cmo()

cmo: compute a Chande Momentum calculation

Examples

cmo for the close with a period of 50

result = stddev("Close", 50);

use built-in to create a Chande Momentum study

study("Hello World")
field = input("Field", "Close")

# Define the Period input for the study
period = input("Period", 50)
# Use the cmo builtin that calculates a Chande Momentum
cmo = cmo(field, period)

plot(cmo, color: "orange")

dataset()

dataset: pull quote values out of the (scrubbed) symbol values

Examples

close from the current quote

close = dataset("Close");

close from the previous quote

close = dataset("Close", -1);

implement a simple moving average

study("Simple MA")
field = input("Field", "field")
period = input("Period", 20)
sum = (length) ->
	total = 0
	while length
		value = dataset(field, -(--length))
		return null if not value?
		total += value
	total
total = sum period
if total?
	average = total / period
	plot average

ema()

ema: compute exponential moving average calculation

Examples

ema for the close with a period of 50

result = ema("Close", 50);

use built-in to create an exponential simple moving average study

fill()

Create parameters for {CIQ.prepareChannelFill}. Store in sd.scriptStates.

Example

Fill the area between two indicator lines

top = dataset("High");
bottom = dataset("Low");

topBand = plot(top);
bottomBand = plot(bottom);

fill(topBand, bottomBand, (color: "green"));

---

histogram()

Set the value in the dataset to create a histogram. There can only be a single histogram per study.

Examples

Simple histogram with default colors

histogram(field);

Histogram with custom positive & negative colors

histogram(field, (colorPositive: "#01ff01"), (colorNegative: "#ff0101"));

Histogram with custom increasing & decreasing colors

histogram(field, (colorIncreasing: "#0101ff"), (colorDecreasing: "#767600"), (opacity: 0.4));
