Explosive moving average aims to plant bombs on your chart. When it stops growing and starts falling or visa versa, it will put a single bomb on the chart. The bomb will explode after selected number of periods. You can set up an alert for when the bomb is planted.
Explosive MA is a highly volatile indicator. It uses T3 calculation which is a more modern version of TNT calculation. I strongly advise against using Explosive moving average at home, it can be potentially dangerous.
