[VPCI] Volume Price Confirmation Indicator

version 1.1

I implemented Volume Price Confirmation Indicator (VPCI), invented by Buff Dormeier.
I applied the logic in the book "Investing with Volume Analysis".
Like MACD , it can also be used as a divergence or convergence method. The default value of whether to use this function is off.
Gold cross and dead cross points can also be marked. The default in this case is on.
It will be continuously updated. I will add the [four kinds of strategic sectors; sooner or later with the volume .

Thank you so much.

1. Removed the function to calculate by signal method like MACD
2. Improving cross-point display logic: Enter the upper and lower percentile values and calculate to display.
Golden Cross (buy recommendation) and Dead Cross (sell recommendation) outside the range.
example) if is ,
Golden Cross is calculated from the bottom percentages between 80% and 100%
and the target range of Death Cross is top percentages between 0% and 20%.
3. Added alpha coefficient
Let alpha be the value obtained by dividing the coefficient of variance of the price by the coefficient of variance of the volume.
I multiply it and calculate VPCI = alpha x VPC x VPR x VM to mitigate it if it overreacts to fluctuations in trading volume.
If the option is off, 1 is assigned to alpha and VPCI is calculated as the existing way.
* CV = std(values) / avg(values)

// 1. Assigned so that the product of short and long duration defaults is 50000.
// It's an experimental feature, so I put it in out of curiosity.
// Since the value of product has a constant constant value, the direction of the five VPCIs tends to converge.
// I expect to be able to predict more clearly in which direction the price will go.
// 2. Changed the default value of VPCIS graph to continuous graph of circle.
// 3. Assigned the 5 types of color classification as rainbow colors.
// 4. VPCI legend 1 to 5, respectively, set to RED, ORANGE, YELLOW, GREEN, BLUE as default values.
