You can reduce your spread though by the following:
1. Trade Major Pairs Only
Major pairs have the tightest spreads because of high liquidity:
EUR/USD
USD/JPY
GBP/USD
USD/CHF
Avoid exotics like USD/TRY or USD/ZAR — spreads are huge.
2. Trade During Peak Market Hours
Best time to get lowest spreads:
London session
New York session
London–NY overlap
Spreads widen during:
Asian session
News releases
Low liquidity times (holidays, weekends, rollover)
