Zulutrade SMA EA

I want the expert to analyze two Simple Moving Average indicators (SMA1 and SMA2) (1) If Bid_Price is greater than SMA1 and the closing price of the last closed candle is less than SMA1, then the expert must first Close Sell_Position (if any exist) and then Open Buy_Position (if none exist already). (2) If Bid_Price is less than SMA2 and the closing price of the last closed candle is more than SMA2, then the expert must first Close Buy_Position (if any exist) and then Open_Sell Position (if none exist already) (3) Attach Stop_Loss Order to all Positions (4) If possible – allow for choice/ selection whether the expert to do Buy_Only, Sell_Only or both Buy&Sell
