If you have ever bought an indicator whose chart history looked flawless but whose live signals felt very different, repainting is a likely reason.
What is repainting?
An indicator repaints when it changes its past output as new prices arrive. A BUY arrow might appear on a candle, then move to a later candle, or vanish entirely once the market turns. Looking back at the chart, you only see the signals that survived, so the history looks far better than what anyone could have traded in real time.
Why indicators repaint
- Calculating on the current, unfinished candle and redrawing as it changes.
- Using future data, such as swing points that can only be confirmed several candles later, and placing the signal back on the earlier candle.
- Recalculating the whole history each time the chart updates.
What non-repainting means
A non-repainting indicator prints a signal only once its conditions are confirmed and then leaves it alone. What you see in the history is what the indicator showed at the time. This makes it possible to review past signals honestly.
How to check an indicator yourself
- Run it on a live or demo chart for a few sessions and take screenshots as signals appear.
- Compare those screenshots with the same chart later on.
- Use the Strategy Tester in visual mode and watch whether signals move as candles form.
What it does not mean
Non-repainting is about honest display, not about accuracy. A confirmed signal can still be followed by a losing trade. Dream Ultra is non-repainting, and like every trading tool it carries risk.
