I'm very interested to open an account with one of this three firms ( CMC , REALTIME FOREX , CMS ). Before deciding to open the account however, I have a technical question that's important for me. Please give me a precise answer, not vague. I need to know,please from real account customer of these firms how many seconds exactly pass between the click for buy/sell order and the arrival of the executed confirmation of the fill. The question refers to normal conditions of market and in fast marker conditions. Thank you.
