คำอธิบาย

Overview
This indicator is a Supertrend-style trend follower that confirms direction changes only after a bar closes. Trend flips are determined using the previous bar’s close relative to the bands, which helps avoid intrabar changes during live candles.

How it works

Computes ATR (Average True Range)
Builds upper/lower bands using ATR and a multiplier
Updates trend direction only when a prior candle confirms a break of the band


Confirmation logic (bar-close based)
Trend direction is updated using conditions based on the previous candle, such as:

close > upper → confirm uptrend
close < lower → confirm downtrend

Because signals are confirmed on the prior bar, trend changes and markers are displayed only when confirmation exists.

Signals

Uptrend confirmation: prior candle closes above the upper band → bullish marker
Downtrend confirmation: prior candle closes below the lower band → bearish marker


Inputs

ATR Length (default 10)
ATR Multiplier (default 3.0)


Notes
This script is intended for bar-close workflows. Behavior and responsiveness may differ across markets and timeframes depending on volatility and chosen settings.
