Hi,
It's not that surprising that you would not get any signals. Your buy/sell criteria are very rigid. The Cross of the MACD would have to happen on exactly the dates that you specified, else your criteria would not be met. Also, I can't tell whether you've used a zero or the letter 'O' for the second argument to Cross. On my test symbol, using zero I get signals, using the letter 'O' (i.e. Open) I do not.
To help with debugging, use the following code. If you do not see a vertical green bar line up over top of a green square along the base, then your buy signal did not occur on a valid buy date. Likewise for selling, if a vertical red bar does not line up over top of a red square, then your sell signal did not line up over a valid sell date.
Dates = DateNum();
MyBuySignal = Cross( MACD(), 0 );
ValidBuyDates = Dates == 1030404;
Buy = MyBuySignal AND ValidBuyDates;
MySellSignal = Cross( 0, MACD());
ValidSellDates = Dates == 1041105;
Sell = MySellSignal AND ValidSellDates;
DateColors = IIF(ValidBuyDates, colorGreen, IIF(ValidSellDates, colorRed, colorLightGrey));
Plot(1, "", DateColors, styleArea | styleOwnScale | styleNoLabel);
Plot(MyBuySignal, "Buy Signal", colorGreen, styleHistogram, styleOwnScale);
Plot(MySellSignal, "Sell Signal", colorRed, styleHistogram, styleOwnScale);
Title = NumToStr(DateTime(), formatDateTime) + ", " + EncodeColor(colorGreen) + "Buy Signal: " + MyBuySignal + ", " + EncodeColor(colorRed) + " Sell Signal: " + MySellSignal;

There was one trade opened on the beginning 07/04/03 and closed at the end 08/11/04. No other buy/sell signals triggered during that date range. This is the arrangement example. Thanks so much anyway. :)
