🔥 Trendline Breakout 5-15-1hr-4hrs-DAY-WEEK (HTF)

//The percentLen (length for HH/LL calculation) defines how many candles (bars) to look back when calculating the highest high (HH) and lowest low (LL) values on the selected timeframe (percentTF).
//How It Works:
//ta.highest(high, percentLen)
//Finds the highest price in the last percentLen candles on the selected timeframe.
//Example: If percentLen = 20, it finds the highest high of the last 20 candles.
//ta.lowest(low, percentLen)
//Finds the lowest price in the last percentLen candles on the selected timeframe.
//For previous HH/LL (hh_prev and ll_prev), the script calculates the HH/LL from the period before the current percentLen bars, using:
//pine
//Copy
//Edit
//ta.highest(high, percentLen * 2)[percentLen]
//This shifts the window back by percentLen bars to get the previous range.
//Why Is It Needed?
//The script calculates % change between the current HH/LL and the previous HH/LL:
//pine
//Copy
//Edit
//hh_change = ((hh_now - hh_prev) / hh_prev) * 100
//ll_change = ((ll_now - ll_prev) / ll_prev) * 100
//This shows how much the market's extremes (highest highs & lowest lows) have shifted compared to the last segment.
//Example:
//Timeframe (percentTF) = 1 Day
//Length (percentLen) = 20
//This means:
//hh_now = highest high of the last 20 days.
//hh_prev = highest high of the 20 days before that.
//The % change tells you if the current 20-day range’s top is higher/lower than the previous 20-day range’s top.
