You open a trading platform. You see two prices for EUR/USD: 1.0850 and 1.0852. The difference between them is two pips. That difference has a name — the spread. And it is the single most consistent cost you will pay as a trader. Understanding spreads is the difference between knowing your true entry price and wondering why your trades never seem to perform as expected.
Trading involves risk. Binary options and forex trading involve substantial risk of losing your capital. This guide is for educational purposes only. Never trade money you cannot afford to lose.
What Is a Spread in Trading?
A spread is the difference between the bid price (what buyers are willing to pay) and the ask price (what sellers are asking for). In simple terms: the bid is what you sell at, the ask is what you buy at. The spread is the cost of entering the trade.
Think of it like a currency exchange booth at the airport. They post two rates: one for buying dollars (lower) and one for selling dollars (higher). The difference is their profit. Brokers work the same way — the spread is how they make money on each trade.
Here is what most beginners miss: You start every trade at a small loss equal to the spread. If the spread is 2 pips, your trade needs to move 2 pips in your favor just to break even. That is why tight spreads matter — especially for short-term traders who capture small price moves.
Bid vs Ask: The Two Prices You Need to Know
Bid Price — What You Sell At
The bid price is the highest price a buyer is willing to pay. When you sell a currency pair, you sell at the bid price. If EUR/USD bid is 1.0850, that is what you get when you sell.
Ask Price — What You Buy At
The ask price is the lowest price a seller is willing to accept. When you buy a currency pair, you buy at the ask price. If EUR/USD ask is 1.0852, that is what you pay.
The Spread Formula
Spread = Ask Price − Bid Price. If EUR/USD ask is 1.0852 and bid is 1.0850, the spread is 0.0002, or 2 pips. On a standard lot ($100,000), that is $20 — your cost to open and close one trade.
Types of Spreads in Forex and Binary Options
Fixed Spread
The spread stays the same regardless of market conditions. A broker might offer a fixed 2-pip spread on EUR/USD whether the market is quiet or volatile. Predictable, but usually wider than variable spreads during calm conditions. Common in market maker broker models.
Variable (Floating) Spread
The spread changes based on market liquidity and volatility. During the London session (high liquidity), EUR/USD spreads can be as low as 0.1 pips on ECN accounts. During news events, they can widen to 5-10 pips or more. Common in ECN/STP broker models.
Zero Spread Accounts
Some brokers offer accounts with spreads from 0.0 pips. Sounds perfect — but they charge a commission instead. Typically $3-$7 per lot per side. Zero spread accounts are best for scalpers and high-volume traders who prefer predictable costs over variable spreads.
Why Spreads Matter for Binary Options Traders
Binary options work differently from forex. Most binary platforms do not show a traditional bid/ask spread. Instead, the cost is built into the payout percentage. A platform offering 85% payout on a $10 trade pays $8.50 profit on a win — the $1.50 difference from a fair 100% payout is effectively the spread.
But some binary platforms now offer forex-style trading with variable spreads. If you trade binary options on a platform like IQ Option or Olymp Trade, the spread applies to forex pairs just like a regular broker. A 2-pip spread on a $10 binary trade with a 5-minute expiry can eat 5-10% of your potential profit.
Real-World Example: Spread Cost on a Forex Trade
You open an account with a broker offering 1.0 pip spread on EUR/USD (standard account). You trade 1 mini lot ($10,000). You buy at 1.0852 and the spread is 1.0 pip. Your trade starts 1 pip in the hole — that is $1 on a mini lot.
Now compare with an ECN account offering 0.2 pip spread but $3.50 commission per side. Same mini lot trade: 0.2 pip spread = $0.20 cost, plus $3.50 commission = $3.70 total. On the standard account: 1.0 pip spread = $1.00 cost, no commission. The ECN account is more expensive for this trade size.
But on a full standard lot ($100,000): ECN cost = 0.2 pips ($2) + $7 commission = $9. Standard account cost = 1 pip ($10). At higher volumes, ECN becomes cheaper. That is why high-volume traders use ECN accounts and beginners often prefer fixed spread accounts.
Common Mistakes Beginners Make with Spreads
1. Ignoring the spread when calculating targets. If you set a 20-pip take-profit but the spread is 2 pips, your actual target from entry is 18 pips. Always include the spread in your risk-reward calculation.
2. Choosing a broker based on spread alone. A broker with 0.0 pip spreads but $7 commission might cost more than a broker with 1.0 pip spread and zero commission — depending on your trade size. Always calculate total cost, not just spread.
3. Trading during high-spread periods. Spreads widen during news events, market opens, and low-liquidity sessions (Asian session for EUR/USD). A pair that normally has 1 pip spread can spike to 5 pips during a Fed announcement. Check the economic calendar before entering.
4. Forgetting swap costs in forex. The spread is your entry cost, but swap (overnight financing) is your holding cost. A trade held for several days can accumulate swap costs that exceed the initial spread — especially on pairs with large interest rate differences.
Spread Comparison Table
| Account Type | Typical Spread (EUR/USD) | Commission | Best For |
|---|---|---|---|
| Standard (Fixed) | 1.0 – 2.0 pips | None | Beginners, small accounts |
| Raw/ECN (Variable) | 0.0 – 0.3 pips | $3-$7 per lot/side | Scalpers, high volume |
| Islamic (Swap-Free) | 1.5 – 2.5 pips | None | Traders avoiding swap |
| Binary (Fixed payout) | Built into payout | None visible | Binary options traders |
FAQ
What is a good spread for forex trading?
For major pairs like EUR/USD, a spread under 1 pip is good. Under 0.5 pips is excellent (usually ECN accounts). For minor pairs and exotics, 2-5 pips is normal. If your broker consistently offers spreads above 2 pips on EUR/USD, you are paying too much.
Do binary options platforms have spreads?
Most binary options platforms do not show a spread — the cost is embedded in the payout percentage. A platform offering 85% payout on a $10 trade effectively keeps $1.50 as its fee. Some hybrid platforms (like IQ Option) show a spread on forex pairs traded in their CFD mode.
When are spreads the lowest?
Spreads are lowest during peak liquidity hours: the London session (8 AM – 12 PM GMT) for EUR/USD and GBP/USD, and the overlap between London and New York (1 PM – 5 PM GMT) for all major pairs. Avoid trading during the first hour after major news events.
