The Non Repaint Arrow Indicator for MT4 is a strong and popular custom tool for the MetaTrader 4 trading platform. It is primarily developed to provide traders clear and actionable buy or sell signals on a chart using arrow symbols. The phrase “non-repaint” relates to an important feature of this indicator: once a signal is created and shown on the chart, it does not alter, vanish, or move after the candle closes. This is in contrast to many repainting indicators, which alter previous signals when fresh price data becomes available, creating the appearance of increased accuracy in retrospect.

What is the Non Repaint Arrow Indicator for MT4
An arrow indicator in MT4 is a visual tool that displays arrows directly on the chart, often upward arrows (for buy signals) and downward arrows (for sell signals). These arrows are based on certain technical circumstances determined by price action, trend direction, or a combination of indicators. The idea is to give a simple, visually appealing indication for trade entry or exits.
However, many of these arrow indicators are repainting, which means they may redraw or erase signals in response to fresh candle data. This makes them untrustworthy, particularly for live trading, since traders may act on a signal that then disappears. This is where non-repaint arrow indicators become noticeable.
What Does “Non-repaint” Mean?
In trading, “repainting” refers to an indicator updating its previous indications when fresh price data becomes available. For example, an indicator may show a purchase arrow on the current candle, but if the price changes negatively, the arrow may vanish or transfer to another candle.
In contrast, a non-repaint indicator locks in the signal as the candle closes. It does not change past signals, regardless of future price movements. This attribute makes it a popular option among traders who prioritize precision and consistency, particularly in backtesting and live trading.
How the Non-Repaint Arrow Indicator Works
The non-repaint arrow indication is often developed on top of one or more technical analysis tools, such as:
- Use Moving Averages (MA), Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), Stochastic Oscillators, Support and Resistance Levels, and Fractals/Price Action Patterns. Depending on the logic utilized, when a specified set of requirements is satisfied (for example, a moving average crossing, RSI entering oversold territory, or a candlestick pattern emerging), the indicator draws an arrow on the chart – normally on the beginning of the next candle after confirmation. For example, a Buy Arrow may show when the RSI is below 30 (meaning oversold) and the price crosses above a 50-period moving average.
- A Sell Arrow may appear when the MACD crosses downward and the price is rejected at a resistance level. The key is that once the candle closes and the arrow appears, it remains there, allowing traders to trust the signal’s past accuracy.
Advantages of a Non-Repaint Arrow Indicator
- Reliable Backtesting: Because signals do not repaint, traders may securely test strategies against past data without fear of misleading outcomes.
- Clarity in Decision Making: The visual arrows make trade signals simple to understand, especially for new traders.
- Consistency: Non-repaint indicators provide consistent indications across demo and live accounts.
- Reduced False Confidence: Many traders believe repainting indicators are reliable since previous signals seem to be flawless. Non-repainting eliminates this psychological issue.
Drawbacks and Limitations
- Lagging Nature: Because the indicator waits for confirmation (typically the closing of the candle), there may be a delay between the actual market change and the indication.
- No Guarantee of Accuracy: As with other indicators, the non-repaint arrow indication is not infallible. False signals persist, particularly in turbulent or range markets.
- Over-Reliance Risk: Some traders depend only on indicator arrows, ignoring other technical or fundamental variables, which may result in poor decision-making.
Best Practices for Using Non-Repaintable Arrow Indicators
- Use as Confirmation, Not as a Single Entry: Combine the arrow signals with other types of analysis, such as support/resistance, trendlines, or fundamental news.
- Set Stop Losses: When trading, always use good risk management since misleading signals are possible.
- Avoid Low Liquidity Times: Many indicators, including this one, underperform during thin markets, such as post-news volatility or market closing.
- Test Before Live Use: Use a demo account to see how the indicator performs in real-time market situations.

Developers often tweak these indicators to accommodate scalping, intraday, or swing trading techniques. Some EAs (Expert Advisors) are also created using the non-repaint arrow indication as their primary signal generator.

Conclusion:
