Will the market settle inside this price window, or will it break free before expiry? The Ends Between/Ends Outside contract is a Range Digital Option where the outcome depends only on the market price (Exit Spot) relative to two custom price levels (Barriers) at the exact moment of contract expiry. Price can dance anywhere during the trade - only the final tick determines victory or defeat.
Welcome to Lesson 3
You have mastered directional prediction (Rise/Fall) and single-barrier targeting (Higher/Lower). Now you will learn range prediction - the art of forecasting where price will NOT be, or where it WILL settle.
The power of dual barriers: Instead of betting on price direction or a single target, you define a complete price window with High and Low Barriers. You bet on whether price will end inside or outside this window.
Strategic Duality: Ends Between wins when market consolidates (low volatility at expiry). Ends Outside wins when market breaks out (high volatility sustains until expiry). Two contracts, two volatility philosophies, infinite strategic combinations.
Lesson Chapters
1Chapter 1: Introduction and Definition~3 min
The Ends Between/Ends Outside contract is a Range Digital Option where the outcome depends only on the market price (Exit Spot) relative to two custom price levels (Barriers) at the exact moment of contract expiry. This is an expiry-dependent range contract.
🎯 Two Sides of the Same Coin
Ends Between:
- You win if the Exit Spot is strictly within the High and Low Barriers
 - Betting on: Consolidation at expiry (price settles inside range)
 - Win condition: Low Barrier < Exit Spot < High Barrier
 
Ends Outside:
- You win if the Exit Spot is strictly outside the High and Low Barriers
 - Betting on: Breakout sustaining until expiry (price ends beyond range)
 - Win condition: Exit Spot > High Barrier OR Exit Spot < Low Barrier
 
Critical Distinction:
- NOT path-dependent: Price can touch or cross barriers during the trade
 - Expiry-only settlement: Only the final tick (Exit Spot) matters
 - If you confuse this with Stays Between/Goes Outside (path contracts), you will lose money
 
How This Differs From Other Contracts
📊 Range Contract Family Tree
Path-Dependent Range Contracts:
- Stays Between/Goes Outside: Price path matters, instant settlement on barrier touch
 - Win/loss determined at ANY point during contract
 
Expiry-Dependent Range Contracts:
- Ends Between/Ends Outside: Price path irrelevant, expiry-only settlement
 - Win/loss determined ONLY at expiration
 
Your Advantage: With Ends Between/Ends Outside, a mid-trade spike outside your barriers is survivable. If price returns inside before expiry, Ends Between still wins. This forgiveness of intra-trade volatility is the strategic edge.
Key Strategic Insight: Use Ends Between when you predict consolidation AT EXPIRY (not during trade). Use Ends Outside when you predict a breakout that SUSTAINS UNTIL EXPIRY. The timing of the prediction is critical.
2Chapter 2: The Mechanism~5 min
The trader sets the range by defining a High Barrier (positive offset) and a Low Barrier (negative offset).
⚖️ Dual Barrier Mechanics
Setting the Range:
- High Barrier: Positive offset (e.g., +500 points)
 - Low Barrier: Negative offset (e.g., -500 points)
 - Range Width: High Barrier - Low Barrier (e.g., 1,000 points)
 
Example:
- Current Volatility 75: 45,000
 - High Barrier offset: +500 → Barrier at 45,500
 - Low Barrier offset: -500 → Barrier at 44,500
 - Range width: 1,000 points (44,500 to 45,500)
 
Win/Loss Conditions
🎲 Precise Win Conditions
Ends Between Win: The final price must land: Low Barrier < Exit Spot < High Barrier
Example (Range: 44,500 to 45,500):
- Exit Spot: 45,000 ✅ Win (inside range)
 - Exit Spot: 44,501 ✅ Win (inside range)
 - Exit Spot: 45,499 ✅ Win (inside range)
 - Exit Spot: 45,500 ❌ Loss (equal to High Barrier)
 - Exit Spot: 44,500 ❌ Loss (equal to Low Barrier)
 - Exit Spot: 46,000 ❌ Loss (outside range)
 
Ends Outside Win: The final price must land: Exit Spot > High Barrier OR Exit Spot < Low Barrier
Example (Range: 44,500 to 45,500):
- Exit Spot: 46,000 ✅ Win (above High Barrier)
 - Exit Spot: 44,000 ✅ Win (below Low Barrier)
 - Exit Spot: 45,501 ✅ Win (above High Barrier)
 - Exit Spot: 44,499 ✅ Win (below Low Barrier)
 - Exit Spot: 45,000 ❌ Loss (inside range)
 - Exit Spot: 45,500 ❌ Loss (equal to barrier)
 
Tie Rule (Both Contracts): If the Exit Spot is equal to either the High or Low Barrier, the trade is a loss.
🎯 Ends Between Scenarios in Action
✅ Ends Between Success

Price ends inside range = Win
❌ Ends Between Failure

Price ends outside range = Loss
Understanding Ends Between Predictions:
- Success: When you predict Ends Between and price settles inside the range at expiry
 - Failure: When you predict Ends Between but price ends outside the range at expiry
 - Expiry-Only Settlement: Only the final price at expiry matters, not the price path during the trade
 
🎯 Ends Outside Scenarios in Action
✅ Ends Outside Success

Price ends outside range = Win
❌ Ends Outside Failure

Price ends inside range = Loss
Understanding Ends Outside Predictions:
- Success: When you predict Ends Outside and price settles outside the range at expiry
 - Failure: When you predict Ends Outside but price ends inside the range at expiry
 - Breakout Strategy: Perfect for betting on sustained breakouts that hold until expiry
 
Range Width and Payout Relationship
📏 The Width-Payout Dynamic
Ends Between:
- Wider range = Higher probability price ends inside = Lower payout
 - Narrower range = Lower probability price ends inside = Higher payout
 
Ends Outside:
- Wider range = Lower probability price breaks far out = Higher payout
 - Narrower range = Higher probability price escapes = Lower payout
 
Practical Example (Volatility 75 at 45,000):
| Range Width | High/Low Barriers | Ends Between Payout | Ends Outside Payout | 
|---|---|---|---|
| Narrow (400 pts) | 45,200 / 44,800 | 110% | 50% | 
| Medium (1,000 pts) | 45,500 / 44,500 | 65% | 95% | 
| Wide (2,000 pts) | 46,000 / 44,000 | 45% | 140% | 
The Inverse Relationship:
- Wide range: Ends Between pays less (easier to stay in), Ends Outside pays more (harder to break far out)
 - Narrow range: Ends Between pays more (harder to stay in), Ends Outside pays less (easier to escape)
 
Professional Strategy: Match range width to expected volatility at expiry, not current volatility. If you predict low volatility at expiry, use Ends Between with narrow-to-medium range. If you predict high volatility sustaining to expiry, use Ends Outside with wide range.

3Chapter 3: Key Features and Flexibility~4 min
🔧 Contract Parameters
| Feature | Description | 
|---|---|
| Asset | Available on Synthetic Indices (Volatility 10, 25, 50, 75, 100) and select instruments. Best suited for assets with clear volatility patterns. | 
| Duration | Typically used for medium to long durations (5 minutes to 1 hour). Longer durations allow volatility to normalize at expiry. | 
| Payout Style | Fixed Payout. The payout is determined by the width of the range and the duration of the contract. Inversely related for Ends Between vs Ends Outside. | 
| Unique Condition | Expiry-Dependent. Price movement during the contract is irrelevant; only the final tick (Exit Spot) matters. This differentiates it from path-dependent Stays Between/Goes Outside. | 
| Risk | Loss is limited to initial Stake. Maximum loss occurs if Exit Spot ends on wrong side of range (or equal to barrier). | 
Strategic Range Width Selection
📐 Range Width Guidelines
For Ends Between (Consolidation Bet):
Narrow Range (High Risk/Reward):
- Width: ±200-400 points
 - Use when: Very low volatility expected at expiry (end-of-session, post-spike consolidation)
 - Payout: 90-130%
 - Risk: High (price can easily escape narrow range)
 
Medium Range (Balanced):
- Width: ±500-1,000 points
 - Use when: Moderate consolidation expected, normal volatility decline
 - Payout: 60-85%
 - Risk: Moderate (most common range for Ends Between)
 
Wide Range (Conservative):
- Width: ±1,500+ points
 - Use when: High confidence in consolidation but want safety buffer
 - Payout: 40-60%
 - Risk: Low (large room for price fluctuation)
 
For Ends Outside (Breakout Bet):
Narrow Range (Conservative):
- Width: ±200-400 points
 - Use when: High volatility expected, easy breakout anticipated
 - Payout: 45-65%
 - Risk: Low (easy for price to escape)
 
Medium Range (Balanced):
- Width: ±500-1,000 points
 - Use when: Moderate breakout expected to sustain
 - Payout: 85-110%
 - Risk: Moderate
 
Wide Range (Aggressive):
- Width: ±1,500+ points
 - Use when: Massive volatility event, extreme price displacement expected
 - Payout: 120-180%+
 - Risk: High (requires significant sustained movement)
 
Time-Volatility Decay: Volatility tends to decline as contracts approach expiry (mean reversion). This favors Ends Between on longer durations. Use Ends Outside on shorter durations when breakout momentum is fresh.
4Chapter 4: Risk and Reward Profile~4 min
⚠️ Risk Warning: This contract is prone to sudden, unexpected volatility near expiry. A last-second spike, common in volatile indices, can push the Exit Spot just outside your range (Ends Between loss) or pull it back inside (Ends Outside loss), resulting in a loss of your full stake. Never assume the final 30 seconds are safe.
🛡️ Risk Profile
Risk is Limited but Timing-Sensitive:
- Maximum Loss: Your stake amount only
 - No margin calls: Cannot lose more than you invest
 - Expiry volatility risk: Last-second price spikes are the primary danger
 - Barrier equality risk: Exit Spot landing exactly on barrier = loss
 
Risk Factors by Contract Type:
Ends Between Risks:
- Last-second breakout: Price stable mid-trade, then spikes at expiry
 - Narrow range risk: Setting barriers too tight, no room for error
 - Volatile index risk: High-volatility indices (V100, V75) prone to expiry spikes
 
Ends Outside Risks:
- Last-second reversion: Price breaks out mid-trade, returns inside at expiry
 - Wide range risk: Setting barriers too far, price cannot reach
 - Mean reversion: Strong tendency for price to revert toward mean before expiry
 
💎 Reward Profile
Reward Varies by Range Width:
Ends Between Reward:
- Higher reward for narrow ranges (harder to stay inside)
 - Range: 45-130% typical payouts
 - Sweet spot: 60-80% payouts on medium ranges (balanced probability)
 
Ends Outside Reward:
- Higher reward for wide ranges (harder to break far outside)
 - Range: 50-180% typical payouts
 - Sweet spot: 90-120% payouts on medium-wide ranges
 
Profitability Analysis:
| Strategy | Payout % | Win Rate | Calculation | Result | 
|---|---|---|---|---|
| Ends Between (Medium Range) | 70% | 62% | (0.62 × 0.70) - 0.38 = 0.434 - 0.38 | ✅ +5.4% edge | 
| Ends Between (Narrow Range) | 110% | 50% | (0.50 × 1.10) - 0.50 = 0.55 - 0.50 | ✅ +5.0% edge | 
| Ends Outside (Wide Range) | 140% | 45% | (0.45 × 1.40) - 0.55 = 0.63 - 0.55 | ✅ +8.0% edge | 
| Ends Outside (Narrow Range) | 55% | 68% | (0.68 × 0.55) - 0.32 = 0.374 - 0.32 | ✅ +5.4% edge | 
Key Insight: Both contracts are profitable when your win rate exceeds the implied probability. The edge comes from reading volatility conditions better than the market's calculation.
Professional Risk Management: Use Ends Between for end-of-session trades when volatility typically drops. Use Ends Outside for post-news trades when breakout momentum is fresh. Never trade near major news releases without wide buffers.
5Chapter 5: Best-Use Scenarios~5 min
✅ Ends Between Perfect Use Cases
1. Consolidation at Expiry (Most Common)
Scenario: Volatility 75 has been ranging between 44,800-45,200 for 45+ minutes Analysis: Low volatility environment likely to persist until expiry Strategy:

 - Payout: 75%
 
2. End-of-Session Mean Reversion
Scenario: New York session closing in 20 minutes, Volatility 100 at 55,500 after volatile day Analysis: End-of-session volatility typically drops, price reverts to mean Strategy:
- Contract: Ends Between
 - High Barrier: 56,000 (+500)
 - Low Barrier: 55,000 (-500)
 - Duration: 20 minutes (aligned with session close)
 - Logic: Price will settle near mean as traders close positions
 - Payout: 68%
 
3. Post-Spike Exhaustion
Scenario: Volatility 75 just spiked from 44,500 to 46,000 in 2 minutes (news event), now consolidating Analysis: Spike exhausted, reversion/consolidation expected Strategy:
- Contract: Ends Between
 - High Barrier: 46,300 (+300 from current 46,000)
 - Low Barrier: 45,700 (-300)
 - Duration: 10 minutes
 - Logic: Post-spike consolidation, narrow range reflects high confidence
 - Payout: 95% (narrow range, high reward)
 
✅ Ends Outside Perfect Use Cases
1. High-Impact Volatility Event
Scenario: NFP report in 2 minutes, Volatility 75 at 45,000 Analysis: Massive directional move expected, will sustain until expiry Strategy:
- Contract: Ends Outside
 - High Barrier: 45,800 (+800)
 - Low Barrier: 44,200 (-800)
 - Duration: 5 minutes (post-news)
 - Logic: News-driven momentum will push price well beyond range
 - Payout: 105%
 
2. Technical Breakout from Pattern
Scenario: Volatility 100 forming triangle pattern, consolidating 54,500-55,500, breakout imminent Analysis: Breakout will be strong and sustained Strategy:
- Contract: Ends Outside
 - High Barrier: 56,000 (+500 from current 55,500)
 - Low Barrier: 54,000 (-500)
 - Duration: 15 minutes
 - Logic: Breakout momentum carries price far from consolidation zone
 - Payout: 90%
 
3. Momentum Continuation
Scenario: Strong uptrend on Volatility 75, price at 46,000, just broke 45,500 resistance Analysis: Momentum will continue, price will not revert into original range Strategy:
- Contract: Ends Outside
 - High Barrier: 45,800 (below current price)
 - Low Barrier: 45,200
 - Duration: 10 minutes
 - Logic: Set range BELOW current price, betting momentum prevents reversion
 - Payout: 75%
 
Strategic Timing: Ends Between works best on longer durations (15-30 min) when volatility has time to normalize. Ends Outside works best on shorter durations (5-15 min) when breakout momentum is fresh and strong.

How to Execute on Deriv Trader
📋 Complete Execution Workflow
Step 1: Select Contract Type
- Navigate to Trade → Options → Digital Options
 - In contract type dropdown, select "In/Out"
 - Then select "Ends Between/Ends Outside"
 
Step 2: Set the High Barrier
- Locate "High barrier offset" input field
 - Enter positive value (e.g., +500)
 - Platform calculates: High Barrier = Current Price + 500
 
Step 3: Set the Low Barrier
- Locate "Low barrier offset" input field
 - Enter negative value (e.g., -500)
 - Platform calculates: Low Barrier = Current Price - 500
 - This defines the complete price window
 
Step 4: Visual Verification
- Platform draws two horizontal lines on chart:
- Blue line: High Barrier
 - Red line: Low Barrier
 
 - Verify visually: Does this range match your strategy?
 - Check range width: High Barrier - Low Barrier = Total Range
 
Step 5: Set Duration and Stake
- Choose expiry: Time-based (5 min, 15 min, 30 min, 1 hour)
 - Enter stake amount (e.g., $10)
 - Platform displays:
- Exact High Barrier price
 - Exact Low Barrier price
 - Ends Between payout %
 - Ends Outside payout % (inverse relationship)
 
 
Step 6: Choose Contract Direction
- Click "Buy Ends Between" (betting price ends inside range)
 - OR
 - Click "Buy Ends Outside" (betting price ends outside range)
 
Step 7: Monitor and Wait
- Trade appears in "Portfolio" tab
 - Price can cross barriers during trade (this is OK!)
 - Only the final tick (Exit Spot) determines outcome
 - At expiration, platform automatically settles
 
Example Strategy: End-of-Session Mean Reversion
💡 Real Strategy Walkthrough
The "End-of-Session Mean Reversion" Strategy (Ends Between):
Objective: Exploit end-of-session volatility drop and mean reversion tendency.
Setup:
- Time: 4:45 PM EST (15 minutes before NY close at 5:00 PM)
 - Asset: Volatility 75 Index
 - Current Price: 45,250
 - Market Condition: Volatile day, price ranged 44,500-46,000, currently mid-range
 - Analysis: End-of-session traders close positions, volatility drops, price reverts to mean
 
Execution:
- Contract: Ends Between
 - High Barrier offset: +750 (Barrier at 46,000)
 - Low Barrier offset: -750 (Barrier at 44,500)
 - Range width: 1,500 points (encompasses day's range)
 - Duration: 15 minutes (expires at 5:00 PM, exactly at close)
 - Stake: $15 (1.5% of $1,000 account)
 - Payout: 62% ($24.30 return, $9.30 profit)
 
Logic:
- Session close creates natural consolidation (traders flatten positions)
 - Range encompasses full day's movement with small buffer
 - 15-minute duration aligned with natural session-close timeline
 - Medium-wide range (1,500 points) provides safety buffer
 - Implied probability: 1 / 1.62 = 61.7% (market calculates 62% win rate)
 - Your edge: Historical data shows 72% of session closes end within day's range on Volatility 75
 
Risk Management:
- Only use during confirmed session-close windows
 - Skip if major news scheduled after close
 - Maximum 1-2% account risk
 - Stop strategy after 2 consecutive losses (market behaving abnormally)
 
Expected Outcome:
- Win Scenario: Price settles anywhere between 44,500-46,000 (most likely 44,800-45,700)
 - Loss Scenario: Late spike beyond range (rare at session close)
 - Long-term: 72% win rate at 62% payout = +7.6% edge per trade

Summary
Key Principles (0/5)
Common Mistakes and How to Avoid Them
⚠️ Top 5 Mistakes
| Common Mistake | Why It Happens | How to Avoid It | 
|---|---|---|
| Path Confusion | Confusing this contract with Stays Between/Goes Outside. Traders panic when price touches barrier mid-trade, thinking they lost. | Remember: Price can touch barriers during trade; only the Exit Spot at expiry matters. Do not close early in panic. | 
| Narrow Range Trading (Ends Between) | Setting barriers too close on volatile indices. Price easily escapes at expiry despite consolidation mid-trade. | For Ends Between on Volatility 75+, use minimum ±400 point range. Give ample room for expiry volatility. | 
| Wide Range Trading (Ends Outside) | Setting barriers too far expecting massive breakout. Price moves but not far enough to reach. | For Ends Outside, set barriers just beyond realistic breakout targets. Use recent volatility as guide. | 
| Ignoring Time-Volatility Decay | Using short durations for Ends Between (volatility has not declined yet). | Ends Between needs 15+ minute durations for volatility to normalize. Use Ends Outside for short durations instead. | 
| Trading Through News | Holding Ends Between through major news event. Massive spike destroys the range assumption. | Close Ends Between positions before major news (NFP, CPI, Fed). News-driven spikes invalidate consolidation thesis. | 
Compare With Other Contracts
📊 Range Contract Comparison
| Feature | Ends Between/Outside | Stays Between/Goes Outside | Higher/Lower | 
|---|---|---|---|
| Barriers | Two (High & Low) | Two (High & Low) | One (Custom Barrier) | 
| Win Check | Expiry Spot Only | Any point in Path | Expiry Spot Only | 
| Trading Concept | Final destination price location within/outside range | Range survival or range breach during contract | Final destination side of single barrier | 
| Path Matters? | ❌ No (expiry-only) | ✅ Yes (instant settlement) | ❌ No (expiry-only) | 
| Mid-Trade Touch | Allowed (no impact) | Instant loss/win | Allowed (no impact) | 
| Best For | Predicting expiry volatility state | Predicting continuous path behavior | Predicting price-target distance | 
| Forgiveness | High (can recover from mid-trade errors) | None (instant settlement) | Moderate (single barrier) | 
Decision Framework: Predicting expiry consolidation? → Ends Between. Predicting expiry breakout? → Ends Outside. Predicting continuous path containment? → Stays Between/Goes Outside. Predicting single price target? → Higher/Lower.
Try It on Demo (Challenge Task)
🎯 Your LeTechs Demo Task: Test Expiry-Only Settlement
Objective: Experience how path-independence works and understand that only Exit Spot matters.
Instructions:
- Switch to Demo Account on Deriv platform
 - Select Volatility 75 Index
 - Place Ends Between Trade:
- High Barrier: +300 points
 - Low Barrier: -300 points
 - Duration: 5 minutes
 - Stake: $10
 - Note the payout % (likely 80-95%)
 
 - Observe During Trade:
- Watch the price touch or cross your High or Low Barrier mid-trade
 - Notice: The contract remains active (does NOT instantly settle)
 - Price can move back inside the range
 
 - At Expiration:
- Platform checks ONLY the final tick (Exit Spot)
 - If Exit Spot is inside range: Win (even if price touched barriers mid-trade)
 - If Exit Spot is outside range: Loss
 
 
Reflect:
- If the price had stayed outside the barriers for 4 minutes, then moved back inside in the last second, would the Ends Between contract have won or lost?
- Answer: Won! Only Exit Spot matters.
 
 - This is why Ends Between is forgiving of mid-trade volatility spikes
 
Key Lesson: Expiry-only settlement is forgiving. Do not panic when price touches barriers mid-trade. Trust your expiry analysis, not mid-trade price action.
Quiz
What is the key difference between Ends Between/Ends Outside and Stays Between/Goes Outside?
Answer:
Ends Between/Outside contracts are expiry-dependent (only Exit Spot matters). Stays Between/Goes Outside contracts are path-dependent (instant settlement on barrier touch). This fundamental difference changes the entire risk profile and strategy approach.
You trade Ends Between with range 44,500-45,500. During the trade, price spikes to 46,000, then returns to 45,200 by expiry. What happens?
Answer:
You win! Ends Between only checks Exit Spot at expiration. Price at 45,200 is inside the range (44,500 to 45,500). The mid-trade spike to 46,000 is completely irrelevant. This is the forgiveness of expiry-only settlement.
For Ends Between contracts, what happens to payout as you widen the range?
Answer:
Payout decreases as range widens. Wider range = higher probability price stays inside = lower payout. Example: 400-point range pays 95%, but 1,500-point range pays only 55%. Inverse relationship: probability up, payout down.
