5 Betfair Beginner Mistakes (And How to Avoid Them)

Written by
Traderline Team
Every Betfair trader makes mistakes. The difference between success and failure is learning from them quickly. These are the 5 most expensive beginner mistakes - and exactly how to avoid them.
Top Mistakes to Avoid
- Not calculating liability before laying
- Trading low-liquidity markets
- No stop-loss strategy
- Overtrading and chasing losses
- Using stakes too large for bankroll
- Not tracking trades for learning
Mistake #1: Not Calculating Liability
The Error: Laying without knowing your maximum loss.
Why It's Costly: Liability can be 10x your stake at high odds. One bad trade can wipe out weeks of profits.
Trader lays £20 at 15.0 thinking they'll win £20.
Reality: Liability is £280. If the selection wins, they lose £280, not £20.
Lesson: Always calculate liability BEFORE placing lay bets.
Solution:
- Use Traderline's automatic liability bet mode
- Start with low odds (1.50-3.00) while learning
- Always stick to liability bet mode when laying
Mistake #2: Trading Low-Liquidity Markets
The Error: Trading niche sports or lower leagues with little money in the market.
Why It's Costly:
- Wide spreads eat your profits
- Can't exit when you need to
- Odds swing wildly on small bets
- Difficult to match bets
Liquidity Check
Before trading ANY market, check traded volume:
- ✅ £100K+ = Safe for beginners
- ⚠️ £20K-100K = Proceed with caution
- ❌ <£20K = Avoid until experienced
Solution:
- Stick to Premier League, Grand Slams, major racing
- Check traded volume before entering
- Avoid lower leagues and niche sports
- Higher liquidity = easier trading
Mistake #3: Overtrading and Chasing Losses
The Error: Making too many trades or trying to win back losses immediately.
Why It's Costly:
- Emotional decisions replace strategy
- Commission adds up quickly
- Fatigue leads to more mistakes
- Losses compound
Solution:
- Set maximum trades per day (5-10 max)
- Take breaks after losses
- Focus on quality over quantity
- Track win rate - if dropping, trade less
Mistake #4: Stakes Too Large for Bankroll
The Error: Risking 10-20% of bankroll on single trades.
Why It's Costly: One bad run wipes out your entire bankroll. No recovery possible.
Bankroll Management
Safe staking:
- Risk 1-2% per trade
- £500 bankroll = £5-10 stakes
- £1000 bankroll = £10-20 stakes
Dangerous staking:
- Risk 10%+ per trade
- £500 bankroll = £50+ stakes
- One bad day = bankroll gone
Solution:
- Avoid risking more than 2% per trade
- Start with 1% while learning
- Increase stakes only as bankroll grows
- Protect your capital above all else
- Better not to make money than to lose it
Mistake #5: Not Tracking Trades
The Error: Not recording trades to learn from wins and losses.
Why It's Costly: You repeat the same mistakes without knowing it. No improvement over time.
Solution:
- Analyze every trade (entry, exit, profit/loss, reason)
- Review weekly to identify patterns
- Understand if you're more profitable on specific markets
- Double down on what works
- Eliminate what doesn't
- Use Traderline's automatic trade tracking
Follow this checklist religiously. It prevents 90% of beginner mistakes and protects your capital while you learn.
Start small, trade smart, track everything. Avoid these 5 mistakes and you'll be ahead of most beginners who blow their bankroll in their first couple weeks.
