CAHOLD / CBLOHD

CAHOLD (Close Above Highest Low Day) and CBLOHD (Close Below Lowest High Day)

The logic is based on identifying pullbacks followed by strength in the direction of the trend, making it useful as a trend-continuation entry signal rather than a reversal tool.

⸻

How CAHOLD Works (Bullish)
    1.    A sequence of red candles forms (a pullback).
    2.    The first green candle appears.
    3.    The script identifies the highest high of the prior red-candle sequence (HOLD).
    4.    A CAHOLD signal triggers when a green candle closes above that HOLD level.
    5.    A small green arrow is plotted below the candle.

⸻

How CBLOHD Works (Bearish)
    1.    A sequence of green candles forms (a bounce).
    2.    The first red candle appears.
    3.    The script identifies the lowest low of the prior green-candle sequence (LOHD).
    4.    A CBLOHD signal triggers when a red candle closes below that LOHD level.
    5.    A small red arrow is plotted above the candle.
