EA Studio was updated to calculate the broker's commissions.

You set the commission in the Data Export script code:

See your broker's website for details on how it applies the commission. Generally, the ECN brokers apply a flat dollar commission per entry and exit per lot. If, for example, your broker has a commission of 8 USD per open and per close, you have to set 16 in the script code.

Another easy way to see the exact commission is to open and close 1 lot position on a Demo account. If you enable the "Commission" column in the "Account History" tab. 

EA Studio shows the current market commission on the Report page.
