EMAs: 10,20 Hello this is a script that seeks to increase a bit the number of indicators used in the free version. its use is to know if a trend continues or will change, it is a very used and simple but efficient system. If the distance between the lines remains constant then it indicates or gives an indication that the trend continues but if they are cut it indicates or gives an indication of change of interest. sorry for my bad english but I speak spanish

Mythical EMAs + Dynamic VWAP BandThis indicator titled "Mythical EMAs + Dynamic VWAP Band." It overlays several volatility-adjusted Exponential Moving Averages (EMAs) on the chart, along with a Volume Weighted Average Price (VWAP) line and a dynamic band around it. Additionally, it uses background coloring (clouds) to visualize bullish or bearish trends, with intensity modulated by the price's position relative to the VWAP. The EMAs are themed with mythical names (e.g., Hermes for the 9-period EMA), but this is just stylistic flavoring and doesn't affect functionality. I'll break it down section by section, explaining what each part does, how it works, and its purpose in the context of technical analysis. This indicator is designed for traders to identify trends, momentum, and price fairness relative to volume-weighted averages, with volatility adjustments to make the EMAs more responsive in volatile markets. ### 1. **Volatility Calculation (ATR)** ```pine atrLength = 14 volatility = ta.atr(atrLength) ``` - **What it does**: Calculates the Average True Range (ATR) over 14 periods (a common default). ATR measures market volatility by averaging the true range (the greatest of: high-low, |high-previous close|, |low-previous close|). - **Purpose**: This volatility value is used later to dynamically adjust the EMAs, making them more sensitive in high-volatility conditions (e.g., during market swings) and smoother in low-volatility periods. It helps the indicator adapt to changing market environments rather than using static EMAs. ### 2. **Custom Mythical EMA Function** ```pine mythical_ema(src, length, base_alpha, vol_factor) => alpha = (2 / (length + 1)) * base_alpha * (1 + vol_factor * (volatility / src)) ema = 0.0 ema := na(ema ) ? src : alpha * src + (1 - alpha) * ema ema ``` - **What it does**: Defines a custom function to compute a modified EMA. - It starts with the standard EMA smoothing factor formula: `2 / (length + 1)`. - Multiplies it by a `base_alpha` (a user-defined multiplier to tweak responsiveness). - Adjusts further for volatility: Adds a term `(1 + vol_factor * (volatility / src))`, where `vol_factor` scales the impact, and `volatility / src` normalizes ATR relative to the source price (making it scale-invariant). - The EMA is then calculated recursively: If the previous EMA is NA (e.g., at the start), it uses the current source value; otherwise, it weights the current source by `alpha` and the prior EMA by `(1 - alpha)`. - **Purpose**: This creates "adaptive" EMAs that react faster in volatile markets (higher alpha when volatility is high relative to price) without overreacting in calm periods. It's an enhancement over standard EMAs, which use fixed alphas and can lag in choppy conditions. The mythical theme is just naming—functionally, it's a volatility-weighted EMA. ### 3. **Calculating the EMAs** ```pine ema9 = mythical_ema(close, 9, 1.2, 0.5) // Hermes - quick & nimble ema20 = mythical_ema(close, 20, 1.0, 0.3) // Apollo - short-term foresight ema50 = mythical_ema(close, 50, 0.9, 0.2) // Athena - wise strategist ema100 = mythical_ema(close, 100, 0.8, 0.1) // Zeus - powerful oversight ema200 = mythical_ema(close, 200, 0.7, 0.05) // Kronos - long-term patience ``` - **What it does**: Applies the custom EMA function to the close price with varying lengths (9, 20, 50, 100, 200 periods), base alphas (decreasing from 1.2 to 0.7 for longer periods to make shorter ones more responsive), and volatility factors (decreasing from 0.5 to 0.05 to reduce volatility influence on longer-term EMAs). - **Purpose**: These form a multi-timeframe EMA ribbon: - Shorter EMAs (e.g., 9 and 20) capture short-term momentum. - Longer ones (e.g., 200) show long-term trends. - Crossovers (e.g., short EMA crossing above long EMA) can signal buy/sell opportunities. The volatility adjustment makes them "mythical" by adding dynamism, potentially improving signal quality in real markets. ### 4. **VWAP Calculation** ```pine vwap_val = ta.vwap(close) // VWAP based on close price ``` - **What it does**: Computes the Volume Weighted Average Price (VWAP) using the built-in `ta.vwap` function, anchored to the close price. VWAP is the average price weighted by volume over the session (resets daily by default in Pine Script). - **Purpose**: VWAP acts as a benchmark for "fair value." Prices above VWAP suggest bullishness (buyers in control), below indicate bearishness (sellers dominant). It's commonly used by institutional traders to assess entry/exit points. ### 5. **Plotting EMAs and VWAP** ```pine plot(ema9, color=color.fuchsia, title='EMA 9 (Hermes)') plot(ema20, color=color.red, title='EMA 20 (Apollo)') plot(ema50, color=color.orange, title='EMA 50 (Athena)') plot(ema100, color=color.aqua, title='EMA 100 (Zeus)') plot(ema200, color=color.blue, title='EMA 200 (Kronos)') plot(vwap_val, color=color.yellow, linewidth=2, title='VWAP') ``` - **What it does**: Overlays the EMAs and VWAP on the chart with distinct colors and titles for easy identification in TradingView's legend. - **Purpose**: Visualizes the EMA ribbon and VWAP line. Traders can watch for EMA alignments (e.g., all sloping up for uptrend) or price interactions with VWAP. ### 6. **Dynamic VWAP Band** ```pine band_pct = 0.005 vwap_upper = vwap_val * (1 + band_pct) vwap_lower = vwap_val * (1 - band_pct) p1 = plot(vwap_upper, color=color.new(color.yellow, 0), title="VWAP Upper Band") p2 = plot(vwap_lower, color=color.new(color.yellow, 0), title="VWAP Lower Band") fill_color = close >= vwap_val ? color.new(color.green, 80) : color.new(color.red, 80) fill(p1, p2, color=fill_color, title="Dynamic VWAP Band") ``` - **What it does**: Creates a band ±0.5% around the VWAP. - Plots the upper/lower bands with full transparency (color opacity 0, so lines are invisible). - Fills the area between them dynamically: Semi-transparent green (opacity 80) if close ≥ VWAP (bullish bias), red if below (bearish bias). - **Purpose**: Highlights deviations from VWAP visually. The color change provides an at-a-glance sentiment indicator—green for "above fair value" (potential strength), red for "below" (potential weakness). The narrow band (0.5%) focuses on short-term fairness, and the fill makes it easier to spot than just the line. ### 7. **Trend Clouds with VWAP Interaction** ```pine bullish = ema9 > ema20 and ema20 > ema50 bearish = ema9 < ema20 and ema20 < ema50 bullish_above_vwap = bullish and close > vwap_val bullish_below_vwap = bullish and close <= vwap_val bearish_below_vwap = bearish and close < vwap_val bearish_above_vwap = bearish and close >= vwap_val bgcolor(bullish_above_vwap ? color.new(color.green, 50) : na, title="Bullish Above VWAP") bgcolor(bullish_below_vwap ? color.new(color.green, 80) : na, title="Bullish Below VWAP") bgcolor(bearish_below_vwap ? color.new(color.red, 50) : na, title="Bearish Below VWAP") bgcolor(bearish_above_vwap ? color.new(color.red, 80) : na, title="Bearish Above VWAP") ``` - **What it does**: Defines trend conditions based on EMA alignments: - Bullish: Shorter EMAs stacked above longer ones (9 > 20 > 50, indicating upward momentum). - Bearish: The opposite (downward momentum). - Sub-conditions combine with VWAP: E.g., bullish_above_vwap is true only if bullish and price > VWAP. - Applies background colors (bgcolor) to the entire chart pane: - Strong bullish (above VWAP): Green with opacity 50 (less transparent, more intense). - Weak bullish (below VWAP): Green with opacity 80 (more transparent, less intense). - Strong bearish (below VWAP): Red with opacity 50. - Weak bearish (above VWAP): Red with opacity 80. - If no condition matches, no color (na). - **Purpose**: Creates "clouds" for trend visualization, enhanced by VWAP context. This helps traders confirm trends—e.g., a strong bullish cloud (darker green) suggests a high-conviction uptrend when price is above VWAP. The varying opacity differentiates signal strength: Darker for aligned conditions (trend + VWAP agreement), lighter for misaligned (potential weakening or reversal). ### Overall Indicator Usage and Limitations - **How to use it**: Add this to a TradingView chart (e.g., stocks, crypto, forex). Look for EMA crossovers, price bouncing off EMAs/VWAP, or cloud color changes as signals. Bullish clouds with price above VWAP might signal buys; bearish below for sells. - **Strengths**: Combines momentum (EMAs), volume (VWAP), and volatility adaptation for a multi-layered view. Dynamic colors make it intuitive. - **Limitations**: - EMAs lag in ranging markets; volatility adjustment helps but doesn't eliminate whipsaws. - VWAP resets daily (standard behavior), so it's best for intraday/session trading. - No alerts or inputs for customization (e.g., changeable lengths)—it's hardcoded. - Performance depends on the asset/timeframe; backtest before using. - **License**: Mozilla Public License 2.0, so it's open-source and modifiable.

Infinite EMA with Alpha Control♾️ Infinite EMA with Alpha Control What Makes This EMA "Infinite"? Unlike traditional EMA indicators that are limited to typical periods (1-5000), this Infinite EMA breaks all boundaries. You can create EMAs with periods of 1,000, 10,000, or even 1,000,000 bars - that's why it's called "infinite"! Also Infinite EMA starts working immediately from the very first bar on your chart Why This EMA is "Infinite": 1. Mathematically: When N → ∞, alpha → 0, meaning infinitely long "memory" 2. Practically: You can set any period - even 100,000 bars 3. Flexibility: Alpha allows precise control over the "forgetting speed" How Does It Work? The magic lies in the Alpha parameter. While regular EMAs use fixed formulas, this indicator gives you direct control over the EMA's "memory" through Alpha values: • High Alpha (0.1-0.2): Fast reaction, short memory • Medium Alpha (0.01-0.05): Balanced response • Low Alpha (0.0001-0.001): Extremely slow reaction, very long memory • Ultra-low Alpha (0.000001): Almost frozen in time The Mathematical Formula: Alpha = 2 / (Period + 1) This means you can achieve any EMA period by adjusting Alpha, giving you infinite flexibility! Expanded "Infinite EMA" Table: Period EMA (N) - Alpha (Rounded) - Alpha (Exact) - Description 10 - 0.1818 - 0.181818... - Fast EMA 20 - 0.0952 - 0.095238... - Short-term 50 - 0.0392 - 0.039215... - Medium-term 100 - 0.0198 - 0.019801... - Long-term 200 - 0.0100 - 0.009950... - Standard long-term 500 - 0.0040 - 0.003996... - Very long-term 1,000 - 0.0020 - 0.001998... - Super long-term 2,000 - 0.0010 - 0.000999... - Ultra long-term 5,000 - 0.0004 - 0.000399... - Mega long-term 10,000 - 0.0002 - 0.000199... - Giga long-term 25,000 - 0.00008 - 0.000079... - Century-scale EMA 50,000 - 0.00004 - 0.000039... - Practically motionless 100,000 - 0.00002 - 0.000019... - "Glacial" EMA 500,000 - 0.000004 - 0.000003... - Geological timescale 1,000,000 - 0.000002 - 0.000001... - Approaching constant 5,000,000 - 0.0000004 - 0.0000003... - Virtually static 10,000,000 - 0.0000002 - 0.0000001... - Nearly flat line 100,000,000 - 0.00000002 - 0.00000001... - Mathematical infinity Formula: Alpha = 2/(N+1) where N is the EMA period Key Features: Dual EMA System: Run fast and slow EMAs simultaneously Crossover Signals: Automatic buy/sell signals with customizable alerts Alpha Control: Direct mathematical control over EMA behavior Infinite Periods: From 1 to 100,000,000+ bars Visual Customization: Colors, fills, backgrounds, signal sizes Instant Start: Works accurately from the very first bar Update Intervals: Control calculation frequency for noise reduction Why Choose Infinite EMA? 1. Unlimited Flexibility: Any period you can imagine 2. Mathematical Precision: Direct alpha control for exact behavior 3. Professional Grade: Suitable for all trading styles 4. Easy to Use: Simple settings with powerful results 5. No Warm-up Period: Accurate values from bar #1 Simple Explanation: Think of EMA as a "memory system": • High Alpha = Short memory (forgets quickly, reacts fast) • Low Alpha = Long memory (remembers everything, moves slowly) With Infinite EMA, you can set the "memory length" to anything from seconds to centuries! ⚡ Instant Start Feature - EMA from First Bar Immediate Calculation from Bar #1 Unlike traditional EMA indicators that require a "warm-up period" of N bars before showing accurate values, Infinite EMA starts working immediately from the very first bar on your chart. How It Works: Traditional EMA Problem: • Standard 200-period EMA: Needs 200+ bars to become accurate • First 200 bars: Shows incorrect/unstable values • Result: Large portions of historical data are unusable Infinite EMA Solution: Bar #1: EMA = Current Price (perfect starting point) Bar #2: EMA = Alpha × Price + (1-Alpha) × Previous EMA Bar #3: EMA = Alpha × Price + (1-Alpha) × Previous EMA ...and so on Key Benefits: No Warm-up Period: Start trading signals from day one Full Chart Coverage: Every bar has a valid EMA value Historical Accuracy: Backtesting works on entire dataset New Markets: Works perfectly on newly listed assets Short Datasets: Effective even with limited historical data Practical Impact: Scenario Traditional EMA Infinite EMA New cryptocurrency Unusable for first 200 days ✅ Works from day 1 Limited data (< 200 bars) Inaccurate values ✅ Fully functional Backtesting Must skip first 200 bars ✅ Test entire history Real-time trading Wait for stabilization ✅ Trade immediately Technical Implementation: if barstate.isfirst EMA := currentPrice // Perfect initialization else EMA := alpha × currentPrice + (1-alpha) × previousEMA This smart initialization ensures mathematical accuracy from the very first calculation, eliminating the traditional EMA "ramp-up" problem. Why This Matters: For Backesters: Use 100% of available data For Live Trading: Get signals immediately on any timeframe For Researchers: Analyze complete datasets without gaps Bottom Line: Infinite EMA is ready to work the moment you add it to your chart - no waiting, no warm-up, no exceptions! Unlike traditional EMAs that require a "warm-up period" of 200+ bars before showing accurate values, Infinite EMA starts working immediately from bar #1. This breakthrough eliminates the common problem where the first portion of your chart shows unreliable EMA data. Whether you're analyzing a newly listed cryptocurrency, working with limited historical data, or backtesting strategies, every single bar provides mathematically accurate EMA values. No more waiting periods, no more unusable data sections - just instant, reliable trend analysis from the moment you apply the indicator to any chart. 🔄 Update Interval Bars Feature The Update Interval feature allows you to control how frequently the EMA recalculates, providing flexible noise filtering without changing the core mathematics. Set to 1 for standard behavior (updates every bar), or increase to 5-10 for smoother signals that update less frequently. Higher intervals reduce market noise and false signals but introduce slightly more lag. This is particularly useful on volatile timeframes where you want the EMA's directional bias without every minor price fluctuation affecting the calculation. Perfect for swing traders who prefer cleaner, more stable trend lines over hyper-responsive indicators. Conclusion The Infinite EMA transforms the traditional EMA from a fixed-period tool into a precision instrument with unlimited flexibility. By understanding the Alpha-Period relationship, traders can create custom EMAs that perfectly match their trading style, timeframe, and market conditions. The "infinite" nature comes from the ability to set any period imaginable - from ultra-fast 2-bar EMAs to glacially slow 10-million-bar EMAs, all controlled through a single Alpha parameter. ________________________________________ Whether you're a beginner looking for simple trend following or a professional researcher analyzing century-long patterns, Infinite EMA adapts to your needs. The power of infinite periods is now in your hands! 🚀 Go forward to the horizon. When you reach it, a new one will open up. - J. P. Morgan
