Uno Market Sessions is a cTrader indicator designed to visually display the four major global trading sessions: Sydney, Tokyo, London, and New York. It overlays dynamic shaded boxes on price charts to highlight the exact high-low range of each session, helping traders identify key market activity periods in real time. Users can toggle individual sessions on or off and customize the appearance with adjustable opacity, 11 color presets, and eight font options for labels. The indicator also supports historical analysis by allowing users to set how many days of session data to display, aiding in the study of price reactions to previous session highs and lows. The clean user interface features refined dotted borders to maintain chart clarity. By clearly marking session ranges and overlaps, such as the London/New York overlap and Asian session breakouts, the indicator assists traders in spotting breakouts, timing entries around liquidity surges, and identifying institutional support and resistance levels. It is applicable across multiple markets including Forex, indices, commodities, stocks, and cryptocurrencies. The product includes a video tutorial and supports professional customization to fit various chart themes and trading styles.
