OrderClose Issue + WeekDay Filter

[statstrader]

Dear MQL4 experts,

I am learning MQL4 and building my first expert advisor. I tried to learn as much as I can in the beginning but would need some help with my code

Trade Setup:
--------------

Open Buy Order on Fridays at market open, if the D1 Candle open of the previous day AND todays open are above the EMA (x).

The Order should be closed on Monday at D1 open.

I put in a couple of input variables as I need to adjust them for different instruments in the future.

Issue:

-------

In the journal of the stratefy tester I can see that the order is opened and closed again right away without taking care of the Weekday filter.

The price in the strategy tester window is not moving at all. I see only one order.

The journal says:

- unknown ticket #1 for order close function
- Order Close Error 4108

The Code:
-----------

#property strict

int MagicNumber=10000;
int MaxTrades=1;


// Global external variables
//--------------------------
enum dayOfWeek
  {
   Sunday,
   Monday,
   Tuesday,
   Wednesday,
   Thursday,
   Friday,
   Saturday,
  };

input dayOfWeek TradeOpenDay = Friday;    //TradeOpenDay of the week
input dayOfWeek TradeCloseDay = Monday;   //TradeCloseDay of the week
input int EMAperiod = 10;                 //EMA period
input double SL_ATR_Multi = 1.00;         //SL_ATR_Multiplikator
input double TP_ATR_Multi = 3.00;         //TP_ATR_Multiplikator
input double LotSize = 0.01;              //Lotsize Traded
input int MaxSlippage = 10;               //Maximum Slippage
