PROJECT: MT5 EA – Opening Range Breakout (ORB) with Williams Lines (M1 + M5)
DELIVERY: 3 days
TESTING: 10 days demo
SUPPORT: 1 month bug-fix
BUDGET: 100 USD+

The EA must run independent ORB engines on M1 and M5 (1 trade per session per timeframe) for multiple assets and sessions (EU/US/Asia).

------------------------------------------------------------
CORE LOGIC
------------------------------------------------------------
- Range detection via Williams lines:
  • Dashed line = first candle high/low not broken  
  • Solid line = second candle also not breaking → confirmed  
- A range is tradable when ONE side is confirmed and the opposite side is still dashed (provisional).
- Mandatory MaxRange:
  GER40 = 100 pts, NAS100 = 140 pts, JP225 = 280 pts  
  Optional MaxRange for other assets.
- If provisional side becomes invalid → replace only that side:
  • Wait for 1 new dashed line + 1 new confirmed line  
  • Confirmed side stays unless broken or violating MaxRange  
  • Delete pending orders when opposite side is replaced

------------------------------------------------------------
ENTRY
------------------------------------------------------------
Buy: confirmed upper + dashed lower → BuyStop above RangeHigh + offset  
Sell: confirmed lower + dashed upper → SellStop below RangeLow + offset  
- Only 1 trade per session per timeframe  
- Delete orders at session end  
- If price breaks range before entry → cancel setup

------------------------------------------------------------
STOP, RISK, TP
------------------------------------------------------------
- SL = opposite side of range  
- Risk-based lot calculation  
- Break-Even: at +1R → SL = EntryPrice (optional BE offset)  
- TP includes spread offset (2–3 pts):
  Buy: +SpreadOffset  
  Sell: -SpreadOffset  

------------------------------------------------------------
OPTIONAL FILTERS
------------------------------------------------------------
- MACD (H1), ATR, MaxSpread  
- Swing trailing after BE (SwingBars 2–5)
