已更新 SMA Projection
What it does
Draws a linear projection of a Simple Moving Average (SMA) 20 bars into the future using the SMA’s recent slope. Optionally shows a tiny momentum flag (just a number) positioned 0.75× ATR below the SMA on the last bar. No future data is read; everything updates on the current bar only.
How it works
SMA: Standard SMA on your chosen source and length.
Projection (fixed 20 bars): Uses a linear extrapolation from the last SMA value with slope
slope = (ma - ma[slopeLen]) / slopeLen
Momentum magnitude (optional): A signed number where >0 = up-slope, <0 = down-slope, ~0 = flat. Units are selectable: price/bar, %/bar, or ATR/bar (default). The flag is rendered small and colored teal (pos) / red (neg) / gray (flat).
Key features
Fixed 20-bar projection (no input—keeps it simple and comparable).
Tiny numeric momentum flag (off by default) placed well below the line (0.75× ATR).
Unit choices for momentum: price/bar, %/bar, ATR/bar.
Deadband option to zero-out tiny slopes.
Non-repainting projection: drawn only on the last bar; updates each candle.
Inputs (summary)
SMA length and Source
Slope lookback (for magnitude)
Show momentum flag (default: Off)
Magnitude units: price/bar, %/bar, ATR/bar (default)
Deadband and Decimals for display control
Tips
For smoother projections, increase slope lookback; for responsiveness, decrease it.
Use ATR/bar or %/bar if you want momentum values that are more comparable across symbols and timeframes.
The projection is indicative, not predictive—combine with structure, volume, and risk management.
Notes & limits
The “future” line is just a linear extrapolation from recent behavior; regime shifts will break linearity.
The momentum flag text is intentionally minimal to avoid chart clutter.
Works on any timeframe; the projection distance is always 20 bars on that timeframe.
