This might seem confusing at first to have the 100 % level at the start of the move, but it makes perfect sense if you think about it like this: You are looking for a retracement of a move, so by the time the move is finished and the market starts retracing, it is moving back toward the origin of the move and if it were to retrace back up or down on the whole move, it would then have retraced 100% of the move. When you have a price action signal present on the daily chart, you then match up the fib 50% retracement level if there is one present (see chart example below), if the price action candlestick signal matches up with the 50% swing retracement level then you’re good to go and potentially have a valid trade.
