what is spread in forex trade ?

Spread is a trading fee which you dont see stated in your trading account statement because the prices of the instruments you trade have been inflated by the broker

spread is simply the difference between the bid (sell) price and the ask (buy) price of a currency pair.

It's basically the broker's main fee, tighter spreads = lower cost for you. Always check it before trading.

Spread is like a gate fee, you must pay it before you enter the market

The spread is essentially the cost you pay to enter any trade—it acts as your built-in entry fee every time you participate in the market. Because of this, the smaller the spread, the better it is for the trader, as it reduces your initial cost and allows your trade to move into profit more quickly. Wider spreads, on the other hand, increase your trading cost and can make it harder to achieve consistent profitability, especially for short-term traders.
