Forex 101 · Day 3: Spread — the hidden cost you pay every time you open a trade

In the first two days, we covered pips and currency pair quotes. Today we’ll break down the piece that new traders most easily overlook: the spread.

One-sentence definition:
Spread = Ask price − Bid price.
For an EUR/USD quote of 1.0850 / 1.0851, the spread is 1 pip (0.0001). For major currency pairs, the spread is commonly 1–3 pips.

Why does it matter?
The spread is a cost created the instant you open a position—you haven’t made any profit yet, and it already takes a chunk out of your account. With the same strategy, a 0.2-pip account versus a 1.5-pip account can differ by several times in cost after high-frequency trading.

Three things to remember:
① The smaller the spread, the better: Major pairs are usually 1–3 pips; less-traded (minor) currencies often have wider spreads. Don’t only look at the exchange rate—calculate cost.
② During major data releases, the handover between Europe and the U.S., and in the early-morning hours, spreads widen—so opening trades costs you more.
③ Don’t get too excited about “0 spread”: Many brokers switch to fixed commission fees. You need to check the total bill—0 spread ≠ free.

Quick note about crypto: The BTC/USDT spot market also has a bid/ask spread (the gap between Bid and Ask). Before you place an order, weigh the implicit cost.

Title alternatives (5 angles):
1. Question-based: Why can spreads on the same platform be so different?
2. Reveal-based: Every time you open a trade, you first lose the money from this spread
3. Value-based: 0.2 pip vs 1.5 pips — a 7x difference in high-frequency trading costs
4. Controversial: Are “0 spread” accounts really free?
5. Suspense-based: Why does the spread suddenly widen right after major news hits?

Tomorrow we’ll cover: Trade direction — going long or going short. If your direction is wrong, the spread loss accelerates.
