This is an incorrect expression which could be open to misinterpretation Cond1=StochK() - Ref(StochK(),-1) >1; What it is saying is StochK() - (Ref(StochK(),-1) >1) which breaks down to either StochK() - 1 or StochK() -0 If StochK()==1 then it would return false, otherwise true Try this, although I do not quite understand the logic of this condition Cond1= ( StochK() - Ref(StochK(),-1) ) >1; which means current bar StochK is more than 1 unit above previous value Are you wanting the StochK to be rising? Cond1= StochK() > Ref(StochK(),-1);

Marshall ----- Original Message ----- *From:* professor77747 <[EMAIL PROTECTED]> *To:* [email protected] *Sent:* Sunday, December 10, 2006 3:23 PM *Subject:* [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.
