This script is designed for traders who want help defining their session bias it is for people who trade in sessions which will most likely be 1 4h candle. The way I trade using Price action to get my daily bias, to either look for sells or buys or both I look at the previous daily candle close and previous 4hr candle close before analyzing the structure on the lower time frames to get my session bias of bullish/bearish. so this indicator compares the daily and 4hr candles to develop a bias for example
previous daily bullish + Previous 4hr Bullish = BULLISH BIAS
previous daily Bearish + Previous 4hr Bearish = BEARISH BIAS
if Daily bullish 4hr bearish = MIXED SESSION
if daily bearish 4hr bullish = MIXED SESSION
MIXED SESSION = Can argue both buys and sells
BEARISH SESSION = Best to look for Sells only based on my trading style
BULLISH SESSION = Best to look for Buys only based on my trading style
