Imagine an indicator showing a buy signal on your chart, only for that signal to vanish or relocate after the market moves against you. This phenomenon is known as repainting, and it's more prevalent than many traders realize. In this post, you'll learn what causes repainting, how to identify it, and strategies to avoid its pitfalls.
Understanding the technical reasons behind repainting can help you avoid costly mistakes. Repainting primarily occurs when indicators use unavailable data at the time of a signal. Common causes include:
