Double RSI stochastic adding position strategy (by Zhipengcfel)

Updates: Change strategy.entry to strategy.order function to place orders. Changed strategy.oca.reduce to strategy.oca.none group.
Results: The rewards are higher than strategy.entry with pyramiding parameter but the max drawdown goes higher too.
Next step: Try to reduce max drawdown with risk management.
