How to make a buy and sell signal?

[fragalles]

Hello

i have the most fundamental question:

How can i create a buy or sell signal from an event (several indicator parameters occured, not a single value reached a certain level)?

I am using the zigzag indicator and in the indicator there is a line that i want to use as a sell trigger:

if ((addHigh || updateHigh)

at the moment i am outputting an alert

Alert("sell now")

but i would like to make this event accessible by a strategy in the wizard.

I know that i would have to create a new plot inside the indicator and that the plot has to be something like -1 for sell and +1 for buy signal. But is not working.

Can you sent me the actual lines of code that are required to make an event inside an indicator available in the strategy wizard?

thank you very very very much

I suggest create a dummy indicator via the Wizard with a plot name "TriggerEvent", then generate it. Look at the code generated in the Initialize() for this plot, copy to to your other indicator, then look in the Properties section and copy the TriggerEvent property to your other indicator.

The TriggerEvent property will point to "Values[0]", you will need to change this in the indicator you copied to. Take a look at how many plots you had inititially. If only 1, then you this new one is the 2nd plot so change "Values[0]" to "Values[1]" for example.

How to test if everything went right?

I added this strategy to test if the indicator outputs the correct buy and sell signals:

if (_myfibtarget(DeviationType.Percent, 0.34, false, true).Plot0[0] == 1)
{
DrawDot("My dot" + CurrentBar, false, 0, Low[0], Color.Blue);
}

but I dont see any dots been drawn. So i guess the indicator is still wrong...

In the indicator itself i am using Value [1]:
public DataSeries Plot0
{
get { return Values[1]; }
}

because it is the 2nd plot
Add(new Plot(Color.Blue, PlotStyle.Line, "_zigzag"));
Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));

on the bar update when my buy entry condition is there i am setting:

Plot0.Set(1);

Can you have a look at the attached indicator to see whats still missing (its the basic zigzag indicator with the additions you wanted me to add)


Many thanks for helping me

Likley Plot0 is never set to a value of 1.

[fragalles]

how can i set the plot0 to true or false or 1 and 2

how can i set the plot0 to true or false or 1 and 2 so i can access it from a strategy?

i want when this event is activated in the zigzag indicator to set my buy signal:
if ((addHigh || updateHigh))
{

Plot0.Set(1);

Likley Plot0 is never set to a value of 1.

You must set it to a value. What I do is set to zero when false, 1 when true.

if (condition is true)
    Plot0.Set(1);
else
    Plot0.Set(0);

Your logic looks fine I am just saying that the setting value to 1 likely is never called.

zigzag indicator maybe not compatible with this kind of plots setting?

when i do so only the first time the event happens my dot is drawn at the point where the signal occured.

is it maybe in the nature of the zigzag indicator that it resets the on bar events all the time?

Unfortunately I don't know. From a logic perspective, what I have provided will work at a core level.

[fragalles]

is there maybe a simpler way to check if the zigzag indicator has currently the
addHigh or updateHigh set to true?

instead of adding a new Plot which would require for every indicator to have a special version with a plot function inside, for me the tradestation way to call
actual conditions of an indicator seams to me the more clever alternative...

at the moment i know that i can only check of values of dataseries of an indicator.

what would be the syntax to check for the above mentioned condition?

The only values accessible by our ZigZag indicator are bars again a high/low is made and the value of the high/low.

missing example

on the zigzag help page i am missing an example to check if the last bar was a new zigzag point.

i tried checking for a new high with this command, but again no dots are drawn on the chart:

if (ZigZag(DeviationType.Percent, 0.34,true).HighBar(1, 1, 1) == 1)
{
DrawDot("My dot" + CurrentBar, false, 0, Low[0], Color.Blue);
}

Am i right that the statement in the bracket would output a 1 when on the last bar a new high was found?

High Bar
ZigZag(DeviationType deviationType, double deviationValue,dbool useHighLow).HighBar(int barsAgo, int instance, int lookBackPeriod)

The only values accessible by our ZigZag indicator are bars again a high/low is made and the value of the high/low.

I believe it should be:

(ZigZag(DeviationType.Percent, 0.34,true).HighBar(0, 0, 1) == 1)

however, I suggest just printing some values out, changing parameters to see what the output is so you gain an understanding of how it works.

thank you my strategy finally is working

thank you

ZigZag(DeviationType.Percent, 0.34,true).HighBar(0, 1, 1) == 2

triggers the event that a new potential zigzag high is set, when combining this with other indicators its is a very good entry point for a short trade!

I believe it should be:

(ZigZag(DeviationType.Percent, 0.34,true).HighBar(0, 0, 1) == 1)
