Overview

Polish calculates 21, 50, optional 100, and 200-period smoothed moving averages alongside a short-term moving average trend fill. Pattern detection identifies three-line strike and engulfing setups filtered against the 200 SMMA trend baseline. Users can toggle specific candlestick signals, adjust session time parameters across chosen days of the week, and configure moving average visibility.

Smoothed moving averages for multiple periods
Three-line strike candlestick pattern alerts
Trend-filtered engulfing candle identification
Customizable trading session background coloring
