London Structure Trader – MT5 Expert Advisor
London Structure Trader is a structured, session-based MT5 Expert Advisor designed to trade EURUSD during the London session using VWAP directional bias, market structure breaks, and order block execution with controlled risk.
The EA prioritizes precision and capital protection. Trades are taken only after confirmed structure alignment and are protected by predefined stop loss, take profit, and multiple safety filters. Overtrading, grid systems, and martingale techniques are strictly avoided.

Strategy Overview
London Structure Trader follows a multi-layered execution model:
-
Session control
-
VWAP trend bias
-
Market structure break (BOS)
-
Order block retracement
-
Risk-defined execution
Trades are evaluated only on closed candles. No repainting logic is used.
Session Logic
-
Trading is restricted to a configurable London session window using broker server time.
-
VWAP calculation resets at the start of each new session.
-
Optional restriction to:
-
One trade per BOS
-
One trade per session
-
When the session ends, all internal session variables are reset.
Trend Filter (VWAP)
-
A session VWAP is calculated using real market volume.
-
Trade direction is strictly filtered:
-
Buy setups are allowed only when price is above VWAP.
-
Sell setups are allowed only when price is below VWAP.
-
-
Counter-trend setups are ignored entirely.
This ensures all trades follow the dominant intraday bias.
Market Structure (Break of Structure)
-
Market structure is detected using swing highs and lows based on a configurable lookback.
-
A Break of Structure (BOS) occurs when price closes beyond a valid swing level.
-
Only BOS events that align with the VWAP direction are considered.
-
Optional restriction allows only one trade per BOS.
No trades are taken without a confirmed structure break.
Order Block Logic
-
After a valid BOS, the EA identifies the last opposite candle before the break:
-
Buy setup: last bearish candle before bullish BOS
-
Sell setup: last bullish candle before bearish BOS
-
-
This candle defines the order block zone.
-
Wick penetration into the order block is allowed.
-
A full candle body break invalidates the order block.
The EA waits for price to retrace into the order block before evaluating an entry.
Entry Execution
-
Entries are evaluated only after:
-
A valid BOS
-
A valid order block
-
Price retracement into the order block
-
-
Trades are executed only when all conditions are met.
-
Maximum open trades are limited by user input (default: one).
Risk Management
Position Sizing-
Fixed lot size or percentage-based risk per trade.
-
If fixed lot size is set to zero, percentage risk is used automatically.
-
Buy: below the order block low plus a configurable buffer.
-
Sell: above the order block high plus a configurable buffer.
-
Take profit is calculated as:
-
Risk-based target using a configurable risk-to-reward ratio
-
Capped by a maximum pip target
-
-
The EA automatically selects the smaller of the two.
