Curvilinear Second-Order Regression

The Curvilinear Second Order Regression (CR) indicator plots a curve of the trend taking into consideration all prices. It is like a regular regression line, but curves slightly with the price trend.
The CR uses the second-order equation:
y = ax+ bx + cx^2
For calculation of coefficients a, b, c, see the code below.

Wilder Swing Index (SI) is a part of Wilder’s Swing Index System. In itself the SI is useless, it doesn’t generate any signals, but its formula combines factors that have great deal of interest.
The values of SI are used to form Accumulated Swing Index (ASI).

Wilder has determined that the five most important positive patterns in an uptrend are:
1. Today’s close is higher than the prior close.
2. Today’ close is higher than today’s open.
3. Today’s high is greater than the prior close.
4. Today’s low is greater that the prior close.
5. The prior close was above the prior open.
On a downtrend, these patterns are reversed.
SI combines these five factors, then scales the resulting value to fall between 100 and +100 as follows:
SI = 50x((Ct-Ct-1 + 0.5x(Ct - Ot)+0.25*(Ct-1-Ot-1))/R) x K/M
Where K is the largest of Ht – Ct-1 and Lt – Ct-1
M is the value of a limit move (in the Marketscope this value is 300, the same value is used in MT).
R is calculated from the following two steps:
1. Determine which of the largest of:
a. Ht – Ct-1
b. Lt – Ct-1
c. Ht – Lt
2. Calculate R to the corresponding formula:
a. R = (Ht – Ct-1) – 0.5(Lt – Ct-1) + 0.25(Ct-1 – Ot-1)
b. R = (Lt – Ct-1) – 0.5(Ht – Ct-1) + 0.25(Ct-1 – Ot-1)
c. R = (Ht – L1) + 0.25(Ct-1 – Ot-1)

Daily Raw Figure (DRF) measures the implied direction of the day’s trading.
DRF is calculated as:
DRF = (BP + SP)/(2x(high-low));
Where BP = high - open, SP = close – low.
The maximum value of 1 is reached when a market opens trading at the low and closes at the high. When the opposite occurs and the market opens at the high and closes on the lows, the DRF will be 0.

We have an updated KRI indicator in the new version of Marketscope II. Now it is drawn with lines, not as a histogram. Please find the old version below.
