Mike, that is the winner. [:p] Thankyou so much. I wish you well and hope I can help out in some way.

However, if you include conditional logic to only accept signals during specific periods, then you can run the backtest over the a timeframe that includes all periods and the code will prevent trading except during allowed periods. e.g. Trade only during 2003 and 2005, vertical bars over green squares will be accepted, others will be ignored. Dates = DateNum(); ValidDates = (Dates >= 1030101 && Dates <= 1031231) || (Dates >= 1050101 && Dates <= 1051231); MyBuySignal = Cross( MACD(), 0 ); Buy = MyBuySignal AND ValidDates; MySellSignal = Cross( 0, MACD()); Sell = MySellSignal AND ValidDates; > DateColors = IIF(ValidDates, colorGreen, 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; Alternatively, have a look at BatMan in the Files section of this group and write a batch script to run your backtests over each of the desired periods.
