TUF_LOGICTUF_LOGIC: Three-Value Logic for Pine Script v6 The TUF_LOGIC library implements a robust three-valued logic system (trilean logic) for Pine Script v6, providing a formal framework for reasoning about uncertain or incomplete information in financial markets. By extending beyond binary True/False states to include an explicit "Uncertain" state, this library enables more nuanced algorithmic decision-making, particularly valuable in environments characterized by imperfect information. Core Architecture TUF_LOGIC offers two complementary interfaces for working with trilean values: Enum-Based API (Recommended): Leverages Pine Script v6's enum capabilities with Trilean.True , Trilean.Uncertain , and Trilean.False for improved type safety and performance. Integer-Based API (Legacy Support): Maintains compatibility with existing code using integer values 1 (True), 0 (Uncertain), and -1 (False). Fundamental Operations The library provides type conversion methods for seamless interaction between integer representation and enum types ( to_trilean() , to_int() ), along with validation functions to maintain trilean invariants. Logical Operators TUF_LOGIC extends traditional boolean operators to the trilean domain with NOT , AND , OR , XOR , and EQUALITY functions that properly handle the Uncertain state according to the principles of three-valued logic. The library implements three different implication operators providing flexibility for different logical requirements: IMP_K (Kleene's approach), IMP_L (Łukasiewicz's approach), and IMP_RM3 (Relevant implication under RM3 logic). Inspired by Tarski-Łukasiewicz's modal logic formulations, TUF_LOGIC includes modal operators: MA (Modal Assertion) evaluates whether a state is possibly true; LA (Logical Assertion) determines if a state is necessarily true; and IA (Indeterminacy Assertion) identifies explicitly uncertain states. The UNANIMOUS operator evaluates trilean values for complete agreement, returning the consensus value if one exists or Uncertain otherwise. This function is available for both pairs of values and arrays of trilean values. Practical Applications TUF_LOGIC excels in financial market scenarios where decision-making must account for uncertainty. It enables technical indicator consensus by combining signals with different confidence levels, supports multi-timeframe analysis by reconciling potentially contradictory signals, enhances risk management by explicitly modeling uncertainty, and handles partial information systems where some data sources may be unreliable. By providing a mathematically sound framework for reasoning about uncertainty, TUF_LOGIC elevates trading system design beyond simplistic binary logic, allowing for more sophisticated decision-making that better reflects real-world market complexity.

Three (3)-Bar and Four (4)-Bar Plays StrategyThis strategy analyzes the three and four-bar play which is when price action has a wide igniting bar that has a full body, then one or two narrow bars which have a relatively equal high for long plays and relatively equal low for short plays, then a continuation bar. You should not take plays that will encounter resistance. The stop loss is placed for long plays below the 2nd bar (or 3rd bar for 4-bar play). This is commonly used on 1m, 2m, 5m, and 10m charts. Jared Wesley is one of the more notable traders that use this setup. You can edit as an input the start date, end date, igniting bar size, the body percentage of the igniting bar, the relative equality of the 2nd bar (and 3rd bar for 4-bar play) compared to the igniting bar, and profit multiplier.

Relative Falling three Methods IndicatorAbstract This script measure the related speed between rising and falling. This script can replace binary Falling Three Methods detector and, report continuous value and estimate potential trend direction. My suggestion of using this script is combining it with trading emotion. Introduction Falling Three Methods (F3M) is a candlestick pattern. Many trading courses say traders can regard it as predicting falling will continue. However, it is not easy to see perfect Falling Three Methods pattern from charts. Therefore, we need an alternative method to measure it. We can use the observation that falling is faster than rising during those time. When falling is faster than rising, some long ( buy , call , higher , upper ) position owners may worry the price will fall very much suddenly. When rising is faster than falling, some traders may worry they may miss buy opportunities. Computing Related Falling Three Methods Indicator (1) The value of rising and falling In this script, open price is replaced with previous close price. If the previous price is equal to the close price, than both rising and falling are equal to high-low. If the previous price is lower than the close price, than the falling value becomes smaller, high-close+previous-low. If the previous price is higher than the close price, than the rising value becomes smaller, high-previous+close-low. (2) Area of value (aov) Area of value is equal to highest-lowest. The previous close price is included. (3) Compute weight and filter noise We need a threshold for the noise filter. The default setting is aov/length, where length means how many days are counted. When a rising or falling value <= threshold, it is not counted. When a rising or falling value > threshold, the counted value = original value - threshold and its weight = min ( counted value , threshold ) (4) compute speed Rising speed = sum ( counted rising value ) / sum ( rising weight ) Falling speed = sum ( counted falling value ) / sum ( falling weight ) (5) Final result Final result = Rising speed / ( Rising speed + Falling speed ) * 100 - 50 I move the middle level to 0 because 0 axis is always visible unless you cannot see negative values or you cannot see positive values. Parameters Length : how many days are counted. The default value is 16 just because 16=4*4, using binary characteristic. Multi : the multiplier of noise threshold. Threshold applied = default threshold * multi src : current not used Conclusion Related Falling Three Methods Indicator can measure the related speed between rising and falling. I hope this indicator can help us to evaluate the possibility of trend continue or reversal and potential breakout direction. After all, we care how trading emotion control the price movement and therefore we can take advantage to it.

Combo Backtest 123 Reversal & D_Three Ten OscThis is combo strategies for get a cumulative signal. First strategy This System was created from the Book "How I Tripled My Money In The Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies. The strategy buys at market, if close price is higher than the previous close during 2 days and the meaning of 9-days Stochastic Slow Oscillator is lower than 50. The strategy sells at market, if close price is lower than the previous close price during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50. Second strategy TradeStation does not allow the user to make a Multi Data Chart with a Tick Bar Chart and any other type a chart. This indicator allows the user to plot a daily 3-10 Oscillator on a Tick Bar Chart or any intraday interval. Walter Bressert's 3-10 Oscillator is a detrending oscillator derived from subtracting a 10 day moving average from a 3 day moving average. The second plot is an 16 day simple moving average of the 3-10 Oscillator. The 16 period moving average is the slow line and the 3/10 oscillator is the fast line. For more information on the 3-10 Oscillator see Walter Bressert's book "The Power of Oscillator/Cycle Combinations" WARNING: - For purpose educate only - This script to change bars colors.

Three Line Break Backtest This is a modified version of the three line break price representation. It is composed with 2 lines made of Close price values forming a “cloud”. If the trend is bullish and the price breach the lower level of the green cloud, a new bearish trend is taking place. If the current trend is bearish and the price breakout the upper band of the cloud, a new bullish trend is forming. This is a “price action” indicator, signals may be filtered by long term trend analysis with other indicators such as Supertrend for instance.
