    Hello
    here is a screenshot about what i want to do : plot points at the extremes of high / low

    An Upswing starts when a bar s high and low prices rise above the respective high and low prices of the latest Downswing. Prices then remain in an Upswing until such a bar that the high and low prices decline below the respective high and low prices of the highest bar of the Upswing. The highest price in the Upswing is called a TOP

    A Downswing starts when a bar s high and low prices decline below the respective high and low prices of the highest bar of the latest Upswing. Prices then remain in a Downswing until a bar high and low prices rise above the respective high and low prices of the lowest bar of the Downswing. The lowest price in the Downswing is called a BOTTOM.

    in my code, points aren't plotted at the extremes of high / low

    THANKS YOU FOR HELP

    Code:
    Vars: Trend(0), DnTrend(False), UpTrend(False), DnTrendLow(999999),UpTrendHigh(-99999), 
    UpTrendLow(0),DnTrendHigh(0), UpTrendDate(0), DnTrendDate(0), DownTrendBar(0), UpTrendBar(0); 
    Arrays: LastH[3](0), LastLo[3](0),DateH[3](0),DateLo[3](0); 
    
    { Downtrend = one down bar / Uptrend = one up bar } 
    DnTrend = High < High[1] and Low < Low[1]; 
    UpTrend = High > High[1] and Low > Low[1]; 
    
    { We define a change from an Uptrend to a Downtrend as a simple Downtrend combined with 
    the low lower than the low recorded on the day of the highest bar of the latest Uptrend. } 
    If DnTrend = True and Low <= UpTrendLow then Trend = -1; 
    
    { We define a change from a Downtrend to an Uptrend as a simple Uptrend combined with 
    the high greater than the high recorded on the day of the lowest bar of the latest Downtrend. } 
    If UpTrend = True and High >= DnTrendHigh then Trend = 1; 
    
    { Keep track of the high recorded on the day of the lowest low of a Downtrend 
    Keep track of the low recorded on the day of the hightest high of an Uptrend } 
    If Trend = 1 and High > UpTrendHigh and High > High[1] then UpTrendLow = Low; 
    If Trend = -1 and Low < DnTrendLow and Low < Low[1] then DnTrendHigh = High; 
    
    If Trend = -1 and DnTrendLow > Low then 
    Begin 
    DnTrendDate = Date; 
    DownTrendBar = CurrentBar; 
    DnTrendLow = Low; 
    End; 
    
    If Trend = 1 and UpTrendHigh < High then 
    Begin 
    UpTrendDate = Date; 
    UpTrendBar = CurrentBar; 
    UpTrendHigh = High; 
    End; 
    
    If Trend = 1 and Trend[1] <> 1 then 
    Begin 
    LastLo[0] = DnTrendLow; 
    DnTrendLow = Low; 
    DateLo[0] = DnTrendDate; 
    Plot1(LastLo[0],"Dn"); 
    //Plot1[CurrentBar - UpTrendBar](LastLo[0],"Dn"); 
    End 
    Else 
    NoPlot(1); 
    
    If Trend = - 1 and Trend[1] <> -1 then 
    Begin 
    LastH[0] = UpTrendHigh; 
    UpTrendHigh = High; 
    DateH[0] = UpTrendDate; 
    Plot2(LastH[0],"Up"); 
    //Plot2[CurrentBar - DnTrendBar](LastH[0],"Up"); 
    End 
    Else 
    Noplot(2);
