The Alpari Pro ECN account represents the highest deposit requirement and tightest recorded spread range among the four Alpari accounts in Broker Alarab data. Spreads range from 0.0–0.3 pips with a recorded average of 0.2 pips, commission is $4 per lot, the minimum deposit is $500 and orders use Market Execution. We categorize the account for professional traders. The figure most likely to attract attention is the spread starting from 0.0 pips, but that number requires proper context. The recorded range extends to 0.3 pips, the average is 0.2 pips and a separate $4 per-lot commission also applies. A zero starting spread therefore does not mean zero trading cost and should not be used independently to evaluate the account. Compared with ECN, Pro ECN reduces the recorded spread range from 0.4–0.9 pips to 0.0–0.3 pips, while commission increases from $3 to $4 per lot and the minimum deposit rises from $300 to $500. This comparison matters because moving to Pro is not simply a free pricing improvement; three components change simultaneously: spread, commission and capital requirement. The difference becomes even larger when compared with Standard. Standard relies on 1.2–1.7 pip recorded spreads without a separate commission and has a $100 minimum deposit, while Pro ECN uses a substantially tighter range with a separate commission and higher deposit requirement. Pro ECN therefore serves a different search intent centered on professional trading, tight spreads and advanced account pricing rather than competing with Standard for the same queries.
