There's no gainsaying that the numerous indicators on platforms exist for the reason that each of them is used by one trader or the other. There are done I would find utterly useless but I also see certain traders mention them as useful. I guess it's the "one man's meat is another's poison" type of thing. Having so much indicators on platforms often complicates trading. The logic is to keep it simple. I like to use and depend heavily on line indicators of Support & Resistance, Pivots and Trendlines and then mix with rsi and MA for crosses. Keep it simple. Trading shouldn't be complicated.
