RSX is a smoothed relative strength line designed to avoid the jagged steps of a plain RSI. The RSX powered JMA indicator draws a 14-bar RSX and adds a Jurik-style moving average over it, then marks the bar where RSX climbs out of 30 or drops out of 70.
This build ships as a compiled .ex4 for MT4 and .ex5 for MT5.

How the RSX Powered JMA Indicator calculates its values
RSX
`InpRsxLength` `14` runs a chain of smoothing filters over price changes. The result reads like RSI but with far less jitter.
JMA line
`InpJmaLength` `9` and `InpJmaPhase` `0.0` shape an adaptive average over RSX. `ShowJMA` draws it.
Exits
A buy prints when RSX climbs above `InpOversold` `30.0`. A sell prints when it drops under `InpOverbought` `70.0`.
Interpreting what you see
RSX above 70 means strong upward pace.
RSX below 30 means strong downward pace.
The goldenrod line lags RSX slightly.
Marks flag exits from the zones.
`InpCooldownBars` `3` spaces same-side marks.
Warm-up needs about forty bars.
Alert channels in this build: popup, push notification, email and sound, one message per closed bar.
Zone exits report once per closed bar. `EnableAlerts` controls them, and the popup is the route set on by default.

Picking a chart for it
A smooth oscillator suits any chart. On the hourly EURUSD screenshot, zone exits come every few days. On M15 they come daily, and on D1 each exit marks the end of a stretched swing.
Where it lets you down
Smoothing still lags the turn.
Zone exits come after the extreme.
JMA settings change the line’s lag noticeably.
Only popups report at first.
Copy the compiled RSX Powered JMA Indicator file into your MQL4/Indicators folder, and the MT5 build into MQL5/Indicators, then restart the terminal and drag it onto a chart. The step-by-step guide with screenshots is at how to install MT4 and MT5 indicators.

FAQ
How is RSX different from a plain RSI?
RSX runs price changes through a chain of smoothing filters before forming the ratio. It keeps RSI’s scale and levels but loses most of the single-bar jitter.
What does InpJmaPhase 0.0 control?
The balance between lag and overshoot in the goldenrod line. Positive values make it follow RSX more closely, while negative values smooth it further at the cost of delay.
Do the marks use the RSX JMA line?
No. Buy and sell marks come from the blue RSX line leaving the zones. The goldenrod JMA line is there to show the smoothed direction.
Why is InpCooldownBars 3 needed on a smooth line?
Even a smooth line can wobble around 30 or 70 for a couple of bars. The cooldown keeps one mark per exit rather than two or three.
Are results guaranteed?
No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the RSX Powered JMA Indicator as one input. Always backtest before trading live.
