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


Vars: Trend(0), DnTrend(False), UpTrend(False), DnTrendLow(999999),UpTren dHigh(-99999),
UpTrendLow(0),DnTrendHigh (0), UpTrendDate(0), DnTrendDate(0), DownTrendBar(0), UpTrendBar(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;

End;

If Trend = 1 and UpTrendHigh < High then

How is this different from a zigzag indicator?

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.

ZigZag indicator is different

Why don’t you just replace the conditions for ZigZag turns with conditions for your turn in the zigzag code?

Because it is less effort if someone else do it.

I tried to modidy ZigZag Indicator code but the result isn't what i wanted

I only want to 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.

You are probably looking for a ZZ that is not dynamic in nature so that you can do some automated strategy. The code you are looking for has been done by Spyros Raftopoulos in 2003. He originally coded it in Metastock and although there is a TS version, the published code requires more modification to match that of the Raftopoulos.

http://www.traders.com/Documentation...adersTips.html

Spyros Raftopoulos's article in this issue, "The Zigzag Trend Indicator," describes a method of deducing trend from reversal filters. In earlier articles, Raftopoulos described methods for charting zigzags, but his zigzag validity indicator only displayed the "locked" high and low, not the moment when the retracement criteria were met. Raftopoulos's new zigzag trend indicator, described in this issue, can now display this previously undisplayed information on the chart.
