hi
i want use zigzag and show up trend or down trend
i try this link
/algos/cbots/show/159
this cod :
using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
namespace cAlgo
{
[Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
public class testZigZag : Robot
{
[Parameter(DefaultValue = 0.0)]
public double Parameter { get; set; }
private Position _position;
private ZigZag _zigZag;
private double _prevValue;
[Parameter(DefaultValue = 12)]
public int ZzDepth { get; set; }
[Parameter(DefaultValue = 550)]
public int StopLoss { get; set; }
[Parameter(DefaultValue = 5)]
public int ZzDeviation { get; set; }
[Parameter(DefaultValue = 3)]
public int ZzBackStep { get; set; }
[Parameter(DefaultValue = 100000, MinValue = 0)]
public int Volume { get; set; }
protected override void OnStart()
{
// Put your initialization logic here
_zigZag = Indicators.GetIndicator<ZigZag>(ZzDepth, ZzDeviation, ZzBackStep);
}
protected override void OnTick()
{
// Put your core logic here
double lastValue = _zigZag.Result.LastValue;
if (lastValue < _prevValue)
Print("Up Trend");
else if (lastValue > _prevValue && _prevValue > 0.0)
Print("Down Trend");
_prevValue = lastValue;
}
protected override void OnStop()
{
// Put your deinitialization logic here
}
}
}
but expert not print any thing

First of all, value which you assign to the _prevValue field cannot be considered as a previous value of ZigZag. It is a last value calculated on the previous tick.
Second of all, ZigZag indicator doesn't write values to every index. Therefore in order to retrieve value which you selected on the image, you need to iterate through _zigZag.Result DataSeries and find a value which is not double.NaN.
thank you team Spotware
please you can set example .?

Please have a look at the following code snippet:
ZigZag zigzag;
protected override void OnStart()
{
zigzag = Indicators.GetIndicator<ZigZag>(12, 5, 3);
}
double GetZigZagValue(DataSeries dataSeries, int indexFromEnd)
{
for (var i = MarketSeries.Close.Count - 1; i >= 0; i--)
{
if (!double.IsNaN(zigzag.Result[i]))
{
if (indexFromEnd == 0)
return zigzag.Result[i];
indexFromEnd--;
}
}
return double.NaN;
}
protected override void OnTick()
{
var lastValue = GetZigZagValue(zigzag.Result, 0);
var previousValue = GetZigZagValue(zigzag.Result, 1);
if (lastValue > previousValue)
Print("lastValue {0} > previousValue {1}", lastValue, previousValue);
if (lastValue < previousValue)
Print("lastValue {0} < previousValue {1}", lastValue, previousValue);
}

Hi,
Does someone could to glue all these codes together correctly? (Base Zig Zag code, 1st post correction and next 4th post correction to 1st post)
I've tried to do it by myself but my C# is definitely too weak at this level.
Many thanks

Interestingly, had not read this topic.
I will try to do what you asked.

Thanks for try cjdduarte.
Of course I mean indy, not cBot ZigZag like is in this section.
Generally, I'm surprised that custom indicators section, in net, working at this platform is quite small. Especially that many people swap her with MT4.

I m very new on zig zag indicator. I have different programme which is based on c# but I could not working out your codes. (visit here, http://estore.directfn.com.tr/ReadMore.aspx?rmc=ideal). So what can I do?

Dear seyhaan,
Thanks for posting in our forum. It is not very clear what you are asking for. Do you want to use our indicators in your program? This is not possible, our Indicators require cAlgo or cTrader to run. If we misunderstood your question, please feel free to elaborate.
Best Regards,
cTrader Team

RE: Use values as Series
Hi Spotware Team:
Is it possible to obtain the values of the ZigZag as a Series? Below the values are stored in var.
Thanks!

Hi ericjavier.santiago,
In principle it is possible but the code needs to be modified accordingly.
