What does it mean when a indicator forex repaints?


The forex market is one of the most dynamic and complex financial markets in the world. It is characterized by a high level of volatility, which makes it challenging for traders to make accurate predictions. In order to navigate this market successfully, traders rely on various technical indicators to help them identify potential trading opportunities. However, one issue that traders often encounter is the problem of indicator repainting. In this article, we will explain what indicator repainting is, why it occurs, and how it can affect your trading.

What is Indicator Repainting?

Indicator repainting occurs when a technical indicator changes its past values based on current price action. In other words, an indicator that repaints will change its values after the fact, making it difficult for traders to trust the signals it generates. This can be a problem because traders rely on technical indicators to help them make trading decisions. If an indicator repaints, the signals it generates may be inaccurate, leading to losses for the trader.


Why Do Indicators Repaint?

Indicators can repaint for various reasons. One of the most common reasons is the use of lagging indicators. Lagging indicators are technical indicators that use past price data to generate signals. These indicators are useful for identifying trends, but they can be slow to respond to changes in the market. As a result, they may repaint their values as new price data becomes available.

Another reason why indicators may repaint is due to the use of complex algorithms. Some indicators use complex mathematical formulas to generate signals. These formulas may be designed to adjust the indicator’s values based on certain market conditions. However, if the algorithm is not properly designed, it may cause the indicator to repaint its values.

How Does Indicator Repainting Affect Trading?

Indicator repainting can have a significant impact on trading. If a trader relies on an indicator that repaints, they may receive false signals that lead to losses. For example, if an indicator generates a buy signal, but then repaints its values to show a sell signal, the trader may end up selling at a loss. In this case, the trader may have been better off not using the indicator at all.

In addition, indicator repainting can also lead to confusion and frustration for traders. If an indicator constantly changes its values, it can be difficult to know when to enter or exit a trade. This can lead to indecision and missed opportunities.

How Can Traders Avoid Indicator Repainting?

There are several ways that traders can avoid indicator repainting. One way is to use leading indicators instead of lagging indicators. Leading indicators use current price data to generate signals, making them more responsive to changes in the market. This can help traders avoid false signals generated by lagging indicators.

Another way to avoid indicator repainting is to use simpler indicators. Simple indicators are less likely to repaint their values because they use basic mathematical formulas to generate signals. This can make them more reliable for traders.

Finally, traders can also avoid indicator repainting by testing their indicators before using them in live trading. Traders can use backtesting software to test their indicators against historical price data. This can help them identify any issues with indicator repainting before they start trading with real money.


Indicator repainting can be a significant problem for traders in the forex market. It can lead to false signals, confusion, and missed opportunities. However, traders can avoid indicator repainting by using leading indicators, simpler indicators, and by testing their indicators before using them in live trading. By taking these steps, traders can increase their chances of success in the forex market.
