Frequently Asked Questions
Performance & Repainting
What is repainting, and does it affect execution?
Repainting happens when indicators adjust historical values after the candle closes. If your strategy fires alerts during candle formation, repainting may cause unexpected signals.
Repainting occurs when an indicator or strategy modifies historical values after new price data appears. This means that what you see on the chart after the candle closes may not be what existed during live real-time trading when the alert was supposed to trigger.
Repainting indicators update or redraw past candles to appear more accurate than they were live — giving a misleading impression of perfect entries.
How can I avoid repainting issues?
Use bar close alert only mode in TradingView.
Can ChartsConnect guarantee exact order fills?
No platform can guarantee fills because it depends on broker liquidity and network speed.
What can I do to reduce execution delay?
- Use a VPS close to broker servers
- Minimize parallel strategies
- Use JSON alerts, not plain text
- Monitor Execution Logs frequently
