Tested settings for the London session on GBPUSD

London Edge Presets is a collection of six .set files for MetaTrader 4 that configure Helix Algo Studio's two London-session Expert Advisors, Shadow GBPUSD and Phoenix Session EA, for specific broker conditions on GBPUSD. Presets do not change how an EA works; they set its inputs. The value of this pack is the testing behind each file and the plain-language notes that explain which preset to load for your account type and spread, so you do not have to spend evenings in the strategy tester before your first trade.

What is in the pack

For Shadow GBPUSD there are three presets. ECN Tight assumes a London-open spread under 1.2 pips and uses the narrowest breakout buffer; Standard covers spreads up to 2 pips with a wider buffer and a slightly later cancel time; Cent Account mirrors Standard but with fixed micro-lot sizing suited to cent-denominated balances. For Phoenix Session EA there are three matching presets that enable only the London session, adjust the volatility skip threshold for GBPUSD's larger range and set the daily stop conservatively. All six were exported from the current EA versions and are named with the version they target.

How they were tested

Each preset was run in the MT4 strategy tester on imported GBPUSD tick data from January 2022 to December 2025 using the fixed spread stated in its notes, then forward-checked on a demo account through the first half of 2026. The pack's PDF shows the tester summary for every preset side by side, including maximum drawdown and the longest losing run, so you can compare them honestly rather than picking the one with the highest number. Those tester summaries are sample data and are not projections.

Loading a preset

Presets load from the EA's Inputs tab with the Load button. Because MetaTrader silently ignores inputs it does not recognise, each preset states the exact EA version it was exported from, and the PDF lists which inputs were added or renamed between versions. Loading a preset into an older EA build will not break anything, but new inputs will keep their defaults, which is why the pack is refreshed whenever the EAs change.

Keeping presets current

Broker conditions drift. When average London-open spreads or GBPUSD volatility change enough to move a preset outside the range it was tested for, Helix publishes a revised pack as a free update. The changelog records what moved and why, so you can decide whether to reload. Updates are included for the lifetime of the pack.

What this pack is not

London Edge does not include the Expert Advisors themselves; you need a license for Shadow GBPUSD or Phoenix Session EA, both sold separately on this marketplace and both included with membership. It is not a set of optimised-to-the-past curve fits; the inputs were chosen for robustness across the whole test period and deliberately left slightly wider than the best single-year result. And it is not a promise of profit: the same EA with the same preset will behave differently at different brokers, which is the reason the pack exists.

• MetaTrader 4 build 1415 or later.
• An active license for Shadow GBPUSD 1.8.x or Phoenix Session EA 2.2.x; the pack contains no Expert Advisor files.
• GBPUSD on an ECN, standard or cent account; choose the preset matching your typical London-open spread.
• Correct broker GMT offset entered in the EA, exactly as for the EA alone.

1. Download and extract the archive from your account. It contains six .set files and the PDF.
2. In MetaTrader 4 open File > Open Data Folder and copy the .set files into MQL4/Presets.
3. Restart the terminal, or simply reopen the EA properties dialog; presets do not require a restart to appear.
4. Make sure AutoTrading is enabled and the target EA is attached to a GBPUSD M15 chart.
5. Open the EA's properties, go to the Inputs tab and click Load.
6. Select the preset whose notes match your account type and spread, then click OK.
7. Re-enter your license email and GMT offset if the preset reset them, and check the chart label shows the expected session window.
