Overview
The script calculates the EMA using a configurable length and timeframe, then applies request.security to retrieve the value without repainting. It draws the line over the chart, colored green when price is above the EMA or red when below, with an option to smooth the plot. Main settings allow changing the EMA timeframe to daily or other intervals, adjusting the length, toggling color, and enabling smoothing. This tool helps traders identify trend direction in intraday markets using higher timeframe data.
