Magnum Forecast Chart you can get it from magnum4d website http://www.magnum4d.com.my/. From my experience doing analysis of this chart. It's doesn't give you a straight result, you have to find the draw number and what is the number around the draw number. So far, most of the the the number i've arrange compare the actual result (refer to all the result between winning number and forecast number), do contains a winning number but still you need to arrange the number that you think it will come out. Number that i've arrange still in the original form. Smallest to largest.
So, the chart is more to give you a clues of number coming out. The rest is depends how good you can select and arrange the number or compare the number you think you going to buy whether the number is listed or not in the Magnum Forecast Chart.
