Rex Oscillator indicator

Hi.

The Rex oscillator 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 (SMA, EMA, WMA or SMMA) of the TVB value with the specified period.

Interpretation

When the Rex Oscillator turns positive in a bearish trend, a reversal is indicated. Likewise, Rex turning negative in a bull market indicates a reversal to the downside.

I stumbled upon a very interesting indicator who would be very useful as an exitindicator. I have looked everywhere but I couldn’t find it ready for PRT.

Here is the mq4-code:
