Non Repainting Buy Sell Indicator (HA, EMA, RSI Filter Stack)

Written by Dominic Walsh · Published 22 Jun 2026 · Last updated 20 Aug 2026

The non repainting buy sell indicator plots BUY and SELL arrows on a closed EURUSD H1 bar. It only fires once four checks agree. Those are Heiken Ashi color, an EMA trend filter, an RSI cross, and a tick volume push. Traders who want fewer, filtered arrows instead of constant noise get the most from this stack.

This build ships as non-repainting-buy-sell-indicator-forexmt4systems.ex4 for MT4 and non-repainting-buy-sell-indicator-forexmt4systems.ex5 for MT5; the screenshots below come from EURUSD H1.

What the Non repainting buy sell Indicator draws on the chart

BUY (lime, code 233) sits below the bar’s low. It only appears once every filter agrees on a bullish read.

SELL (red, code 234) sits above the bar’s high. It only appears once every filter agrees on a bearish read.

• BUY: arrow, lime, width 2, arrow code 233
• SELL: arrow, red, width 2, arrow code 234

How the Non repainting buy sell Indicator calculates its values

Heiken Ashi color confirmation

The code rebuilds Heiken Ashi values first. It uses the real open, high, low and close of every bar. The smoothed close buffer averages the four raw prices.

The smoothed open buffer averages the prior Heiken Ashi open and close. Each smoothed candle carries a memory of the one before it. A bullish setup needs HaConfirmBars closed candles where the smoothed close sits above the smoothed open. A bearish setup needs the same count on the other side. HaConfirmBars defaults to 1.

EMA trend filter and the RSI cross

EmaPeriod feeds an EMA call, averaging the last 50 closes by default. Price must close above that average for a buy, and below it for a sell. The arrow only fires with the trend.

RsiPeriod drives an RSI reading on the current bar and the one before it. A buy needs RSI to cross up through RsiBuyLevel. A sell needs it to cross down through RsiSellLevel. Both levels default to 50.0.

Volume push and the cooldown

When UseVolumeFilter stays on, the code averages tick volume over the last VolMaPeriod bars. It then checks that the current bar clears VolMult times that average. VolMaPeriod defaults to 20 and VolMult defaults to 1.0.

CooldownBars then blocks a fresh arrow until that many bars pass since the last one. A single strong swing cannot fire five arrows in a row. Four bars is the default gap.

How to read the signals

A lime BUY arrow needs four things on one closed bar. Heiken Ashi turns bullish, price closes above the EMA, RSI crosses up through 50, and volume clears its filter.

A red SELL arrow flips every one of those checks. Bearish Heiken Ashi, price under the EMA, RSI crossing down through 50, and a volume confirmation, all together.

The scan skips the still-forming bar. An arrow only appears once its bar has closed, so it will not move or vanish later.

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

Alerts cover popup, push, email and sound together. EnableAlerts fires once per closed bar using the time[1] guard, so a flood of mid-bar alerts cannot happen.

Every Non repainting buy sell Indicator input

Core settings

Setting	What it does	Default
EmaPeriod	EMA trend filter period. EmaPeriod sets the EMA trend filter length. It defaults to 50. A shorter value reacts faster but tags more counter-trend noise.	50
RsiPeriod	RSI period. RsiPeriod sets the RSI lookback behind the midline cross. It defaults to 14, matching Wilder’s classic setting.	14
RsiBuyLevel	RSI cross-up level for buys. RsiBuyLevel is the level RSI must cross up through for a buy. It defaults to 50.0.	50.0
RsiSellLevel	RSI cross-down level for sells. RsiSellLevel mirrors RsiBuyLevel on the sell side. It also defaults to 50.0.	50.0
HaConfirmBars	Heiken Ashi bars to confirm. HaConfirmBars sets how many closed Heiken Ashi candles must agree on color before a signal counts. It defaults to 1.	1
CooldownBars	Bars between consecutive signals. CooldownBars spaces signals apart. Its default of 4 bars stops the indicator from stacking arrows during one strong swing.	4
UseVolumeFilter	Require above-avg tick volume. UseVolumeFilter turns the tick volume check on or off. It defaults to true.	on
VolMaPeriod	Volume MA period. VolMaPeriod sets the tick volume average window. It defaults to 20 bars.	20
VolMult	Min volume multiple of MA. VolMult is the minimum multiple of that average a bar must clear. It defaults to 1.0.	1.0

Display settings

Setting	What it does	Default
ArrowOffsetPts	Arrow vertical offset (points). ArrowOffsetPts is a cosmetic point offset, defaulting to 18, that keeps arrows clear of the candle wicks.	18

Alert settings

Setting	What it does	Default
EnableAlerts	Master alert switch.	on
EnablePopup	Popup alert.	on
EnablePushNotify	Mobile push.	on
EnableEmail	Email.	off
EnableSound	Sound.	on

Settings that fit your chart

The screenshot runs on EURUSD H1. The default filter lengths line up well with that pace. Four checks must agree at once, so lower timeframes tend to produce fewer signals than a single moving-average cross would. That suits traders who trade less often but want a cleaner read. The same logic also runs on other forex majors and higher timeframes without any rebuild.

When the Non repainting buy sell Indicator fails

In a ranging market the EMA trend filter and the RSI midline cross often disagree. The indicator can sit quiet for long stretches even while price swings inside a range.

Tick volume counts price changes, not real traded volume. The VolMult filter can pass or block a bar for reasons that have nothing to do with actual participation.

Four conditions must line up on one closed bar. A genuine reversal that satisfies only three of them prints no arrow at all, so some real turns get skipped.

FAQ

Why does the BUY arrow need both an EMA filter and an RSI cross?

The BUY arrow only plots when price closes above the EmaPeriod average, with RSI crossing up through RsiBuyLevel on the same closed bar. Pairing the two filters cuts down on RSI crosses that fire against the wider trend. It also filters out EMA closes with no real momentum behind them. Heiken Ashi color and the volume check still have to agree too.

What does HaConfirmBars actually control?

HaConfirmBars sets how many closed Heiken Ashi candles in a row must share the same color. The default is 1, so a single smoothed candle already counts. Raising it to 2 or 3 demands a longer streak. That cuts noise but delays every signal by that many extra bars.

Does UseVolumeFilter read real traded volume?

No. UseVolumeFilter compares tick volume, the count of price changes MetaTrader records per bar, against a VolMaPeriod rolling average times VolMult. It works as a proxy for activity, not a broker feed of real traded size. A quiet session with wide spreads can still clear the filter.

How does CooldownBars change signal spacing?

CooldownBars stops the indicator from stacking BUY or SELL arrows too close together. The default is 4 bars. Once an arrow prints, the code will not print another until at least 4 bars pass, even if every filter lines up again sooner.

Are results guaranteed?

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