It is just a simple test code, but the buy changes as explained.
Buy1 =  MACD(5,26) > Ref(MACD(5,26), -1);     // macd 1 is going up.
Buy2 = MACD(12,26) > Ref(MACD(12,26), -1);   // macd 2 is going up
Buy3 = StochK(14,3) > Ref(StochK(14.3), -1); 	
// Buy and Sell orders
Buy		= Buy1 AND Buy2 AND Buy3;

I just don't understand why 2 bars later that the buy signal changes. 
I get a buy arrow on my chart and the backtest will also change 2 
bars later and show a buy when it didn't show it before.
