Fast Fourier Transform [ScorsoneEnterprises]The SCE Fast Fourier Transform (FFT) is a tool designed to analyze periodicities and cyclical structures embedded in price. This is a Fourier analysis to transform price data from the time domain into the frequency domain, showing the rhythmic behaviors that are otherwise invisible on standard charts. Instead of merely observing raw prices, this implementation applies the FFT on the logarithmic returns of the asset: Log Return(𝑚) = log⁡(close / close ) This ensures stationarity and stabilizes variance, making the analysis statistically robust and less influenced by trends or large price swings. For a user-defined lookback window 𝑁: Each frequency component 𝑘 is computed by summing real and imaginary projections of log-returns multiplied by complex exponential functions: 𝑒^−𝑖𝜃 = cos⁡(𝜃)−𝑖sin(𝜃) where: θ = 2πkm / N ​he result is the magnitude spectrum, calculated as: Magnitude(𝑘) = sqrt(Real_Sum(𝑘)^2 + Imag_Sum(𝑘)^2) This spectrum represents the strength of oscillations at each frequency over the lookback period, helping traders identify dominant cycles. Visual Analysis & Interpretation To give traders context for the FFT spectrum’s values, this script calculates: 25th Percentile (Purple Line) Represents relatively low cyclical intensity. Values below this threshold may signal quiet, noisy, or trendless periods. 75th Percentile (Red Line) Represents heightened cyclical dominance. Values above this threshold may indicate significant periodic activity and potential trend formation or rhythm in price action. The FFT magnitude of the lowest frequency component (index 0) is plotted directly on the chart in teal. Observing how this signal fluctuates relative to its percentile bands provides a dynamic measure of cyclical market activity. Chart examples In this NYSE:CL chart, we see the regime of the price accurately described in the spectral analysis. We see the price above the 75th percentile continue to trend higher until it breaks back below. In long trending markets like NYSE:PL has been, it can give a very good explanation of the strength. There was confidence to not switch regimes as we never crossed below the 75th percentile early in the move. The script is also usable on the lower timeframes. There is no difference in the usability from the different timeframes. Script Parameters Lookback Value (N) Default: 30 Defines how many bars of data to analyze. Larger N captures longer-term cycles but may smooth out shorter-term oscillations.

我的策略 The specific implementation of the dominant_cycle function needs to be done using ta.ht_dominant_cycle_period or by calculating the rate of change of the phase, which requires detailed technical processing in actual coding. How to use the "Market Mathieu Oscillator": • Green background (stable zone): The market is likely to be in a consolidation or mean reversion state. Trend strategies are riskier, while range trading or option seller strategies may be more dominant. • Yellow background (warning zone): The market has entered a "flammable" state where resonance may occur. Counter-trend trading should be reduced, and preparations for potential breakthroughs should be started, tightening stops. • Red background (unstable/resonance zone): **Highest alert! ** This shows that the market is not only "flammable", but also has a "spark" (strong driving force). This is the stage where the trend is most likely to accelerate and sustain itself. Counter-trend operations should be strictly avoided, and trend-following strategies should be actively adopted. • Q Oscillator: • The rising q value means that emotions are moving to extremes and the "fuel" of the trend is increasing. • The q-value is falling, indicating that sentiment is returning to neutrality and the "fuel" of the trend is decreasing, which may indicate the exhaustion of the trend or the beginning of consolidation. • When the q-value exceeds the red threshold line, it indicates that the driving force is extremely strong, which is one of the necessary conditions for entering the red background. The "Market Mathieu Oscillator" is an innovative attempt to transform a profound physical and financial theory into an intuitive decision-making aid available on TradingView through a proxy and simplified approach. It cannot make precise quantitative predictions like theoretical models, but it provides a whole new dimension to observe the market: it no longer focuses solely on the price itself, but on the relationship between the "force" that drives the price and the "rhythm" of the market itself. Through this lens, traders can better understand when the market may turn from stability to turbulence, and make more strategic decisions.

EMAs + LSMA Cross Alert (Mejorado)his indicator is designed to identify buy and sell signals based on the behavior of multiple exponential moving averages (EMAs) and a Least Squares Moving Average (LSMA). It includes 5 EMAs and one LSMA, with visual and alert features. 📌 Components: EMA 4 (purple) EMA 9 (Fuchsia) EMA 21 (blue) EMA 50 (Green) EMA 200 (maroon) LSMA 30 (Orange) 🔍 Signal Logic: ✅ Buy Signal: The LSMA (30) must be below both EMA 4 and EMA 9. A bullish crossover occurs: EMA 4 crosses above EMA 9. Only one signal is triggered per crossover, avoiding repeated alerts during trend continuation. ❌ Sell Signal: The LSMA (30) must be above both EMA 4 and EMA 9. A bearish crossover occurs: EMA 4 crosses below EMA 9. Only one signal is triggered per crossover, avoiding repeated alerts during trend continuation. 🖥️ Visual Features: Option to show/hide each EMA and the LSMA. Buy/Sell markers appear at cross points. A white background highlight marks the candle where the signal occurs (optional). Visuals scale dynamically with the chart zoom and axes. 🔔 Alerts: Custom alert conditions for Buy and Sell. Alerts can trigger push notifications to the TradingView mobile app, email, or webhook. Configured to avoid repeating alerts unless the trend resets and a new valid crossover occurs.

Random Coin Toss Strategy📌 Overview This strategy is a probability-based trading simulation that randomly decides trade direction using a coin-toss mechanism and executes trades with a customizable risk-reward ratio. It's designed primarily for testing entry frequency and risk dynamics, not predictive accuracy. 🎯 Core Concept Every N bars (configurable), the strategy performs a pseudo-random coin toss. Based on the result: If heads → Buy If tails → Sell Once a position is opened, it sets a Stop-Loss (SL) and Take-Profit (TP) based on a multiple of the current ATR (Average True Range) value. ⚙️ Configurable Inputs ATR Length Period for ATR calculation, determines volatility basis. SL Multiplier SL distance = ATR × multiplier (e.g., 1.0 means 1x ATR) . TP Multiplier TP distance = ATR × multiplier (e.g., 2.0 = 2x ATR) . Entry Frequency Bars to wait between each new coin toss decision. Show TP/SL Zones Toggle on/off for drawing visual TP and SL zones. Box Size Number of bars used to define the width of the TP/SL boxes. 🔁 Entry & Exit Logic Entry: Happens only when no current position exists and it's the correct bar interval. Entry direction is randomly decided. Exit: Positions exit at either: Take-Profit (TP) level Stop-Loss (SL) level Both are calculated using the configured ATR-based distances. 🖼️ Visual Features TP and SL zones: Rendered as shaded rectangles (boxes) only once per trade. Green box for TP zone, red box for SL zone. Automatically deleted and redrawn for each new trade to avoid chart clutter. ATR Display Table: A minimal info table at the top-right shows the current ATR value. Updates every few bars for performance. 🧪 Use Cases Ideal for risk-reward modeling, strategy prototyping, and understanding how volatility-based SL/TP behavior affects results. Great for backtesting frequency, RR tweaks (e.g., 2:5 or 3:1), and execution structure in random conditions. ⚠️ Disclaimer Since the trade direction is random, this script is not meant for predictive trading but serves as a powerful experiment framework for studying how SL, TP, and volatility interact with random chance in a controlled, repeatable system.
