Calling terms from another indicator

[Insearch]

I'm trying to set up a sound alert based on certain indicators reaching a predefined level. Those indicators were also programmed in Ninjascript. How can I call on some of those levels in a new indicator (the indicator for sound alert)

Some examples:

if (MACD(12, 26, 9).Avg[0] > someValue)
if (MACD(12, 26, 9).Diff[0] > someValue)
if (RSI(20, 3)[0] > someValue)
if (RSI(20, 3).Avg[0] > someValue)

Thx, but the indicator is not a standard one, it was programmed by someone . . . will the script recognize it anyway or do I have to in some way reference the indicator name?

[NinjaTrader_JoshP]

You will have to reference the indicator name and then the plot name. Unfortunately I cannot assist you much since I do not know how your indicator was programmed. You may want to ask the author directly.

Unfortunately, I don't know who the author is . . . it was a post on a forum. But maybe you can help. I can't post the whole code here (it's pretty long) but see below for the relevant sections.

I want an sound alert when both conditions are met in either of the following 2 situations:

Situation 1
trendingHist < -10
primeLow [1] > primeLow [0]

Situation 2
trendingHist > 10
primeHigh [1] < primeLow [0]

The indicator is named gpLogicPrimes

This is in the variables section:
privatedouble[] primeHigh; //Array for prime highs
privatedouble[] primeLow; //Aray for prime lows

DataSeries trendingHist; //Trending Histogram

This is in the onbarupdate section:

//Calculate Trending Histogram
trendingHist.Set((trendingERG[0] - trendingERG[1]) * 75);

. . . .

//Display price at each extreme support peak, update list with new extreme price value
if (eRGTradingSupport)
{
if (LowestBar(Low, CurrentBar - supportOscTradeBar) == 0 )
{

primeLow[1] = Low[0];

if (primeLow[1] > primeLow[0])
{ . . . .

Insearch,

Unfortunately I cannot be of much assistance. For 3rd party indicator support you will have to inquiry the original author.

As a guess you can try something along the lines of this in a separate indicator:

if (gpLogicPrimes().trendingHist[0] < -10 && gpLogicPrimes().primeHigh[1] > gpLogicPrimes().primeLow[0])
     // Do something;

Thx, I'll try that . . . what I really needed was the syntax . . .

Will I have to input anything in the variables section or initialize section of the "new" code?

[NinjaTrader_JoshP]

Like I mentioned earlier Insearch, there is not much I can do to assist you, especially for syntax. I have no idea how the 3rd party indicator was created and as such you have to talk to the original author. There is nothing more I can do.

You generally do not need to do things in Initialize or Variables.
