F = Failed cycle; a move below the previous cycle low
Swing low = a move above the candle that marks the low
Swing high = a move below the candle that marks the high
S = Stealthy cycle low, i.e. all cycles parameters were not fullfilled for a cycle low to be confirmed, but price action and time gives that it is a cycle low
