feat: EA report parser and performance evaluation guide

- Add scripts/parse_tester_report.py: parses MT5 Strategy Tester HTML
  reports (UTF-16LE). Extracts settings, EA parameters, 44 P&L metrics,
  orders (192), deals (193), stop-out detection. Supports --json output.
- Add Report Analysis subsection to SKILL.md Section 6: 10 evaluation
  dimensions (data quality, profitability, drawdown, trade distribution,
  consecutive losses, holding time, MFE/MAE, stop-out, bias, commission).

### Report Analysis — Interpreting Tester Results
After each backtest, MT5 exports an HTML report. Use
`scripts/parse_tester_report.py` to extract structured data, or read the
HTML directly. Key areas to evaluate:
#### 1. Data Quality Gate
**Always check first.** If history quality is poor, all metrics are suspect.
| Metric | Acceptable | Action if Failed |
|--------|-----------|-----------------|
| History Quality | ≥ 95% real ticks | Re-download tick data or use different broker |
| Bars | Enough for strategy (e.g. 1000+ for H4) | Extend test period |
| Modelling quality | Every tick or Every tick based on real ticks | Never trust "Open prices only" for final eval |
#### 2. Profitability Metrics
| Metric | Good | Warning | Bad |
|--------|------|---------|-----|
| Net Profit | > 0 | ≈ 0 | < 0 |
| Profit Factor | > 1.5 | 1.01.5 | < 1.0 |
| Expected Payoff | > 0 | ≈ 0 | < 0 |
| Recovery Factor | > 2.0 | 1.02.0 | < 1.0 |
**Profit Factor < 1.0** = guaranteed loss. The EA loses more than it wins.
No amount of parameter tuning will fix a fundamentally negative PF — the
strategy logic itself needs rethinking.
#### 3. Drawdown Analysis
Drawdown is the real killer. A 100% drawdown means account wiped.
| Metric | Safe | Risky | Dangerous |
|--------|------|-------|-----------|
| Max DD% | < 20% | 2050% | > 50% |
| DD Absolute / Deposit | < 0.5x | 0.51x | > 1x (blown) |
**Check both Balance DD and Equity DD.** Equity DD captures floating
losses that haven't realized yet — often much worse than balance DD.
If `Balance DD Max% ≈ 100%`, the account was wiped. Look at the balance
curve: did it recover or flatline at zero?
#### 4. Trade Distribution
| Metric | Healthy | Concerning |
|--------|---------|------------|
| Win Rate | 4060% | < 30% or > 70% |
| Avg Win / Avg Loss | > 1.5 | < 1.0 |
| Profit Trades % | > 40% | < 30% |
| Largest Loss / Avg Loss | < 3x | > 5x (outlier risk) |
Low win rate is fine if avg win >> avg loss (trend following).
High win rate is fine if avg loss << avg win (mean reversion).
**Red flag**: low win rate AND small avg win = guaranteed bleed.
#### 5. Consecutive Losses
| Metric | Tolerable | Stressed |
|--------|-----------|----------|
| Max Consecutive Losses | < 5 | > 8 |
| Max Consecutive Loss $ | < 2x deposit | > deposit |
More than 8 consecutive losses suggests the strategy has long anti-trend
periods. With martingale or grid sizing, consecutive losses compound
catastrophically.
#### 6. Holding Time
| Pattern | Meaning | Risk |
|---------|---------|------|
| Very short avg (< 1 min) | Scalping / arbitrage | Spread/slippage sensitive |
| Very long avg (> 100 hrs) | Swing / position trading | Gap/overnight risk |
| Huge variance (min vs max) | Mixed strategy | Hard to predict behavior |
#### 7. MFE/MAE Analysis
- **MFE (Most Favorable Excursion)**: how far price went in your favor
before exit. High MFE + low profit = premature exit (tight TP).
- **MAE (Most Adverse Excursion)**: how far price went against you.
High MAE + small loss = lucky exit (SL barely held).
- **Correlation (Profits, MAE)**: high positive = losses come from
large adverse moves (SL too loose or absent).
- **Correlation (MFE, MAE)**: negative = when price moves far in one
direction, it doesn't retrace (good for trend following).
#### 8. Stop-Out Detection
Stop-outs (comment contains `so`) mean margin was insufficient — the
broker force-closed before SL was reached. This is always a critical bug:
```
Root causes:
1. SL too far from entry → floating loss exceeds available margin
2. Lot size too large for account balance
3. Risk per trade exceeds account capacity
4. Multiple concurrent positions drain margin
```
Fix: reduce lot size, tighten SL, or reduce concurrent positions.
#### 9. Short vs Long Bias
Compare `Short Trades (won%)` vs `Long Trades (won%)`:
- Heavily skewed (e.g. 91 long / 5 short) → EA only trades one direction
- Check if this is intentional (bullish filter) or a bug
- In trending markets, one-direction bias can mask poor signal quality
#### 10. Commission & Swap Impact
In the Deals table, check `Commission` and `Swap` columns:
- Commission should be consistent per deal (proportional to volume)
- Swap accumulates on overnight positions — can turn winners into losers
- `Profit = Price P&L + Commission + Swap` — verify this sums correctly
