in futures the premium/discount will keep varying thus exerting unnecessary influence on the chart, that is why must use spot chart which shows the real situation. I use amibroker and have no knowledge of mt4. you can see if it is possible to setupup range bars instead of TF in minutes in the platform. the advantage of range bars is that each candle will complete and new will form only if the price completes the set range and is independant of time, whereas in timeframe setting of say 15 minutes, a new candle forms every 15 minutes irrespective of any price move (for ex. 1000 range in ticks is equal to 10 points and so on, meaning only if the price changes by more than 10 points, a new candle starts)
