What is Liquidation
Liquidation — forced closure of a trading position by an exchange when trade losses reach the size of your collateral (margin). Occurs when trading with leverage when price moves against you.
How Liquidation Happens
Example with 10x leverage:
Capital (margin): $1,000
Position: $10,000 (long BTC at $50,000)
BTC amount: 0.2
Liquidation at ~10% drop:
├── BTC drops to $45,000
├── Loss: $1,000 (100% of margin)
├── Exchange closes position
├── You lose $1,000
└── Position no longer exists
Calculating Liquidation Price
Formula (Simplified)
For long:
Liq. price = Entry price × (1 - 1/Leverage + Maintenance Margin)
For short:
Liq. price = Entry price × (1 + 1/Leverage - Maintenance Margin)
Examples
| Leverage | Move to liquidation (long) |
|---|---|
| 2x | ~-50% |
| 5x | ~-20% |
| 10x | ~-10% |
| 20x | ~-5% |
| 50x | ~-2% |
| 100x | ~-1% |
Types of Liquidation
Partial Liquidation
With cross margin:
├── Part of position closed first
├── To reduce risk
├── If price continues falling
└── Fully closed
Full Liquidation
With isolated margin:
├── Entire position closed immediately
├── Lose allocated margin
└── Other funds are safe
Margin: Isolated vs Cross
| Margin Type | On Liquidation |
|---|---|
| Isolated | Lose only position margin |
| Cross | Lose entire account balance |
Recommendation:
├── Beginners → isolated margin
├── Experienced → cross with caution
└── Always → stop-losses
How to Avoid Liquidation
1. Low Leverage
Instead of 20x → use 2-3x
├── More room for movement
├── Liquidation at -33% instead of -5%
└── Less stress
2. Stop-Loss
Always set stop before liquidation:
Entry price: $50,000
Leverage: 10x
Liquidation price: $45,000
Stop-loss: $47,000
├── Loss: 30% of margin
├── NOT 100%
└── Capital remains for next trade
3. Smaller Position Size
2% rule:
├── Risk per trade: max 2% of capital
├── With $10,000 capital
├── Max loss: $200
└── Even with liquidation — tolerable
4. Adding Margin
If position goes negative:
├── Can add margin
├── Pushes liquidation further
├── But increases potential losses
└── Use carefully
Cascade Liquidations
Dangerous market phenomenon:
Chain reaction:
1. Price falls
2. Liquidations trigger
3. Liquidations sell asset
4. Price falls more
5. More liquidations
6. Flash crash
Historical Examples
- March 2020: $1.6B liquidations in one day
- May 2021: $8B liquidations in one day
- FTX crash 2022: mass liquidations
Liquidation and DCA
For DCA strategy, liquidation doesn't exist as a risk:
Why DCA is Safe
DCA on spot:
├── No leverage → no liquidation
├── Own real asset
├── Can hold forever
├── Max loss = asset decline
└── NOT 100% like with liquidation
Comparison Example
Investment: $1,000
With 10x leverage (futures):
├── 10% drop → liquidation
├── Loss: $1,000 (100%)
└── No asset
DCA on spot:
├── 10% drop → $100 loss
├── Keep holding
├── 50% drop → $500 loss, but...
├── On recovery → profit
└── Asset is still yours

Signs of Imminent Liquidation
Red flags:
├── Margin ratio close to 100%
├── Exchange notifications
├── Unrealized loss growing
└── Price approaching liquidation
What to Do When Liquidation Threatens
- Close position manually — lock in loss
- Add margin — if confident in reversal
- Reduce position — close part
- Nothing — if ready to lose margin
Important: The best way to avoid liquidation is not to trade with leverage. For long-term accumulation, use DCA on spot. There's no liquidation risk, and you own a real asset you can hold as long as you want.
