Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
NIG Probability Table measures mean, standard deviation, skewness, and kurtosis over a rolling window, then sets the bin range with an ATR multiple. On the last bar it draws colored boxes in a separate pane, optionally labeled with each bin probability. Window length, ATR length and multiplier, bin count, and box width are adjustable. It does not generate trade signals.
The inputs you can change from the gear icon on the chart. Defaults are the author's.

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.

This indicator scans a pasted list of symbols and shows matching long and short setups in a table in a separate pane. It uses a Supertrend crossover, then applies an ATR or fixed-point volatility range so quiet, sideways conditions can be skipped. Optional fil
This statistical analysis tool mines historical relationships between RSI values and candle volatility. It calculates a 14-period RSI from the previous bar and normalizes absolute price change using a 14-period Average True Range (ATR). Based on the normalized
Market Speedometer plots a 0-100 market speed reading in a separate pane. It measures movement by bar-to-bar change, true range, or a short average of recent bars, then ranks that movement against ATR and a percentile lookback. An EMA smooths the reading, and
The 8-Factor Composite Screener evaluates equities across fundamental and technical criteria, including valuation ratios, earnings and revenue growth, 12-month return momentum, proximity to 52-week highs, Stage 2 moving average alignment, benchmark relative st
This indicator summarizes higher-timeframe candle range statistics by time of day and shows them in a table in a separate pane. It groups candles into slots for 5-minute, 15-minute, 1-hour, 4-hour, 8-hour, or 12-hour periods over a chosen lookback in days, and
This indicator transforms standard RSI calculations into logit space, estimating rolling distributions to derive empirical z-scores mapped back to the 0–100 RSI scale. Plotted in a separate pane, it features multi-horizon central lines—fast and structural cent
