Timeframes

On the other hand, if you are a position trader, who makes 5 trades per year, then the difference amounts to only $10 per year. This is minimal and may very well be outweighed by other factors, such as perhaps higher overnight interest rates in a carry trade strategy, or better customer support or some other factor that gives you more than $10 of value added with the higher spread broker. So neither broker is better or worse, they are just better suited to different styles of trading.
