For example:
The value of 1 point in foreign exchange transactions is 10 USD, which is fixed. Transaction cost is only related to the number of transactions.
1. If the agent doesn't add commission, you need to buy 1 lot cost =1USD * price difference of currency pair * 1 lot;
Take the spread between Europe and America (EUR/USD) as an example, the transaction cost of 1 lot =1USD * 2 points * 1 lot = USD 20;
2. The same is true for agency plus commission. For every 1 point commission, you will increase 1 point on the basis of the original spread of the currency pair;
Similarly, taking the price difference between Europe and America as an example, if the agent adds a commission of 2 points, the transaction cost of 1 lot is equal to 10 USD *(2+2)* 1 lot =40 USD.
