Detrended Price Oscillator in Crypto: Why the Value Changes Before Candle Close

The Detrended Price Oscillator compares price with a moving average from the past. Many versions also shift the plot, so the live value appears at an earlier bar.

Short answer

DPO = close − SMA(N) taken from N/2 + 1 bars earlier (one common definition). Some implementations plot it displaced back in time to centre the average, which means the most recent plotted values are filled in later — a form of repainting. On the live bar, the close term moves with price. Check which version your tool uses: undisplaced DPO is usable for signals on closed bars; displaced DPO is for cycle analysis, not real-time triggers.

A displaced DPO looks very smooth in history because each point was drawn with knowledge of later bars.
