200-Day SMA & EMA with StdDev Bands and Cross Tracking

Locks everything to the daily chart, regardless of which timeframe you’re viewing.

Plots two main moving averages:

A 200‑period Simple Moving Average (SMA).

A 200‑period Exponential Moving Average (EMA).

Draws shaded “bands” around each average at ±0.5σ, ±1σ, ±1.5σ, ±2σ, ±2.5σ, and ±3σ, with progressively fainter lines as you move farther from the mean.

Highlights a “stable zone” in the background when price has stayed within one standard deviation of the SMA for more than a user‑defined number of bars.

Detects and marks “deviation crossovers” between the SMA and EMA bands at 2σ, 2.5σ, and 3σ levels:

Draws a small circle at the crossover point.

Extends a line forward 500 bars at that price.

Automatically removes that line if price later touches it.

Marks Golden and Death Crosses (when the 50‑day EMA crosses the 200‑day EMA):

“GC” for Golden Cross, plotted in green.

“DC” for Death Cross, plotted in red, with the same forward‑extending line logic.
