Monday Dip EA- Index Mean Reversion D1 - MetaTrader 5 için uzman

The Expert Advisor trades directly on whichever symbol chart it is attached to (no hardcoded symbols). It executes a maximum of one trade per week and all strategy decisions are calculated exclusively using Daily (D1) closed candle data based on server time.

⚡ Core Rules

• Rule 1 — Entry: On Monday close, the closing price is compared with the previous session's close (usually Friday). A long position is triggered only if Monday’s close is strictly lower than the prior trading day’s close. This check occurs only once per week.
• Rule 2 — Exit: The open position is automatically closed at Wednesday's daily close (executed at the first tick of the next daily session), regardless of profit or loss. If Wednesday close is missed, any subsequent daily close (Thursday, Friday, or weekend close) will trigger the exit.
• Rule 3 — Stop Loss & Safety: A percentage-based Stop Loss ( InpStopLossPercent ) is applied upon entry, respecting the broker's minimum stop distance ( SYMBOL_TRADE_STOPS_LEVEL ). If 5 consecutive attempts to apply or modify the Stop Loss fail, the EA attempts an immediate market close to ensure capital safety. Note: There is no Take Profit target—exits are entirely time- and stop-based.

🛡️ Optional Entry Filters

Both filters are optional toggles that can only restrict entries further (they will never create entries on their own or loosen Rule 1):

• Internal Bar Strength (IBS) Filter: Calculates IBS = (Close - Low) / (High - Low) for Monday's candle. Entry is permitted only if IBS <= InpIBSMax . If High equals Low, the day is ignored and logged.
• Moving Average (MA) Filter: Requires Monday’s close to be strictly below a Simple Moving Average ( InpMAPeroid ) calculated over closed D1 candles including Monday.

⚙️ Key Specifications

• Chart Timeframe: Timeframe independent (uses D1 series internally). Attaching to a D1 chart is recommended for clean log monitoring.
• Symbol Compatibility: Multi-index compatible (US500, UK100, GER40, etc.).
• Risk Management: Strict 1-position limit with robust retry logic for order execution and emergency closes.

Inputs

The core logic in three excerpts

The following excerpts are cut verbatim from the submitted source. They are selected excerpts of the decision logic, not complete runnable programs. Signal (rule 1):

//--- RULE 1 ------------------------------------------------------
   // DECISION D8: "below" is a strict comparison, an equal close is a no-trade week.
   if(!(bar.close < refBar.close))
      return(StringFormat("SKIP - rule 1: the Monday close %s is not below the previous trading day's close %s (equal or above).",
                          DoubleToString(bar.close, _Digits), DoubleToString(refBar.close, _Digits)));

Filters (IBS and long-term MA):

//--- FILTER 1: IBS ----------------------------------------------
   if(InpUseIBS)
   {
      if(!haveIBS)
      {
         // DECISION D7
         return("SKIP - IBS filter: High == Low on the Monday bar, the ratio is undefined - no-trade day.");
      }
      if(!(ibs <= InpIBSMax))                        // DECISION D8: "<=" as specified
         return(StringFormat("SKIP - IBS filter: IBS %.4f is above InpIBSMax %.4f.", ibs, InpIBSMax));
   }

   //--- FILTER 2: long-term MA -------------------------------------
   if(InpUseMA)
   {
      if(!haveMA)
         return(StringFormat("SKIP - MA filter: not enough daily history to compute the MA(%d).", InpMAPeriod));
      if(!(bar.close < ma))                          // DECISION D8: strict "<"
         return(StringFormat("SKIP - MA filter: the Monday close %s is not below the MA(%d) %s.",
                             DoubleToString(bar.close, _Digits), InpMAPeriod, DoubleToString(ma, _Digits)));
   }

Exit (Wednesday close and later):

   MqlDateTime dtBar;
   TimeToStruct(tBar, dtBar);                        // DECISION D18
   if(!BarIsAtOrAfterWednesday(dtBar.day_of_week))
      return;

   // DECISION D2: the exit is triggered by the close of the Wednesday bar and
   // executed on the first tick after it, retried until the position is flat.
   // DECISION D24: "the bar closed" is MT5's definition - the moment the next
   // daily bar opens on the server clock - not the cash-market closing bell.
   CloseOurPosition(StringFormat("rule 2 - the daily bar %s closed and it is a %s (Wednesday close reached)",
                                 TimeToString(tBar, TIME_DATE), WeekdayName(dtBar.day_of_week)));
