Spearman's Rank Correlation is a non-parametric method used in order to make statistical studies of relationship between variables. 이 경우, the factual degree of parallelism between two numeric sequences will be detected.
The practical calculation of Spearman's Rank Correlation includes the following stages:
1) pair each indication with its number (rank) and rank them from the highest to the lowest or vice versa;
2) subtract the two sets of ranks of each pair of values to be compared;
3) square each difference and add the obtained values;
4) calculate the rank correlation from the following formula:
,
어디 is the sum of squares of rank differences, is the number of paired observations.
When employing the rank correlation, one conditionally estimates the correlation ratio between indications considering the values being equal to or below 0.3 to be the indications of low correlation ratio, whereas the values between 0.4 그리고 0.7 are considered to indicate a moderate correlation ratio, values above 0.7 - to indicate a high correlation ratio.
Spearman's Rank Correlation is a little less powerful than the Parametric Correlation.
It is reasonable to use the rank correlation when there is just a small amount of observations. This method can be used for both numerical data and in the cases, when the registered values are detected by attributes of various intensity. The source of the above description was found 여기. This indicator is one of oscillators. 하지만, being compared to stochastic oscillator, it is smoother. 게다가, it does not delay in pivot points. The parameter of direction means sorting from the highest to the lowest value (진실) or from the lowest to the highest value (거짓). The value of 진실 shows a more usual picture, whereas 거짓 produces an inverted image. Parameter CalculatedBars is introduced in order to limit the amount of bars under calculation, to save CPU resources (though that wasn't needed). Zero value of this parameter means that calculations will be performed for all history available. Parameter Maxrange = 30 sets the maximum calculation period. This parameter was introduced in order to save resources, 또한, so maybe somebody will need it. |

I have tried this indicator and it will not even load. I even tried recompiling it, but it will not load on a chart. I'm using MT4 Ver. 4.0, 짓다 500. Is anyone else having this problem? Is there a fix?

I use this indicator and It has given me VERY NICE RESULTS. 기간: 5중, 쌍: EURUSD. I trade the first three hours in London and New York markets to ensure volume. I have in mind the levels +0.9 (Overbought) 그리고 -0.9 (Oversold), so that when it breaks down after hitting +0.9 팔다, so when it breaks up after hitting -0.9 구입하다. NO REPAINTS !!!

Great indicator. It would be great to have a spearman auto-correlation, returning a value between -1 그리고 +1. Being overbought > 0.75 and oversold < -0.75.
