OANDA FXTrade offers all traders tight spreads with no discrimination. On FXTrade, everyone gets exactly the same spread regardless of account size, trade size or type of customer.

The smart trader pays close attention to spreads, because they are the cost of trading. On a trading platform like FXTrade, there are no other costs or commissions to be paid.
Understanding OANDA's Spreads

* OANDA is committed to offering our traders the tightest spreads possible under normal market conditions.
* During non-standard trading hours (such as the weekend), spreads are widened to reflect illiquidity in the market.
* During periods of high volatility (such as news events), spreads can be temporarily widened to reflect liquidity issues in the market.


Quality of Execution is Important Too!

As a smart trader you know that a tight spread can make a huge difference in your returns. But tight spreads are meaningful only when they are coupled with good execution. Quality of execution determines whether you actually receive tight spreads.

OANDA's FXTrade platform is 100% automated, from market-making through trade execution. This means:

* Real-time executable and transparent pricing
* Instant settlement and deal confirmation
* No dealer intervention
