RSI TMA Centered Bands Indicator for MT4 and MT5

Written by Dominic Walsh · Published 8 Jul 2026 · Last updated 24 Sep 2026

Fixed 30 and 70 levels ignore how far RSI usually swings. The RSI TMA centered bands indicator wraps RSI in bands built from a centered triangular average and its mean deviation. Because a centered band redraws near the right edge, the marks come from a second band that only looks backward.

This build ships as a compiled .ex4 for MT4 and .ex5 for MT5.

What renders

An RSI line, three band lines and marks in a pane.

`RSI` traces gold at width 2.

`TMA Center` traces deep sky blue.

`Upper Band` traces tomato.

`Lower Band` traces lime green.

`Buy` and `Sell` sit on the RSI line.

• RSI: line, gold, width 2
• TMA Center: line, deep sky blue, width 1
• Upper Band: line, tomato, width 1
• Lower Band: line, lime green, width 1
• Buy: arrow, lime, width 2, arrow code 233
• Sell: arrow, red, width 2, arrow code 234

From price to plot

RSI

`RsiPeriod` `14` uses Wilder’s averaging of closes.

Centered bands

`TmaHalfLength` `10` weights RSI over ten bars each side, 21 in all, and `BandMultiplier` `1.6` sets the width in mean deviations. The newest ten bars redraw.

Signal band

`SignalPeriod` `14` builds a backward-only band. A buy prints when RSI climbs back above its lower edge, a sell when it drops below the upper.

Putting it to work

Gold outside the bands means a stretched reading.

Bands widen when RSI swings harder.

The last ten bars of each band redraw.

Marks come from the hidden backward band.

Marks never repaint.

Guides sit at 30, 50 and 70.

Alert channels in this build: popup, push notification, email and sound, one message per closed bar.

Band re-entries from the backward band report once per closed bar. `EnableAlerts` controls them, and the popup is the single route on when first loaded.

Matching chart to settings

Adaptive RSI bands suit any chart. EURUSD H1 is the reference chart, with re-entries daily. On M15 they come several times a session. On D1 a re-entry marks a pullback within the larger trend.

What to be wary of

The visible bands redraw at the right edge.

Marks may not line up with the drawn bands.

Re-entries repeat often in ranges.

Only a popup reports by default.

FAQ

Why does the TMA Center line redraw?

A centered average uses ten bars on each side of every point. The newest ten bars have no future bars yet, so their values change as new bars arrive.

Do the Buy and Sell marks repaint?

No. They come from a separate band that only uses past bars, set by `SignalPeriod`. Once a mark prints on a closed bar, it stays.

Why might a mark not touch the drawn Lower Band?

The drawn band is centered and the signal band only looks backward, so near the right edge the two differ. The mark always follows the signal band, not the drawn one.

What does BandMultiplier 1.6 control?

The width of both bands, measured in mean absolute deviations of RSI around the centre. Raise it for fewer, more extreme re-entries, or lower it for more frequent marks.

Are results guaranteed?

No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Rsi Tma Centered Bands Indicator as one input. Always backtest before trading live.
