Re: [amibroker] Help with buy formula

[<professor@xxxxxxxxxxxxxx>]

I have included the chart with 3/14 lined to show the date in question.
The barssince was included in the cond6 so that did not cause the problem.


Thanks,
'Tom

  Place your increase statement above your condition statements.

  I loaded this formula and it gave me an error message.  "condition 10=c<increase AND Ref(c,-1)>ref increase. Message was variable 'increase' used without having been initialized.  Can you help me out, Please.   Marshall

    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. 

    Thanks, 
    Tom
