Hi, I must post my discovery that Mytrack does not hold onto 1 min chart data for more than a month. (So i have learnt from the Sierra forum) All i wanted to do was backtest a strategy for DJI going back 2 years. And now i am told its not possible except one alternative being SC Magic .. !(either $60 or $45 p/3 mths) .. My .mnd file is only 708k for 1 months 1 min data. does anyone archive these on a monthly basis .? Does anyone know of any other way of backtesting for the dow with sierra ?
