Uptrend: Candle closed higher than highest close
Downtrend: Candle closed lower than lowest close
This works best on higher time frames since a daily close is more powerful than a 15 minute close.
A few examples how you could use this:
Use support & resistance
Apply a moving average
Buy and sell the break-out
