HiLo Marker is a cTrader indicator that automatically identifies and marks key price Highs and Lows on trading charts. It scans a configurable historical range ("Distance Window") to detect the absolute highest and lowest bars within that period, then places customizable markers above or below these bars to highlight significant swing points. This visual aid helps traders quickly recognize market structure, including swings, trends, and ranges, and identify potential support and resistance zones. The indicator supports all financial instruments such as Forex, Gold, Indices, Crypto, and Stocks, and works on any timeframe. Users can adjust marker colors and the offset distance from the price to suit their chart preferences. The "Distance Window" parameter allows tailoring the sensitivity of swing detection, with smaller values capturing minor swings suitable for scalping, and larger values highlighting major trend reversals ideal for swing trading or higher timeframes. HiLo Marker streamlines price action analysis by providing objective, automated identification of critical market turning points.
