  The solution for the question asking to create the first function for Xmavg_price is incorrect.

  It takes the variable x, however never uses it and instead just uses 5.

  For clarity this is the solution provided

  ”’

  Xmavg_price: {[X]

  whereClause: () ; //enlisting JPM to keep as a symbol and not interpreted as a variable

  byClause:enlist [sym]!enlistsym;

  returnClause:enlist[price_5]!enlist (mavg;5;price);

  ?[trade;whereClause;byClause;returnClause]

  }

  Xmavg_price 5

  ”’
