Spreads and commissions are the hidden costs that silently erode your trading profits. Many beginner traders focus obsessively on strategy and entry timing while ignoring the fact that they are paying significantly more to trade than necessary. Understanding the true cost of trading—and choosing the right broker and account type—can be the difference between long-term profitability and slow account death. This guide will teach you exactly what you are paying, why it matters, and how to minimize these costs without sacrificing execution quality.
What is the Spread?
The spread is the difference between the bid price (what you can sell at) and the ask price (what you can buy at). It is the primary cost of trading forex and is measured in pips.
How Spread Works in Practice
Example: EUR/USD is quoted at 1.1000 / 1.1002
- Bid (sell price): 1.1000
- Ask (buy price): 1.1002
- Spread: 2 pips (1.1002 - 1.1000)
- If you buy at 1.1002, you are immediately down 2 pips because you can only sell at 1.1000
- Price must move 2 pips in your favor just to break even
Fixed vs. Variable Spreads
| Type | How It Works | Pros | Cons |
|---|---|---|---|
| Fixed Spread | Always the same (e.g., 2 pips on EUR/USD) | Predictable costs, good for news trading | Usually wider than variable spreads during normal hours |
| Variable Spread | Changes based on liquidity and volatility | Very tight during liquid hours (0.5-1 pip) | Can widen dramatically during news or low liquidity (10+ pips) |
| Raw Spread + Commission | Near-zero spread (0.1-0.5 pips) + fixed commission per lot | Lowest cost for active traders, transparent pricing | Commission per trade (usually $6-10 per round turn) |
What is Commission in Forex?
Some brokers charge a commission per trade instead of (or in addition to) the spread. This is common on ECN and Raw Spread accounts.
How Commission is Calculated
- Charged per lot (100,000 units of base currency)
- Typical commission: $3-7 per side (total $6-14 round turn)
- Example: You trade 1 lot EUR/USD with $7 round-turn commission
- You pay $7 total to open and close the trade
- For a 0.5 lot trade, you pay $3.50
Spread vs. Commission: Which is Cheaper?
It depends on your trading style. Let's compare:
| Account Type | EUR/USD Cost (1 Lot) | Who It's Best For |
|---|---|---|
| Standard (2 pip spread) | $20 per round turn | Beginners, small accounts, infrequent traders |
| ECN (0.2 pip spread + $7 commission) | $2 + $7 = $9 per round turn | Active traders, scalpers, anyone trading frequently |
| Premium (1 pip spread) | $10 per round turn | Mid-range option, decent for swing traders |
If you trade more than a few times per week, a raw spread account with commission will save you thousands per year compared to a standard spread account. Do the math.
The True Cost of Trading: Examples
Scalper (10 trades/day, 0.1 lots each)
- Standard account (2 pips): 10 trades × $2 = $20/day = $400/month
- ECN account (0.2 pips + $0.70 commission): 10 trades × $0.90 = $9/day = $180/month
- Savings with ECN: $220/month = $2,640/year
Day Trader (5 trades/day, 1 lot each)
- Standard account (2 pips): 5 trades × $20 = $100/day = $2,000/month
- ECN account (0.2 pips + $7 commission): 5 trades × $9 = $45/day = $900/month
- Savings with ECN: $1,100/month = $13,200/year
Swing Trader (10 trades/month, 1 lot each)
- Standard account (2 pips): 10 trades × $20 = $200/month
- ECN account (0.2 pips + $7 commission): 10 trades × $9 = $90/month
- Savings with ECN: $110/month = $1,320/year
- Note: For swing traders, the difference is smaller—either account works
Spread Variations: When Costs Spike
Times When Spreads Widen Dramatically
| Situation | Normal Spread | Widened Spread | Action |
|---|---|---|---|
| London/NY Open | 0.5-1 pip | 0.5-1 pip (stable) | Best time to trade majors |
| NFP or Major News | 0.5-1 pip | 5-20 pips | Avoid trading or use wide stops |
| Asian Session (quiet) | 0.5-1 pip | 2-4 pips | Expect higher costs on majors |
| Weekends (Friday close) | 1 pip | 10-50 pips | Never hold through weekend unless swing trading |
| Low Liquidity Pairs (exotic) | 10-30 pips | 50-100 pips | Avoid unless experienced |
| Market Holidays | 1 pip | 5-10 pips | Check calendar, reduce size or avoid |
How to Minimize Spread and Commission Costs
- Trade during high liquidity hours (London/NY overlap 8am-12pm EST)
- Focus on major pairs (EUR/USD, GBP/USD, USD/JPY) with tightest spreads
- Use an ECN or Raw Spread account if you trade frequently
- Avoid trading during major news releases unless your strategy specifically targets them
- Never trade exotic pairs (TRY, ZAR, MXN) unless you have a very good reason
- Check your broker's spread history—some brokers widen spreads excessively
- Avoid trading on Sundays when spreads are widest
- For scalpers: Every 0.5 pip of spread saved is significant over time
- Calculate your monthly costs and compare broker options
- Avoid brokers with unusually wide spreads—it is a red flag
Comparing Broker Costs: What to Look For
Questions to Ask Your Broker
- What is the average spread on EUR/USD during London/NY session?
- Is it a fixed or variable spread?
- Do you charge commission? If yes, how much per lot?
- What is the spread during major news events?
- Are there any hidden fees (withdrawal, inactivity, deposit)?
- What is the execution speed (important for scalpers)?
- Can I see historical spread data?
Typical Spread Benchmarks (Major Pairs)
| Pair | Good Spread (ECN) | Average Spread (Standard) | Red Flag (Avoid) |
|---|---|---|---|
| EUR/USD | 0.1-0.5 pips | 0.8-1.5 pips | 3+ pips |
| GBP/USD | 0.3-0.8 pips | 1-2 pips | 4+ pips |
| USD/JPY | 0.2-0.6 pips | 0.8-1.5 pips | 3+ pips |
| AUD/USD | 0.3-0.8 pips | 1-2 pips | 4+ pips |
| EUR/GBP | 0.5-1.2 pips | 1.5-3 pips | 5+ pips |
| GBP/JPY | 0.8-2 pips | 2-4 pips | 6+ pips |
A broker charging 3 pips on EUR/USD when competitors offer 0.5 pips is not competitive—they are quietly stealing your profits. Always compare multiple brokers before choosing.
Conclusão
Spreads and commissions are the cost of doing business in forex, but the difference between a good broker and a bad one can mean thousands of dollars per year. Active traders should strongly consider raw spread accounts with commission instead of standard spread accounts. Always trade during high liquidity hours, focus on major pairs, and avoid news events unless your strategy specifically targets them. Calculate your actual monthly costs based on your trading frequency and compare brokers honestly. A broker offering tight spreads, fast execution, and transparent pricing is worth far more than one offering fancy bonuses or aggressive marketing. Your trading strategy matters, but if you are paying double in spreads compared to the competition, even the best strategy will struggle to overcome that handicap. Choose wisely.
