Индикатор Heiken Ashi zero lag EMA v1.1 by JustUncleL использует в своих выводах несколько показателей.
необходимо разобрать все показатели в математические функции, и в дальнейшем все это описать на Python.
общий смысл:
-есть свое приложение написанное на Python(Back-end) и его визуальная часть(Front-end) JavaScript на по сути тот же Tradingview, необходимо перенести туда индикатор Heiken Ashi zero lag EMA v1.1 by JustUncleL.
есть исходный код индикатора Heiken Ashi zero lag EMA v1.1 by JustUncleL взятый с Tradingview:

// Title: Heiken Ashi with non lag dot by JustUncleL
// Author: JustUncleL
// Version: 0.2
// Date: 5-feb-2016
//
// Description:
// This Alert indicator utilizes the Heiken Ashi with non lag EMA was a scalping and intraday trading system
// that has been adapted also for trading with binary options high/low. There is also included
// filtering on MACD direction and trend direction as indicated by two MA: smoothed MA(11) and EMA(89).
// The the Heiken Ashi candles are great as price action trending indicator, they shows smooth strong
// and clear price fluctuations.
//
// Financial Markets: any.
// Optimsed settings for 1 min, 5 min and 15 min Time Frame;
// Expiry time for Binary options High/Low 3-6 candles.
//
// Indicators used in calculations:
// - Exponential moving average, period 89
// - Smoothed moving average, period 11
// - Non lag EMA, period 20
// - MACD 2 colour (13,26,9)
//
//
// Generate Alerts use the following Trading Rules
// Heiken Ashi with non lag dot
// Trade only in direction of the trend.
// UP trend moving average 11 period is above Exponential moving average 89 period,
// Doun trend moving average 11 period is below Exponential moving average 89 period,
//
// CALL Arrow appears when:
// Trend UP SMA11>EMA89 (optionally disabled),
// Non lag MA blue dot and blue background.
// Heike ashi green color.
// MACD 2 Colour histogram green bars (optional disabled).
//
// PUT Arrow appears when:
// Trend UP SMA11<EMA89 (optionally disabled),
// Heike ashi red color.
// Non lag MA red dot and red background
// MACD 2 colour histogram red bars (optionally disabled).
//
// Modifications:
// 0.2 - Added MACD and directional filtering.
// Added background highlighting of Zero Lag EMA dots.
// Replaced Bollinger Band squeeze indicator with MACD 2 colour
// 0.1 - Original version.
