use vector bt to backtest the following strategy:

a simple 3 period MA.....The Simple Moving Average Strategy goes Long when the Close crosses above the SMAvg line and Short when the Close crosses below it
  1. Initial capital= 100
  2. Benchmark is buy and hold of index
  3. Default Trade price is next open
  4. no transaction costs
  5. incorporate high/lows as well for releavnt calculations (example drawdowns based on high to low)
