Episode 8 [Practical Edition]: Thorough guide from immediate start to backtest

? Do grid trading users achieving 40% monthly return keep appearing! What’s the secret?

⚡ Immediate Start Grid Feature

Deploy the grid as soon as the EA starts! Fully automated trading

? Post-Launch Operational Flow

Step 1: Start EA
Attach ELDRA to the chart

Step 2: Determine Price Range (0.1 seconds)
• Upper limit price = 0: automatically derived from current price
• Lower limit price = 0: automatically derived from current price
• If manually set: use that value

Step 3: Calculate Grid Levels (0.2 seconds)
Distribute the configured number of levels (e.g., 10) evenly within the price range

Step 4: Place All Pending Orders (1–3 seconds)
Place Buy Limit / Sell Limit all at once

Step 5: Done!
Then prices move and orders are filled automatically, repeating take profits

? True vs False Thorough Comparison

✅ Grid Start Immediately = True (Automatic Start)

• Grid deployment at EA startup
• Auto-recovery on chart changes
• Auto-resumes after PC restart
• 用途: Fully automated operation, backtesting essential

❌ Grid Start Immediately = False (Manual Start)

• EA starts in standby
• Need to manually press the “Grid Start” button on the panel
• State is preserved on chart changes (stored in globals)
• 用途: When you want to decide the grid start timing by discretion

? Example: Fully passive operation with True setting

Case of Trader A

• Setting: Grid Start Immediately = True
• Currency pair: USD/JPY
• Upper limit price: 0 (automatic)
• Lower limit price: 0 (automatic)
• Grid levels: 20
• Grid spacing: 200 points (20 pips)

Operational results (1 month)

• EA start count: 1 (set at month start and left running)
• Total trades: 347 (all automated)
• Monthly return: +42.3%

Comment from A：
“Once set, I really don’t touch it. I wake up to profits. This is true passive income.”

? Recommended settings by用途

Want fully automated operation:True ←Recommended

Want to verify with backtests:True ←Essential

Want to decide timing by discretion：False

Want to start after assessing market conditions：False

⚠️ Important Points When Using

• When True is set, be careful with price range settings (too wide may exhaust funds; too narrow may miss opportunities)
• Always set True for backtests (False does nothing)
• Beginners should practice with False first, then automate with True
• When restarting EA, check existing grid orders (duplicate prevention feature present)

? Complete Guide to Grid Backtesting

Achieve over 90% win rate with proper verification methods

? 5-Step Backtest Procedure

Step 1: Open Strategy Tester

MT5 Menu →View → Strategy Tester(Ctrl+R)

Or click the “Strategy Tester” tab at the bottom of the screen

Step 2: Basic Settings

• Expert：Select ELDRA (or ELDRA_1C304161...)
• Currency Pair：USD/JPY (recommended) or EUR/USD
• Period：H1 recommended; M15–H4 OK
• Model：“Every Tick” ← highest precision (more time-consuming)
• Date Range：Minimum 3 months, 6–12 months recommended

Step 3: Grid Parameter Settings (Extremely Important!)

Click “Settings” or “Expert properties” and set the following:

Mandatory Settings:

• ✅Grid Start Immediately = True← Forgetting this and nothing will move!
• Grid upper price = 0 (automatic)
• Grid lower price = 0 (automatic)
• Grid levels = 10–20 (10 recommended for beginners)
• Grid spacing = 200 points (20 pips recommended)
• Grid Lot = 0.01 (safety first)

Grid TP Settings：

• ✅ Grid TP Enabled = True
• Grid TP Points = 50 (5 pips take profit)

Disable other features：

• ❌ Hedging Entry Mode = 0 (OFF) ← Important!
• ❌ Averaging Up/Down (Nampin) = False
• ❌ Indicator Mode = 0 (disabled)

Step 4: Run Backtest

Click the “Start” button → progress bar appears

Estimated time:

• 3 months of data: 5–15 minutes
• 1 year of data: 20–60 minutes
• 5 years of data: 1–3 hours

※ When using “Every Tick” mode. Varies by PC specs

Step 5: Result Analysis

Metrics to check：

1. Total Net Profit
→ Positive is pass; negative, revise settings

2. Profit Factor
→ ≥1.5: excellent
→ ≥2.0: very excellent
→ ≥3.0: professional level

3. Max Drawdown
→ Within 15% of initial capital: safe
→ ≥30%: dangerous (needs settings review)

4. Win Rate
→ grid trading typically 80% or higher
→ ≥90% is perfect

5. Graph Shape
→ Upward slope with no sharp drops = ideal
→ Sharp jaggedness = unstable (needs setting adjustments)

? Example: Backtest results of Professional Trader B

Test Conditions

• Currency pair: USD/JPY
• Period: Jan 1–Dec 31, 2024 (1 year)
• Grid levels: 15
• Grid spacing: 200 points
• Grid TP: 50 points
• Initial capital: ¥100,000

Results

• Total Profit：+65,580 yen (+64.6%)
• Total trades: 1,247
• Win rate：92.3%
• Profit factor：3.12
• Max drawdown：-8,340 yen (-8.3%)

B’s comment：
“Backtesting showed 92% win rate, so I started real trading with confidence. Real results are similar.”

? A Behind-the-Scenes Trick Only Pros Know About Backtesting

Trick 1: Validate across multiple periods

Not just a single period, but test across 3 or more different periods:

• Trending periods (e.g., Jan–Mar 2024)

If all are positive,that’s a real settings.

Trick 2: Test with different currency pairs

If USD/JPY gives good results, try EUR/USD, GBP/USD as well.
If results are consistent across multiple pairs,a highly versatile setting.

Trick 3: Find the worst period

Identify the period with the largest drawdown on the chart. Re-test only that period and analyze how to handle it.

Trick 4: Try three spacing patterns

• 150 points (15 pips) ← narrow
• 200 points (20 pips) ← standard
• 300 points (30 pips) ← wide

Compare results and adopt the most stable one.

⚠️ Backtesting Pitfalls

• Models other than “Every Tick” have lower accuracy (numbers may look good but not reliable)
• Backtests can look good but must be verified with forward tests (demo accounts)
• Check spread settings (too narrow can give unrealistic outperformance)
• Over-optimizing to historical data causes failure in real trading (curve-fitting)

?️ Volatility Filter

Automatic brakes on sudden moves! The last line of defense to protect the grid

? Correct understanding: What is Volatility Filter?

❌ Common misconception

“A feature that automatically adjusts grid width using ATR × ATR multiplier”

✅ Correct understanding

“When ATR is high (volatility overstated), a safety mechanism pauses the gridtemporarily.”

Actual operation：

• Normal times: grid is operating
• ATR jumps (economic news, flash crashes, etc.)
• → Filter triggers:Delete all pending orders
• ATR falls back (market settles)
• → Filter releases: grid automatically resumes

? Calculation of Filter Activation Conditions

Example settings：

• ATR period: 14
• ATR multiplier: 2.0

Calculation：

1. Current ATR calculation: e.g., 0.50 (50 pips)
2. Average of last 2 bars ATR: e.g., 0.48 (48 pips)
3. Threshold = average ATR × multiplier = 0.48 × 2.0 =0.96

Decision:

• Current ATR (0.50) < Threshold (0.96) →✅ Filter passes, grid continues
• Current ATR (1.20) > Threshold (0.96) →❌ Filter fails, grid paused

? Example: Filter saved in US Nonfarm Payrolls

Situation: March 8, 2024 22:30 US Nonfarm Payrolls release

Filter OFF:

• USD/JPY from 149.50 to 151.20 surged (+170 pips)
• Grid pending orders executed one after another
• Owns 15 short positions within 3 minutes
• Average entry price: 150.35
• Price kept rising to 151.50...
• Result: loss -187,000 yen（Initial margin 100,000 yen → near bankruptcy）

Filter ON:

• ATR before release: 0.45
• ATR at release: 1.35 (jumped to 3x!)
• Threshold exceeded 0.90 →Filter activated
• Delete all pending orders, no new entries
• Keep existing 2 positions
• Close positions when price returns to 150.80
• Result: loss only -12,000 yen

? Recommended settings by market condition

Standard settings (universal type):

• Volatility Filter: ON
• ATR Period:14
• ATR Multiplier:2.0

Conservative (risk minimized):

• Volatility Filter:ON
• ATR Period:14
• ATR Multiplier:1.5← Stricter

Profit-Focused (maximize opportunities):

• Volatility Filter:ON
• ATR Period:14
• ATR Multiplier:2.5–3.0← Looser

Defense only during economic releases：

• Volatility Filter:ON
• ATR Period:7← React quickly with short-term ATR
• 2.0

⚠️ Cautions When Using

• Filter activation = also loses profit opportunities (trade-off)
• If ATR multiplier is below 1.0, it will pause constantly
• In trending markets, it may trigger frequently
• In range-bound markets, 2.0–3.0 multiplier is appropriate
• Backtest with ON and OFF to compare recommended

? Summary: The 3 Rules of Grid Trading

Three key points learned this time：

1. Grid Start Immediately = True for full automation
   → Deploy grid at EA startup and earn by leaving it running
   → Essential setting for backtesting
2. Verify with correct backtesting procedures
   → 5-step process enables perfect verification
   → Check across multiple periods and currency pairs
   → Profit factor ≥ 2.0 and win rate ≥ 80% as benchmarks
3. Operate safely with Volatility Filter
   → Grid automatically stops during sudden moves
   → Grid width does not change (only stopping)
   → Standard ATR multiplier is 2.0; 1.5 is safety-focused
