HTF Trend Filter

Trend filter based on higher timeframe candles. Can be used as entry filters.

Checks if last 3 higher timeframe candles are in fully ascending order or fully descending order. Additionally you can also check if close price is above min of last two highs or below max of last two lows.

Lime and Orange candles imply partial trend in higher timeframe. (only last 3 candles align)
Green and Red candles imply complete trend. (last 3 candles align along with current close price).

Just an experiment. Can be further improved,
