How much do brokers charge for a trade?
Some brokers will charge you a flat fee for each trade, regardless of the trading size. In other words, you can trade as little as €/$/£ 5 or as much as €/$/£ 1,000,000, the trading costs remain the same.
Other brokers might charge you a percentage of your trade, for instance, 2.5% of the trading sum. You need to think about what works best for you, but in general if your trading value is a couple of €/$/£1,000s, a flat fee is likely to be the cheapest option.
