The importance of the trading platform server time is often overlooked by traders and even brokers. It’s true the time zone offset doesn’t really matter as far as trade execution or order history is concerned but when charts that are used for technical analysis are affected that matters. In MT4 the server time offset directly impacts how candlesticks are produced on the daily charts and that directly affects analysis produced using daily charts. You see the end of the trading day is in alignment with a time known as New York Close. Please don’t get confused that doesn’t mean that trading platforms (or charts) should be in alignment with New York time. What it does mean is that the trading day needs to end when the trading session ends in New York. Therefore using best practice the MT4 server time should show it is Friday midnight when it is 17:00 in New York on a Friday. The reason this is so important is because we often use daily candlesticks for analysis. Using an MT4 platform with the correct New York Close time zone will result in 5 daily candlesticks per week, from Monday to Friday. This is because when the Monday trading session opens it will be exactly midnight as Monday morning begins. Similarly as the Friday trading session closes it will be midnight on Friday night. Any other time zone offset will result in 6 daily candlesticks even though there are only 5 trading days in the week. For example if an MT4 server is set to GMT/BST like it is for certain brokers it means the trading session will begin on Sunday at 22:00 GMT/BST and close on Friday at 22:00 GMT/BST. With this configuration that means there will be a daily candlestick shown for Sunday (which lasted 2 hours) and the Friday candlestick will only be for a 22 hour day. This incorrect time zone offset means analysis on the daily charts become inaccurate, which is a big deal.
