Exness
Exness's two genuine standouts are instant withdrawals and $4 trillion in monthly volume — both verifiable. The unlimited leverage claim is real but applies only to accounts under $1,000 equity on offshore entities. For Australian traders, note that the ASIC entity caps leverage at 1:30 — the unlimited leverage applies only under offshore entities.
BlackBull
BlackBull Markets was founded in New Zealand — a neighbouring jurisdiction with strong regulatory credibility. FMA-regulated with true ECN execution, 26,000+ instruments and one of the broadest platform selections in the industry. Leverage up to 1:500. Most international clients trade under the Seychelles entity — worth noting before opening an account.
AvaTrade
AvaTrade holds a direct ASIC license in Australia — some of the strongest retail trader protections available in the region. For Australian traders who want genuine regulatory depth alongside a broad instrument range, copy trading tools and AvaProtect trade insurance, it's one of the more complete regulated options on the market.
What Spreads Really Mean in Trading
At first glance, spreads look simple: it’s just the difference between the buy (ask) and sell (bid) price, everybody knows that. But in practice, this small gap is one of the most important cost drivers in trading. Every time you open a position, you’re effectively starting slightly negative—and how big that gap is can shape your long-term performance.
Fixed vs Variable Spreads
Not all spreads behave the same way. Understanding the difference can help you avoid surprises:
Fixed spreads stay constant regardless of market conditions. They offer predictability, but are usually set higher to compensate for that stability.
Variable (floating) spreads change based on liquidity and volatility. They tend to be tighter during active market hours, but can widen significantly during low liquidity or high-impact events.
Standard vs Raw (ECN) Accounts
The type of account you use directly affects how spreads are structured:
Standard accounts include the broker’s markup within the spread. What you see is what you pay—no separate commission, but generally wider spreads.
Raw or ECN accounts offer spreads closer to market prices (sometimes near 0.0 pips), but charge a fixed commission per trade.
Depending on your trading frequency and strategy, one model may end up being cheaper than the other.
When Spreads Are Tightest (and Widest)
Spreads are not static—they move with the market:
Tighter spreads usually occur during periods of high liquidity, such as when major trading sessions overlap.
Wider spreads often appear during low activity periods or around major news releases, when uncertainty increases.
This is why the average spread is often more relevant than the minimum spread advertised.
Different Assets, Different Spreads
Not all markets are created equal:
Major forex pairs tend to have the lowest spreads due to high liquidity.
Minor and exotic pairs usually come with wider spreads.
Other assets like indices, commodities, or crypto can vary widely depending on demand and volatility.
Understanding this helps set realistic expectations when comparing brokers.
