Function

Weierstrass Function (Fractal Cycles)THE WEIERSTRASS FUNCTION f(x) = ∑(n=0)^∞ a^n * cos(b^n * π * x) The Weierstrass Function is the sum of an infinite series of cosine functions, each with increasing frequency and decreasing amplitude. This creates powerful multi-scale oscillations within the range ⬍(-2;+2), resembling a system of self-repetitive patterns. You can zoom into any part of the output and observe similar proportions, mimicking the hidden order behind the irregularity and unpredictability of financial markets. IT DOESN’T RELY ON ANY MARKET DATA, AS THE OUTPUT IS BASED PURELY ON A MATHEMATICAL FORMULA! This script does not provide direct buy or sell signals and should be used as a tool for analyzing the market behavior through fractal geometry. The function is often used to model complex, chaotic systems, including natural phenomena and financial markets. APPLICATIONS: Timing Aspect: Identifies the phases of market cycles, helping to keep awareness of frequency of turning points Price-Modeling features: The Amplitude, frequency, and scaling settings allow the indicator to simulate the trends and oscillations. Its nowhere-differentiable nature aligns with the market's inherent uncertainty. The fractured oscillations resemble sharp jumps, noise, and dips found in volatile markets. SETTINGS Amplitude Factor (a): Controls the size of each wave. A higher value makes the waves larger. Frequency Factor (b): Determines how fast the waves oscillate. A higher value creates more frequent waves. Ability to Invert the output: Just like any cosine function it starts its journey with a decline, which is not distinctive to the behavior of most assets. The default setting is in "inverted mode". Scale Factor: Adjusts the speed at which the oscillations grow over time. Number of Terms (n_terms): Increases the number of waves. More terms add complexity to the pattern.

Vector ScalerVector Scaler is like Stochastic but it uses a different method to scale the input. The method is very similar to vector normalization but instead of keeping the "vector" we just sum the three points and average them. The blue line is the signal line and the orange line is the smoothed signal line. I have added the "J" line from the KDJ indicator to help spot divergences. Differential mode uses the delta of the input for the calculations. Here are some pictures to help illustrate how this works relative to other popular indicators. Vector Scaler vs Stochastic Vector Scaler vs Smooth Stochastic RSI average set to 100 average set to 200

Reverse Ehler Instantaneous Trendline - TraderHalaiThis script uses a reverse function of the famous Ehler Instantaneous Trendline to calculate the source price required in order to change from Bullish to bearish From my analysis, the reverse price does appear to be rather choppy, though it is 100% accurate. This is because Ehler's Instantaneous Trendline tends to remain trending for longer periods of time with above average hold periods. The main suitability for this would be higher level timeframes, such as Weekly, 5 daily, 3 daily. From my findings Smoothed Heikin Ashi Trend, tends to provide better risk-adjusted returns across most timeframes (Higher return to drawdown ratio) As I have spent a bit of time getting the reverse function mathematics to work, I decided to publish this as open source for the benefit, scrutiny and for further development by the TradingView community anyways. Enjoy!

Vertical LinesThis script plots vertical lines on charts or indicators. Unfortunately pinescript is lacking a vertical line plotting function. Vertical lines are useful to mark events, such as crossover of levels, indicators signals or as a time marker. After searching the internet for a long time and trying different scripts, this script is the simplest and visually the best. You would think that plotting a vertical line would be relatively easy, it is not! I thank the unknow author for sharing this solution and now I will share it on tradingview to make it readily available to anybody that needs it. RSI crossover signals are used as an example in this script. When the RSI crosses over 70 or below 30, the script plots a red or green vertical line. The script plots a vertical line as a histogram bar. The histogram bar must have a height. Setting the height near infinity like 1e20 will cover all the ranges from top to bottom in most charts, but doesn't work all the time. If the chart range is small in values, the line is not plotted or the chart is visually compressed because the top of the bar is also a data point in the chart. Another solution is to find the highest point in the chart and multiply it by a number from 2 to 10 to set the top of the histogram bar. But this solution doesn't work if the line is drawn in the indicator window. additionally if the chart or indicator includes negative values, a histogram bar with a negative height must be concatenated to the histogram bar with a positive height to cover the positive and negative range. It would seem intuitive to include a vertical plot function since it is very useful and pinescript already has a horizontal line plot function called Hline. But pinescript is becoming less intuitive, and redundant. A case in point is Version 4 variable declaration and naming, it less intuitive and more redundant than previous versions. I beg Tradingview to adopt a more refined scripting language such as Matlab or Python for charting purposes. These languages can be easily ported to other analysis programs for AI or statistical analysis.

[FN] Strategy - Store Level on ConditionThis is a function that you can use in strategies. Not a strategy in and of itself. Example thumbnail is showing the function applied to a strategy. Oftentimes, I am asked a question regarding how to hold a variable at a specific, constant level over a conditional period of time. This question is always asked in a very long convoluted way like "I want the strategy to know what the high of the last pivot was while I'm in a long." or some other variation of wanting a script to remember something from prior bars. This function is designed to store a price or some numeric level on the bar that your conditional (bool) statements determine that it should be stored. In this construct, you would set conditional statement(s) to flip the 'hold condition' to be true on the next bar, then hold that value until either the "hold condition" is no longer true or the initial conditions trigger again, causing an update to the level that you want to capture. You still have to come up with the logic for the start condition and hold condition on your own, but I've provided an example that should give you an idea of how to accomplish this and customize/deploy the function for your purposes. The function will return 'na' when neither the start condition nor hold condition are true. There's multiple ways to implement this and variations on how the level is chosen. I've written extensive notes in the script to guide you through the logic behind the function. My hope is that it will be useful to those trying to build strategies or anyone attempting to get their script to remember a level under given conditions. In the thumbnail example, the take profit level is defined at the beginning of the trade and held until the take profit order executes. The order execution is a separate matter. However, storing the take-profit level at a static value is key to telling the strategy.exit() function what price to execute a limit exit order at. Example: strategy.exit("Exit Long", from_entry = "long", qty_percent = 100, limit = stored_value) Let me know how it works out for you and if I can be of any assistance. Note: Strategy results are mainly derived from the fact that the strategy is long-only, the NQ only goes up, and there is no stop loss in place. So don't ask for the specific strategy, because unless you're trading a single contract with a $500,000 account, you'll probably get liquidated using this strategy as it is presented.

Linear Regression & RSI Multi-Function Screener with Table-LabelHi fellow traders.. Happy to share a Linear Regression & RSI Multi-Function Custom Screener with Table-Labels... The Screener scans for Linear Regression 2-SD Breakouts and RSI OB/OS levels for the coded tickers and gives Summary alerts Uses Tables (dynamica resizing) for the scanner output instead of standard labels! This Screener cum indicator collection has two distinct objectives.. 1. Attempt re-entry into trending trades. 2. Attempt Counter trend trades using linear regression , RSI and Zigzag. Briefly about the Screener functions.. a. It uses TABLES as Labels a FIRST for any Screener on TV. b. Tables dynamically resize based on criteria.. c. Alerts for breakouts of the UPPER and the LOWER regression channels.(2 SD) d. In addition to LinReg it also Screens RSI for OB/OS levels so a multifunction Screener. e. Of course has the standard summary Alerts and programmable format for Custom functions. f. Uses only the inbuilt Auto Fib and Lin Reg code for the screener.(No proprietary stuff) g. The auto Zigzag code is derived(Auto fib). Question what are all these doing in a single screener ?? ZigZag is very useful in determining Trend Up or Down from one Pivot to another. So Once you have a firm view of the Current Trend for your chosen timeframe and ticker… We can consider few possible trading scenarios.. a. Re-entry in an Up Trend - Combination of OS Rsi And a Lower Channel breach followed by a re-entry back into the regression channel CAN be used as an effective re-entry. b. Similarily one can join a Down Trend on OB Rsi and Upper Channel line breach followed by re-entry into the regression channel. If ZigZag signals a range-bound market, bound within channel lines then the Upper breakout can be used to Sell and vice-versa! In short many possibilities for using these functions together with Scanner and Alerts. This facilitates timely PROFITABLE Trending and Counter trend opportunities across multiple tickers. You must give a thorough READ to the various available tutorials on ZigZag / Regression and Fib retracements before attempting counter trend trades using these tools!! A small TIP – Markets are sideways or consolidating 70% of the time!! Acknowledgements: - Thanks a lot DGTRD for the Auto ZigZag code and also for the eagerness to help wherever possible..Respect!! Disclaimer: The Alerts and Screener are just few tools among many and not any kind of Buy/Sell recommendations. Unless you have sufficient trading experience please consult a Financial advisor before investing real money. *The alerts are set for crossovers however for viewing tickers trading above or below the channel use code in line 343 and 344 after setting up the Alerts! ** RSI alerts are disabled by default to avoid clutter, but if needed one can activate code lines 441,442,444 and 445 Wish you all, Happy Profitable Trading!
