外汇公司的点差 varies widely depending on the company, currency pair, and market conditions. Tight spreads are typically around 0.1-0.2 pips for major currency pairs like EUR/USD during normal market conditions. Wider spreads, ranging from 1-3 pips or more, are common for less liquid currency pairs or during volatile market conditions.
You should compare live spreads from different brokers to find the best deals. Also, brokers may offer different types of accounts with varying spreads, such as a standard account with wider spreads and a premium account with tighter spreads.
Keep in mind that spreads are not the only cost associated with forex trading. Commissions, swaps (overnight financing fees), and other charges can also affect your profitability. Make sure you understand all the costs involved before you start trading.
