The repaints here are not so much an issue in my type of trading - I use it as a bias filter, not a trigger.
On longer horizons like i normally set up trades (I may close them out earlier) noise gets smoothed anyway and the exact day of signal matters less. Structural trend matters more and you usually hold through volatility, even if signal shifts 1–3 bars my 30- 60-day move isn’t destroyed. Use them for macro state and combine with non-repainting confirmations. Never backtest them mechanically and accept they are descriptive, not predictive.
