//  This is a simple combination of integrated and published scripts, useful 
//  if you don't have a PRO account and want to bypass the 3 indicator limit. 
//  It includes:
//  1) Stoch.RSI
//  2) Relative strenght index
//  3) Stochastic + RSI, Double Strategy (by ChartArt)
//  4) CM_Williams_Vix_Fix Finds Market Bottoms (by ChrisMoody)
//  5) Directional Movement Index (DMI)
//  For more details about 3) and 4) check the original scripts.
