This script is good to use with Williams %R indicator, to find out when price has bottomed out.
ATR has to be over 90 and Williams %R ( lenght 52 ) has to be over 95 to find out level around which one is good to buy.
You can check back, to see that this worked very well over history. Best way to use this 2 indicators is with DCA ( dollar cost average ), as area where to buy can go a little bit down and up for as long as few months. So dont just jump in, use DCA .
