how to use indicator in a strategy

[qewcool]

hi

I have written a custom indicator and want to use its readings in a custom strategy.

How do I read the indicator from my strategy ?

Can anyone help with a sample code ?

Thanks in advance

qewcool, you would just call it like the standard indicators, for example -

 
double myIndicValue = MyIndicator(Parameter1, Parameter2)[0];

Just type your indicator name and add the brace, then Intellisense should offer you the overload you would need...

Thanks for the reply

Sorry im a bit newbish to coding with NT

So if i understand this will take the value of what is plotted in the value dataseries of the custom indicator ?

What if my indicator had several plots (which it in fact has) ? how do I select which plot it will read when I call it.

Or it will just read the first plot and the other plots cannot be read from a strategy ?

Thanks for helping

qewcool,

What Bertrand posted is good for accessing the values of a single plot indicator or DataSeries. If your indicator has several plots you can access the plots by their names individually.

Take a look at the MACD indicator for instance. It has 3 plots. You can access them like so:

MACD(some parameters).MACD[0]; <-- gets you the values of the MACD plot
MACD(some parameters).Avg[0]; <-- gets you the values of the Avg plot

I don't know how to correct this code error I looked up error CS0119 but couldn't figure out a solution. I tried the same code with MACD histogram and it worked but with this RSqueeze indicator it keeps giving an error.


if (RSqueeze(RSqueeze.Utility.SqueezeStyle.CounterTre nd).PMomentumDown[0] > RSqueeze(RSqueeze.Utility.SqueezeStyle.CounterTren d).NMomentumUp[1])
{
DrawArrowUp("My up arrow" + CurrentBar, false, 0, 2, Color.Yellow);

Thanks

chipotlebop,

Can you please provide the exact text of that error message? I am not sure what CS0119 refers to. Thank you.

Hi Josh


Strategy\AlertSqueeze.cs 'NinjaTrader.Strategy.Strategy.RSqueeze(RSqueeze.U tility.SqueezeStyle)' is a 'method', which is not valid in the given context CS0119 - click for info 45 26

Thanks

Likely complaining about your use of RSqueeze.Utility.SqueezeStyle. It is saying RSqueeze is a method and you can't just use it as if it was a property.

Please check with the original author of this script to see how to properly parameterize it.
