I personally don't use any indicators except for moving averages. Everything else just clutters the screen and distracts you from the basics.

Try doing a google image search for prop trading and look at what the pros have on their screens.

Instead, most of their focus is on analyzing volume, level 2 quotes (the order book) and Time and Sales data. These are the basics from which they can identify strong support and resistance levels. Everything else is just white noise, and I have yet to see a pro trader using ichimoku
