Non Repaint Solar Wind Indicator: EMA And ZigZag

Written by Dominic Walsh · Published 22 Jun 2026 · Last updated 9 Sep 2026

The non repaint solar wind indicator puts two familiar tools on one chart. A gold EMA runs through price at `MAPeriod` bars, and a ZigZag traces the swing pivots over the top. Arrows fire when a closed bar crosses the EMA, with `Cooldown` bars enforced between one mark and the next.

This build ships as a compiled .ex4 for MT4 and .ex5 for MT5; the screenshots below come from EURUSD H1.

What the Non repaint solar wind Indicator draws on the chart

SolarMA is the gold exponential average running through price.

SolarZigZag is the dodger blue section line joining the swing pivots.

Buy and Sell place lime and red arrows at a closed-bar crossing of the EMA.

TrendDot drops a small aqua marker on every bar, below price when the close leads the EMA and above when it lags.

• SolarMA: line, gold, width 2
• SolarZigZag: section, dodger blue, width 2
• Buy: arrow, lime, width 3, arrow code 233
• Sell: arrow, red, width 3, arrow code 234
• TrendDot: arrow, aqua, width 1, arrow code 159

How the Non repaint solar wind Indicator calculates its values

Seeding and running the EMA

The code seeds the average with a simple mean over `MAPeriod` `21` bars. alpha then takes 2 over the period plus one, and each newer bar takes alpha times close plus the rest of the previous value. Seeding this way avoids the spike a recursive average shows when it starts from zero.

Tracing the ZigZag pivots

A bar becomes a pivot when no bar within `ZZDepth` `12` on either side beats it. `ZZDeviationPts` at `5.0` sets the minimum move in points before a new leg counts. The section line then joins those pivots, which is what gives the classic swing shape.

Firing on a crossing

crossUp needs the previous close at or below the EMA and the current close above it. crossDown mirrors that. `Cooldown` `3` blocks a second mark until three bars have passed. Every test reads completed bars, which is where the non-repaint claim comes from.

How to read the signals

The gold line gives you the direction and the blue sections give you the structure.

A crossing that lands near a fresh ZigZag pivot carries more context than one mid-leg.

TrendDot below price on a run of bars means the close has stayed above the average.

Raise `Cooldown` when marks cluster during a choppy stretch.

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

`EnableAlerts` ships on with `EnablePopup` carrying the message. `EnablePushNotify`, `EnableEmail` and `EnableSound` are off by default, and `SoundFile` names the clip. The guard allows one message per closed bar.

Settings that fit your chart

An average plus a swing tracer suits markets that trend in legs. EURUSD H1 is the reference chart, where `MAPeriod` at `21` covers about a day. On M5 the crossings come fast and `Cooldown` earns its place. On H4 the ZigZag legs span several days and each crossing carries real weight.

When the Non repaint solar wind Indicator fails

ZigZag pivots need `ZZDepth` bars to the right before they confirm, so the newest leg is always provisional.

An average crossing in a range fires in both directions inside a handful of bars.

`Cooldown` hides genuine second signals as readily as it hides noise.

FAQ

What does Cooldown at 3 prevent?

A second mark within three bars of the last one. Crossings often arrive in pairs when price straddles the average, and the cooldown removes the duplicate. Raise it on fast charts where the close keeps flipping either side of the gold line.

How does ZZDepth decide a pivot?

A bar becomes a pivot when nothing within `ZZDepth` `12` bars on either side prints a higher high or lower low. That means twelve bars of confirmation to the right, so the freshest leg is provisional until those bars close.

Why is MAPeriod seeded with a simple mean?

Because an exponential average calculated from a zero start draws a spike across the first bars of the chart. Seeding with a plain mean over `MAPeriod` `21` bars puts the recursion on a sensible footing, so the gold line begins at a real price level.

What is the TrendDot plot showing?

Which side of the gold line the close sits on, bar by bar. The aqua marker drops below price when the close leads the average and rises above it when the close lags. It gives you the state between crossings without reading the line itself.

Are results guaranteed?

No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Non repaint solar wind Indicator as one input. Always backtest before trading live.
