Not every currency pair behaves the same way, and the difference isn't random โ it comes down to how much real trading volume flows through a pair, which affects everything from spread cost to how sharply price can move.
Major pairs
The most heavily traded pairs in the world, always involving the US dollar paired with another major economy's currency: EUR/USD, GBP/USD, USD/JPY, USD/CHF, AUD/USD, USD/CAD, NZD/USD. These carry the most real trading volume of any pairs โ which typically means tighter spreads (lower cost to trade) and generally more predictable behavior around real support and resistance levels, simply because so many participants are watching and reacting to the same price.
Minor pairs (cross pairs)
Pairs between two major economies that don't include the US dollar at all โ EUR/GBP, EUR/JPY, GBP/JPY, AUD/NZD, and similar combinations. These still carry real, meaningful volume, but less than the majors. Spreads tend to be a bit wider, and price can occasionally behave less cleanly around technical levels simply because there's less liquidity absorbing every move.
Exotic pairs
A major currency paired with a currency from a smaller or emerging economy โ USD/TRY (Turkish lira), USD/ZAR (South African rand), USD/MXN (Mexican peso), and similar. These carry meaningfully less trading volume, which usually means wider spreads, and price can move much more sharply and unpredictably โ sometimes driven by a single piece of local political or economic news that would barely register for a major pair.
Why this actually matters for how you trade
Cost. Wider spreads on minor and exotic pairs mean a real, direct cost difference before you've even judged the trade correctly โ the same size stop loss effectively costs more in a wider-spread pair.
Predictability of technical levels. Support and resistance and other structure-based ideas tend to work more reliably on pairs with deep, consistent liquidity โ the majors โ simply because more real participants are watching and reacting to the same levels. On a thin, exotic pair, a level can break cleanly on genuinely low volume that wouldn't move a major pair at all.
News sensitivity. A single local news event can move an exotic pair far more violently than it would move a major, since there's less overall volume to absorb the reaction.
Where SonaPips fits in this picture
SonaPips deliberately covers GBP/USD and EUR/USD โ both majors โ plus Gold, which trades with major-pair-level liquidity despite not being a currency pair itself. This isn't an accident: majors and Gold are where the confirmation-based approach this whole site teaches actually works most reliably, precisely because of the deep liquidity discussed above.
Starting with majors isn't a limitation โ for most traders, especially while still building real experience, it's genuinely the more forgiving, more predictable place to learn.
