Special relations

Also seen as: special strings, pattern relations, cross relations

How does Fincanva handle it?

Six filters carry special relations — SMA, Bollinger Bands, Stochastic, Mkt SMA, Buffet Indicator and Sec SMA, placed in the filter taxonomy — and on them the relations replace the numeric operators rather than sitting beside them, each its own choice in the filter's editor. A special relation never takes a threshold value; where it takes a number at all, that number is a time window, not a level, and the filter's lag, period, and multiplier inputs still apply. The crossings ask whether a price or an oscillator line crossed within the last N trading days; Price Above and Price Below ask which side of the line the price sits on now; the five valuation bands place the market's valuation reading on the Buffet Indicator filter in one of five mutually exclusive bands. Fincanva describes what these relations detect; it does not rate a crossing as bullish or bearish for your purposes, and a relation being true is not a signal to act. Every relation, its chip and its window are in Screen for a crossing or a valuation band.

Is Crosses Above the same as a golden cross?

No — Crosses Above tests the price against one moving average, while a golden cross is conventionally a faster moving average crossing above a slower one. The two are related signals but not the same test: with Crosses Above there is one line on the chart and the price crosses it; with a golden cross there are two lines and they cross each other.

The relations that do compare two lines to each other are the Stochastic filter's Fast/Slow pair, and there the two lines are the oscillator's fast and slow lines, not a pair of moving averages. So "golden cross" is a useful mental picture for what Crosses Above signals, and the wrong description of what it measures.
