// 6/4/2006 Fixed bugs and added exit on fresh cross option
//
// Added use of TakeProfit of 0
//
// Modified for trade on open of closed candle
//
// Added Trades in this symbol and MagicNumber check
// to allow trades on different currencies at same time
//
//
//
// Modified by Derk Wehler as follows:
// -----------------------------------
// 7/19/2006 Reformatted code, added comments
//
// Added HandleTrailingStop() function and changed start()
// function to use it.
//
// Added use of OrderReliable library
//
// Added extern TrailingStopType (which should always be
// set to either 1 or 2), for use with new HandleTrailingStop()
//
// 7/23/2006 Added UsePrevClose parameter, and usage in FreshCross()
