# 🚀 MT5 Set‑File Specialist Needed – Robust Presets for Existing Scalper EA (Prop‑Firm Conditions)
## Project Overview
I already have a fully coded MT5 Expert Advisor (`MultiSymbol_Scalper_EA.mq5`) that trades a mean‑reversion / scalping framework.
I am **not** looking for a new EA or strategy code. I need an experienced MT5 quant/optimizer to build **robust .set files** for multiple FX pairs under strict **prop‑firm style** testing conditions.
**IMPORTANT: All communication must be in English.**
---
## Symbols and Scope
Initial list of pairs (this may expand later):
- EURUSD
- USDJPY
- GBPUSD
- GBPJPY
- USDCAD
- EURGBP
- AUDUSD
- AUDNZD
You can indicate which of these you are confident to cover; we can agree final scope and budget per symbol.
---
## Testing Rules (Must Follow Exactly)
All optimisation and validation must be done **inside MT5 Strategy Tester** using:
- **Modelling**: `Every tick based on real ticks`
- **Execution**: `Random delay` (to simulate real execution, not idealised backtests)
- **Data range**: Normally **Jan 2024 → present**, or as I specify per symbol
- **Account style**: Prop‑firm style (e.g. initial balance 5 000 USD, leverage 1:30 – exact details will be provided)
- **Forward test split**: At least **30–40%** of the total period dedicated to forward testing (out‑of‑sample)
For each candidate preset, the **forward period** metrics are what matter most.
### Minimum Performance Targets (Per Symbol)
On the **forward** segment:
- **Profit Factor**: ≥ **1.30**
- **Max equity drawdown**: ≤ **10%**
- **Total trades (back + forward)**: ≥ **60 trades**
(I prefer more trades if PF and DD stay acceptable.)
Backtest PF can be higher, but I will reject any presets that only look good in‑sample and collapse in forward.
---
## Your Task
For each agreed symbol:
1. Design and run optimisations / walk‑forward style tests to search for **robust** parameter combinations.
2. Produce at least **one main preset** per symbol that meets the performance targets above under the specified test conditions.
3. Optionally provide **1–2 alternate presets** per symbol where there is a clear trade‑off, e.g.:
- Higher PF but fewer trades, or
- More trades but slightly higher DD.
4. Avoid obvious over‑fitting:
- No extreme parameter values that only fire a few times.
- Preferring smooth performance across multiple months rather than a single hot period.
**Important:** This job is about **inputs only**. Do **not** change the strategy logic or code unless we explicitly agree a small, well‑defined modification.
---
## Deliverables
For each symbol you work on:
1. **Preset Files**
- `.set` files with clear names (e.g. `EURUSD_Prop_M5_Main.set`, `USDJPY_Prop_M5_Alt1.set`).
2. **Test Evidence**
- Screenshots of MT5 Strategy Tester **Backtest** and **Forward** result pages, showing:
- Profit Factor
- Max equity drawdown (absolute and %)
- Total trades
- Test period and modelling settings (Every tick + Random delay)
3. **Short Notes**
- 2–4 lines per preset describing:
- Overall style (conservative / balanced / aggressive)
- Any notable behaviour (e.g. more active during London/NY, more sensitive to spreads, etc.)
---
## What I’m Looking For in a Freelancer
- Strong experience with **MT5 optimisation and robustness testing**.
- Comfortable working with:
- Forward testing / walk‑forward validation
- Parameter range design (not brute‑force random overfitting)
- Reading and interpreting PF/DD/trade‑count trade‑offs.
- Ideally: prior experience preparing EAs for **prop firms** (FTMO, 5%ers, etc.).
### In Your Proposal, Please Include
- A brief description of similar work you have done (optimising EAs, building set files).
- How you normally avoid **overfitting** (e.g. forward testing, multiple date ranges, parameter clustering, etc.).
- An indication of:
- How many symbols from the list you can realistically cover, and
- Your estimated price **per symbol** or for the whole package.
---
## Project Timeline & Budget
- Timeline: Flexible, but I prefer staged delivery (e.g. 2–3 symbols first, then the rest).
- Budget: To be discussed based on number of symbols and your experience. Please quote a **per‑symbol** price in your bid.
---
## Important Notes
- **No new EA coding is required** – this is an optimisation / research job on an existing EA.
- **All communication must be in English.**
- I reserve the right to request reasonable adjustments if a preset shows signs of overfitting when I re‑test it on my side.
