basic counter for a condition

[rtwave]

i could use some help putting together a counter for a condition i'm trying to code.


i want to have a condition called uptrend when these conditions are met (i don't know if a boolean variable would work):



if (Rising(smav) && Rising(emav) && Rising(hmav))


now, i would like the strategy to keep a count of how many consecutive bars this condition has been true for (or confirmed) and only act after a minimum count that i could define as an input has been met or exceeded.


let's say i define a variable as trendcount and the input is 3.


then, the counter for this uptrend condition would only follow through with the actions i code after 3 consecutive bars have met the conditions defined as uptrend in this case.


thanks.

Hello rtwave,

This can definitely be done through NinjaScript.

First, you will need a static variable to store your run length in, so that it can persist between OnBarUpdate calls. In the Variables section, below the line

[FONT=Courier New]// User defined variables (add any user defined variables below)[/FONT]

You will want to add this line,

[FONT=Courier New]private int runLength = 0;[/FONT]

Next, we can template out your increment code,

[FONT=Courier New]if (Rising(smav) && Rising(emav) && Rising(hmav))
{
  ++runLength;
  // your conditional code here
}[/FONT]

Next and immediately after the previous code, we can add your reset code,

[FONT=Courier New]else
{
  runLength = 0;
}[/FONT]

Finally, we can template out the code that acts after a minimum length consecutive run. We'll say that you defined the User Input "trendcount" already. Please let us know if you need help setting up User Input variables.

[FONT=Courier New]if (runLength >= trendcount)
{
  // your conditional code here
}[/FONT]

Not meaning to wax pedantic, but you mean a "class" variable, not a "static" variable. "static" has a very specific meaning in c#.
