The MT4 platform allows 9 different time frames per chart. The time frames start with an M, H, D, W, and MN. These stand for Minutes, Hours, Days, Weeks, and Months. This is then followed by the time intervals of 1, 5, 15, 30, and 4. You can find these 9 time frames at the top toolbar area of MT4, just above that charts, showing as M1, M5, M15, M30, H1, H4, D1, W1, and MN.
