[amibroker] Re: How to select current bar?

["jnz88" <jnz88@xxxxxxxxx>]

I want to find out the second (or third ...) highest price within the
last 3 days in a 5-min intraday internal

prev = ref(C, -1);

lastbar = SelectedValue( BarIndex() );
period = 12 * 6.5 * 3;  // 3 days 5-min internal

firstHigh = HHV( prev, period );

// mark the first highest price to -1, so that can find the second highest
prev = IIf( BarIndex() == (lastbar - HHVBars(prev, period)), -1, prev );

secondHigh = HHV( prev, period );

Note: SelectedValue() only return the very last bar index in the time
range which is specified in the AA's Explore windows; But for the
other bars other than the last bar in the time range, it does not work

thanks,
