This indicator plots several linear regression channels on the price chart. Each channel can be hidden or drawn as a channel, bands, or both, and its lookback is anchored to price, volume, oscillator extremes, calendar periods, sessions, or corporate events. P

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
42H Map partitions market action into forty-two-hour cycles, ten-and-a-half-hour micro-sessions, half-week periods, and quarter-month segments to track highs, lows, and midpoint levels. The script evaluates trap conditions and potential stop levels around cycle midpoints using ATR buffers. User inputs allow enabling a daily EMA trend filter, adjusting the daily EMA length, and calibrating ATR multipliers for neutral noise bands and stop-loss buffers. Note that cycle tracking relies on a fixed time anchor rather than exchange session schedules.

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
