SMA Projection

前天

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.
