[amibroker] CBT and Nbar

["tipequity" <l3456@xxxxxxxxxx>]

The following CBT code is supposed to sell a long position after nth 
bar if I don't have a buy signal on the nth bar. The logic for the 
code is as follows:

1. loop thru open position list
2. if a positions has been open for nbar then check the buy list 
3. if the symbols exits in the buy list do nothing else sell the 
position.

For some reason that I can not figure out, the new function 
FindSignal always return a null value. Can anybody provide some 
insight or an alternative solution? TIA


for ( pos = bo.GetFirstOpenPos(); pos; pos = bo.GetNextOpenPos() )
{
	if ( pos.BarsInTrade >= Nbar ) 
	{
		_TRACE("i= " + i + " Date: " + dtstr + " Symbol: :" + 
pos.Symbol + " BarsinTrade: " +  pos.BarsInTrade + " Max Holding 
Period");
		if ( Sig = bo.FindSignal( i, pos.Symbol, 1 ) )
		{
			// ignore sell signal if we also have a buy 
signal
			_TRACE("i= " + i + " Date: " + dtstr + " 
Symbol: :" + pos.Symbol + " BarsinTrade: " +  pos.BarsInTrade + " 
ignore sell signal, we have Buy Signal, don't sell: " + sig);
		}
		else 
		{
			NextDayOprice = pos.getprice(i,"O");
			bo.ExitTrade( i, pos.symbol, NextDayOprice, 
5);
			_TRACE("i= " + i + " Date: " + dtstr + " 
Symbol: :" + pos.Symbol + " BarsinTrade: " +  pos.BarsInTrade + " We 
DONT have Buy Signal: " + sig );
		}
	}
}
