Answer:- Sometimes You listen, brokers provide their platform for trading to trader, investor etc. their aim to earn money and have commission .I am saying exactly that one called spread in forex market.
It is mainly the difference between bid price and ask price.
Suppose their current market price is bid $1.1244 and ask $1.1248
Spread is $1.1244-$1.1248=0.0004
The mainly the broker’s commission and all buttering are included in spread
