Here are the Double SMA & Triple SMA by Mladen as standalone indicators as well which you can add to your non-repainting Moving Averages collection.

As explained by Mladen:
Saw this idea somewhere and kinda liked it, so here are two indicators for the weekend ...

The idea is similar to DEMA and TEMA but instead of using EMA for calculation SMA is used. Here is a comparison : violet is regular SMA, red is DSMA (double SMA) and blue is TSMA (triple SMA)
