Many traders consider “round” levels, i.e. those in which the vertical coordinate (in points) ends with “00”, as support or resistance levels. Example – the levels of 1.5800 and 1.5900 for EURUSD. The RoundLevels indicator draws two closest “round” levels above and two below the current price.
This indicator was first implemented in MQL4 and published in Code Base at mql4.com on 29.03.2008.
