Re: [amibroker] Nested Function

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

You can have function definition inside other function definition,
but you can have it both declared at global level and call one from the other.

function Function2(iiPrice, iiMAType, iiMAPer)
{
switch (iiMAType)
{
case 1:
    xaMA = DEMA(iiPrice, iiMAPer);
    break;

}
}


function Function1(iPrice, iMAType, iMaxPerMA)
{
xMAType = StrToNum( StrLeft( iMAType, 1 ) );

  Function2( iPrice, xMAType, iMaxPerMA );

}
