here I will explain with the help of chart see below, how both BB and price action come to the same conclusion, one by calculation the other by eyeballing the market;the market is the same!
in the chart the market goes below the BB at the red arrow marked 1;this is a BB continuation signal.
it then retraces to the moving average,and then continues to the lower band BUT DOES NOT GO OUTSIDE OF IT.
BB is showing that the move down from the average is less volatile than the previous move down,which broke the lower BB: this is is a BB BUY SIGNAL.
PRICE ACTION traders will notice that the move sown from the average was much slower than the previous move down, that market took 7 bars to go down while in the previous move down,it took only 2 bars,made two attempts to break the previous low, failed and then went up,this is a failed low2, which is a High2, so this is a price action buy signal.
two different ways to reach the same destination.View attachment 185894
