止盈止损

      If(data1.close[1] < data1.close[2] And MarketPosition == 1 And BarsSinceEntry >= 1 And data2.close[1] < data2.close[2] )

  {

Sell(0, data2.Open);

      }

      If(data1.close[1] > data1.close[2] And MarketPosition == -1 And BarsSinceEntry >= 1 And data2.close[1] > data2.close[2] )

  {

BuyToCover(0, data2.Open);

      }
