I've been using the select_by_pos for mode_history to assign the magic number from the most recently closed trade to a variable. This doesn't seem to work so I'm wondering if it's possible to select history by position (because the variable once initially set doesn't change) or if my code is wrong:

Code:
if OrderSelect(0, SELECT_BY_POS, MODE_HISTORY) then
    begin
      if (OrderMagicNumber <> tempOrder) then
      begin
        tempOrder:= OrderMagicNumber;


I try to incriment magic number when opening new orders so every order is different:
Code:
SendInstantOrder(Symbol, op_Buy, PositionSize, StopPrice, ProfitPrice, '', TempMagicNumber, OrderNumber);
        TempMagicNumber := TempMagicNumber + 1;


Once the code initially sets tempOrder the value of the variable doesn't change, any suggestions?

Well, but you always select 0 position in history, how can MagicNumber change there? At least try to go through all orders in history.
