Schaff Trend Cycle

[myalgomate]

The Schaff Trend Cycle (STC) is a charting indicator that is commonly used to identify market trends and provide buy and sell signals to traders. Developed in 1999 by noted currency trader Doug Schaff, STC is a type of oscillator and is based on the assumption that, regardless of time frame, currency trends accelerate and decelerate in cyclical patterns.

Thanks for the recommendation and info. Tracking dev here: #571

[DaveSkender]

This was implemented in version 1.18.0

On reading about this a bit more, STC is just a Slow Stochastic of a MACD. Given that these two are already in the library, you can compute things like this on your own; for example, STC is:

IEnumerable<StochResult> stochMacd = quotes
  .GetMacd(fastPeriods, slowPeriods, 1)
  .Where(x => x.Macd != null)
  .Select(x => new Quote    // create synthetic Quote of MACD
  {
      Date = x.Date,
      High = (decimal)x.Macd,
      Low = (decimal)x.Macd,
      Close = (decimal)x.Macd
  })
  .GetStoch(cyclePeriods, 1, 3);

[DaveSkender]

With that said, when you do it this way the results will not be the same length as the original quotes due to the interim pruning needed for the Stoch calculation. As such, I'm still building this as a standalone indicator.

[DaveSkender]

I provide this example just to demonstrate how you can generally create your own composite indicator of indicators.

Прошу подсказать как мне встроить в ваш код такую конструкцию?
Can you please tell me how to build this construct into your code?

function SchaffTC(period, s_len, l_len)
{
	/// Schaff Trend Cycle
	/// @link https://forum.amibroker.com/t/schaff-trend-indicator-stc/13355/6
	local MCD, frac1, Frac2, PF, PFF;
	MCD = MACD(s_len, l_len);

	//StochK of MACD
	C = H = L = MCD;
	frac1 = StochK(period, 1);

	//Smoothed calculation
	PF = AMA(frac1, factor = 0.5);

	//StochK of PF
	C = H = L = PF;
	Frac2 = StochK(period, 1);
	RestorePriceArrays();

	//Smoothed calculation
	PFF = AMA(Frac2, factor);
	return PFF;
}

[DaveSkender]

Do you know what "AMA" is here?
I'm also wondering if this is different or the same as our existing Schaff Trend Cycle indicator.

[DaveSkender]

Ok, thanks for the info. I think I’ll use this as an example of how to add a custom private indicator that works identically to the ones in the library. See #698

[turok2000]

То есть мне ждать разработки?

[ooples]

This code is just a Schaff Trend Cycle with custom Kaufman Adaptive Moving Average as a smoother for the final result

[DaveSkender]

It's a bit odd to have factor = 0.5 as an input value for AMA, rather than being calculated "adaptively". Smells funny.

[turok2000]

Буду благодарен если вы покажете пример адаптивного использования factor )))

[turok2000]

Прошу помогите, запрограммировать данный код что я представил. Можно на мою почту ([email removed my moderator]) или в чате. Заранее благодарен!

[DaveSkender]

@turok2000 I'm not going to be able to write a custom indicator for you and cannot meet your needed schedule; however, I will likely add an example of how to write a custom indicator using this library (subscribe to #698 to follow) -- but again, even the example may take some time to write and share with the community.

I encourage others in this community to help out if they have time to support your unique needs.
