+ REX OscillatorSo, what is the REX oscillator, you might be asking yourself.
"The Rex oscillator is an indicator that measures market behavior based on the relationship of the close to the open, high and low values of the same bar. A big difference between the high and close on a bar indicates weakness, and wide disparity between the low and close indicates strength. The difference between open and close also indicates market performance."
The True Value of a Bar (TVB) gives an indication of how healthy the market is. A negative close and a positive TVB (or vice versa) is an indication of the market building strength on the opposing side of the trend. The Rex oscillator is a moving average of the TVB value with the specified period.
I first came across this watching one of many No Nonsense Forex videos. Mostly, from comments I've read, it is used as an exit indicator for people who trade with a system similar or identical to the one VP espouses in his NNFX blog. I think it's perfectly apt to use as an entry indicator as well, or even as both, perhaps, depending on the moving average you chose to apply to the TVB.
There are a few other versions of this on tradingview, but I thought I'd make an updated version. Added Donchian Channels because I like the idea of a dynamic sort of overbought/sold area. I left out the basis because the indicator pivots around a center line, and has a signal line as well. A basis line just seemed like too much, and would likely not be very useful.
The additional usual things that I incorporate into my indicators are included here: optional candle coloring, alerts, and probably a too large selection of moving averages.
Credit to Nemozny for the FRAMA calculation. I may add that to other indicators I have.
