## 1. What this robot does
A supply or demand zone is a small area where price paused and then left violently - evidence that a large order was filled there and more remains. The robot looks for a tight base of a few bars followed by an impulsive departure, and takes the trade when price comes back into that base.
## 2. Exact trading rules
1. A base is 3 bars whose total range is under 0.7 x ATR.
2. The move away from the base must exceed 1.8 x ATR to qualify as impulsive.
3. Demand zone: price left upwards - BUY when price returns into the base.
4. Supply zone: price left downwards - SELL when price returns into the base.
5. Stop Loss 1.5 x ATR beyond the zone, Take Profit 2.8 x ATR.
## 3. Risk management built in
| Protection | What it does |
|---|---|
| Percent risk sizing | Lot size is calculated from `InpRiskPercent` and the real stop distance, so every trade risks the same fraction of the balance. |
| Fixed lot mode | Set `InpUseRiskPercent = false` to use `InpFixedLot` instead. |
| Hard lot cap | `InpMaxLot` can never be exceeded, whatever the balance. |
| One position rule | `InpMaxOpenTrades` (default 1) - no stacking, no averaging down. |
| Daily loss stop | Trading halts for the rest of the day after `InpDailyLossStopPct` percent loss. |
| Daily trade cap | `InpMaxTradesPerDay` limits overtrading (0 = unlimited). |
| Spread guard | No entry while spread is above `InpMaxSpreadPoints`. |
| Break-even | Stop moves to entry after `InpBE_ATR` x ATR of profit. |
| ATR trailing stop | Locks in profit as the move extends. |
**No martingale guarantee.** The position size function of this EA reads only the account balance, the
risk percent and the stop distance. It never reads the result of the previous trade, so a loss can
never increase the next lot size. There is no grid, no hedge basket and no recovery multiplier
anywhere in the code.

## 5. Installation
The robot ships **compiled**. There is nothing to build and no source file to copy.
1. In MetaTrader 5: **File -> Open Data Folder** -> open `MQL5\Experts\` -> create a folder `PipFix`
2. Copy **`PipFix_SmcSupplyZone.ex5`** into it
3. Refresh the **Navigator** panel (right-click -> Refresh), then drag **PipFix SmcSupplyZone** onto a
**M30** chart of **XAUUSD**
4. On the **Common** tab tick **Allow Algo Trading**
5. On the **Inputs** tab press **Load** and select
**`Settings/PipFix_SmcSupplyZone_XAUUSD_M30_BACKTESTED.set`**
(or the `_LOWRISK` version for half the risk)
6. Make sure the **Algo Trading** button in the toolbar is green
## 6. How to reproduce the backtest
1. **View -> Strategy Tester** (Ctrl+R).
2. Expert: `PipFix\PipFix_SmcSupplyZone`, Symbol: **XAUUSD**, Period: **M30**.
3. Modelling: *Every tick based on real ticks* (or *1 minute OHLC* for a fast first pass).
4. Set the date range, deposit and leverage you want to publish, load the `.set` file, press **Start**.
5. When it finishes, open the **Backtest** tab, right-click -> **Report** to save the HTML/XML report.
The measured results for this EA are in `Backtest/BACKTEST_RESULTS.md` in this folder, together with
the report screenshots. Those numbers come from an actual Strategy Tester run - the settings, symbol,
period and date range used are printed at the top of that file so anyone can repeat it.
## 7. Honest notes
* Past backtest performance is not a promise of future results. Spread, swap and execution differ
between brokers, and a different broker will produce a different curve.
* This robot trades one position at a time with a fixed stop. It is designed to survive, not to
produce a straight equity line.
* Use it on a demo account for at least a few weeks before risking real money.
