Understanding Spread and Commission Costs

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.

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

• 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

It depends on your trading style. Let's compare:

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.

• 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

• 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

• 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

1. Trade during high liquidity hours (London/NY overlap 8am-12pm EST)
2. Focus on major pairs (EUR/USD, GBP/USD, USD/JPY) with tightest spreads
3. Use an ECN or Raw Spread account if you trade frequently
4. Avoid trading during major news releases unless your strategy specifically targets them
5. Never trade exotic pairs (TRY, ZAR, MXN) unless you have a very good reason
6. Check your broker's spread history—some brokers widen spreads excessively
7. Avoid trading on Sundays when spreads are widest
8. For scalpers: Every 0.5 pip of spread saved is significant over time
9. Calculate your monthly costs and compare broker options
10. Avoid brokers with unusually wide spreads—it is a red flag

• 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?

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.

สรุป

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.
