[amibroker] Help with buy formula

When I backtest my formula, all the buys and sells are shown 
correctly except one. I cannot figure out what is wrong. Here is the 
buy and sell code: 
//Buy Signals 

Condition1 = C > Dropline AND Ref(C,-1) < Ref(Dropline,-1); 
Cond1=StochK() - Ref(StochK(),-1) >1; 
Cond2=MACD() > Ref(MACD(),-1); 
Cond6=StochD()<25; 
Cond7=BarsSince(Cond6) <=7; 


//Sell Signals 

Condition10 = C < Increase AND Ref(C,-1) > Ref(Increase,-1); 
Cond11=StochK() - Ref(StochK(),-1) < 1; 
Cond12=MACD() < Ref(MACD(),-1); 
Cond16=StochD()>75; 
Cond17=BarsSince(Cond16) <=7; 

//Buy and Sell orders 

Buy = BarsSince(Condition1) <=5 AND Cond1 AND Cond7; 
Sell = BarsSince(Condition10) <=5 AND cond11 AND Cond17; 

//Short and Cover conditions 

Short = Sell; 
Cover=buy; 

Graham wrote the code for the Condition1 and Condition10. It plots an 
arrow on the graph so I know that it works. I have checked the 
stochastic and macd for the buy in question and these are the 
figures: 

3/10 Stok = 20.06 
3/13 Stok = 26.42 
3/14 Stok = 34.98 

3/13 Macd = -1.74 
3/14 Macd = -1.54 
3/14 Green up arrow 

The formula should have covered my short and placed a buy. 

It held my short and did not place a buy. 

Everything else is perfect except that one day. I have backtested 
from 9/2/05 and have 12 trades. 

Thanks, 
Tom
