NOVA SHIELD EA

Platform: MT5 ==> With Source. Experienced Dev required. EA Written for Exness XAUUSD

Platform: MT5 
Version: Final

NovaShield EA is a Directional Trend Grid Trading System.
The EA trades in only one direction, determined exclusively by the EMA trend:

• If price is above the 200 EMA → EA opens BUY-only trades

• If price is below the 200 EMA → EA opens SELL-only trades

All modules—entries, martingale, pyramiding, break-even, trailing, and protection—must strictly follow this direction.

2.1 EMA Trend Filter (Directional Control)

Directional Rule:

2.2 RSI Filter

Used for additional entry filtering if RSI filtering is enabled.

2.3 EMA Distance Filter

If the price is farther than the allowed distance → no new trades.

A new position is allowed only if ALL filters pass:

• EMA direction filter

• Spread filter

• Time session filter

• News filter

• RSI filter (optional)

• EMA distance filter (optional)

• Anti-order-spam delay (developer must implement)

Initial Lot

NovaShield EA uses two engines, both strictly following the EMA direction:

• Martingale Averaging Down Engine

• Pyramiding Averaging Up Engine

Parameters

Three-Phase Lot Scaling

Martingale Condition

Note:

• Pip calculation must adapt to symbol Digits (XAUUSD vs XAUUSDc).

• EA must never open opposite-direction martingale.

        EnablePyramiding       = true  
PyramidingTriggerPips  = 30  
PyramidingMultiplier   = 1.0  
PyramidingMaxOrders    = 100

    
    
    

Pyramiding Condition

5.1 Group Break-Even

When total floating profit ≥ Trigger →
Move SL of all positions to +10 pips.

5.2 Group Trailing Stop

When total floating profit ≥ 80 pips → activate group trailing.

5.3 Global Equity Protection (Cut-Loss Shield)

If account equity ≤ CutLossEquity:
→ Close ALL orders immediately
→ Block new entries until equity rises above threshold.

6.1 Time Session Filter

Outside this window → no new trades.

6.2 Spread & Slippage Filter

If spread > MaxSpreadPips → block entry.

6.3 Leverage Filter

If account leverage < RequiredLeverage → block entry.

6.4 High-Impact News Filter

    


    


    

        


        


        

            


            


            

        
        
        
    
    
    


    


    


    

        EnableNewsFilter    = true  
PauseBeforeNewsHrs  = 2  
PauseAfterNewsHrs   = 1

    
    
    

During the news lock window:

• No new trades

• No martingale

• No pyramiding

• Break-Even / Trailing / SL / Cut-Loss still active

News Source:
MQL5 built-in Economic Calendar (recommended)

Purpose

A hidden stop-loss system that closes trades internally without placing SL values on the server, preventing brokers from hunting visible stops.

Hidden SL should:

1. NOT set any visible SL on orders sent to the server.
   → All SL logic must be internal inside the EA.

2. Continuously check floating loss:

    

        

            

        
    


    

        If (Current Floating Loss in pips ≥ HiddenSL_Pips)
      → Close the individual position immediately

    

3. “Pips” must be calculated using the correct Digits of the symbol (XAUUSD vs XAUUSDc).

4. The module must work independently of:

• Break-even

• Trailing stop

• Equity Cut Loss

5. Applies to every single order individually:

6. Should NOT trigger during:

• News Lock

• Time Filter lock
  (because those filters block entries, not exits)

Hidden SL must always remain active to protect the account.

    

        

            

        
    


    

        for each order in Orders:
    profitPips = CalculatePips(order.open_price, current_price)

    if (EnableHiddenSL == true)
        if (profitPips <= -HiddenSL_Pips)
             CloseOrder(order)

    

Works alongside:

• Martingale Engine

• Pyramiding Engine

• EMA Direction filter

• Group BE & Trailing

• Equity Cut-Loss shield

Priority:

If multiple exit conditions trigger simultaneously:

1. Equity Cut Loss (highest priority)

2. Hidden SL

3. Group BE / Trailing Stop

4. Take Profit

• Must NOT send SL to server.

• Must NOT modify SL value through OrderModify.

• Close trades only through internal logic.

• Must avoid repeated close signals (add small cooldown per order).

• Works on OnTick (recommended) or timer.

8. Developer Notes

• Must handle pip/point calculations correctly depending on symbol Digits

• Must implement retry logic for OrderSend/OrderModify errors

• Must use SymbolInfo* functions (no deprecated MarketInfo)

• Must prevent order spamming (minimum tick/time delay between trades)

• Must ensure compatibility with real ticks & backtesting

• All trade operations must strictly follow EMA directional filter
