The 1 min is pretty responsive although not always: The current high was at 2727, Kagi turned red at 2725 and here we are currently at 2717.... But one needs a little experience to get to know it. I like to use them with BBs...
Did some good scalps today, maybe one day I will be able to make a longer term trade, but price moves too fast today to post any of my trades on a shorter term time chart.
