute 3 buys with diferent conditions:

protected override void OnBarUpdate()
{
// Condition set 1
if (High[NumBarras] >= GetCurrentAsk() + DistCompra1)
{
EnterLong(QtyOrden, "Compra1");
}

// Condition set 2
if (High[NumBarras] >= GetCurrentAsk() + DistCompra2)
{
EnterLong(QtyOrden, "Compra2");
}

// Condition set 3
if (High[NumBarras] >= GetCurrentAsk() + DistCompra3)
{
EnterLong(QtyOrden, "Compra3");
}
}


But only works de first Buy. How could i do it?
