  2. 4108 means something completely different in MT5.

    4108

    ERR_INVALID_TICKET

    Invalid ticket

    Why did you post your MT4 question in the Root / MT5 General section instead of the MQL4 section, (bottom of the Root page?)

  3. if (OrderType()==OP_BUY &&mc1>mc2&&mc01<mc02 )
    You can not use any Trade Functions until you select an order.
  4. ris=OrderClose(ticket,lots,Bid,3,clrAqua);
    Obviously your ticket variable is bogus. Do you even check if the order has already been closed, or if you haven't opened one yet?

  5. Check your return codes for errors and report them.

  6. Use the debugger or print out your variables, including _LastError and find out why.
