cloudTheory

Library "cloudTheory"

// OBJECTTIVE: A Combination of EMA to Draw Cloud Pattern on Chart
//
// The "2-EMA Line System" is one of the most oldest and durable
// frameworks in technical analysis where we plot one "fast" (short)
// and one "slow" (long) exponential moving average line on the same
// chart and their relationships determine the state of the security.

drawCloud(fastLength, slowLength, src)
Parameters:
fastLength (simple int): - Fast EMA Length, the shorter length which
typically determines the current rhythm of the security.

slowLength (simple int): - Slow EMA Length, the longer length which
determines the underlying drift of the security.

src (float): - Which value of the candle should be used to calculate
the moving average; defaults to candle close value.

Returns: [emaFast, emaSlow, isBullish, isBearish, isNeutral] - EMA
Values and the flags to determine the current sentiment.

drawCloud(fastLength, slowLength, src)
Parameters:
fastLength (simple int): - Fast EMA Length, the shorter length which
typically determines the current rhythm of the security.

cloudTheory is a visualization extension of "2-EMA Line System", which can be used to provide visual confirmation based on the price action of the underlying. In addition, the library provides methods for calculating momentum using (I) the traditional method, and (II) Baz et al. CTA method.

✨ Getting Started

The public (open-source) library is available at TradingView, and a rich documentation and usage guide is available at blog website. Import the library as below:

Pine Script®

Then you can directly create editable fields and value control fields to implement the logic. To design the color schemes, it is recommended to use a three-toned system, and cross-over markings can be implemented as follows:
