Now quick and easy — Forex brokers Spreads Comparison table
When spreads widen and quoted higher than advertised
During increased market volatility variable spreads will widen for all dealing desk brokers, which means a trader won't get the lowest spreads advertised by a Forex broker.
However, with ECN brokers clients will have actually lower spreads when activity in the market rises and trading volume increases - during those times variable spreads can drop to 1/10 of a pip = 0.1 pip and even be quoted at zero.
Fixed spreads, although called "fixed", can also be a subject to change.
There are brokers who offer Fixed Guaranteed spreads - such spreads don't change no matter what.
Also traders should note the common practice of widening spreads during weekends, as well as for some Forex brokers - during night hours from Monday to Friday.
