During trending periods every trader would like to have the source of signals to close positions and re-entry if trend continues. The Donchian
channel formed by "lag-free" RSI
which is, basically, RSI
calculated with using Jurik's Moving Average) could be such indicator. Simplest usage is to keep position while RSX
sticks to the channel's bound, and close position when RSX
detaches. Crossings with Oversold/overbought levels and with center line also can provide valuable signals. Don't forget to adjust parameters for your instrument and timeframe.
