This indicator marks Break of Structure (BoS) and Change of Character (ChoCh) in the price structure on your charts. It runs on any timeframe. This indicator is useful for determining if you are seeing a trend change in the market or if you are only seeing a pullback with the market continuing in the direction of the trend. The indicator will look for price to break the previous BoS line or ChoCh line to mark a new BoS. When a BoS line is broken, it will then look for the lowest or highest pullback (depending on which way the market is trending) between to 2 BoS lines to mark the ChoCh line. When the ChoCh line is broken, it will mark that line as BoS and the previous BoS line will become ChoCh.
What makes this indicator unique from other BoS and ChoCh indicators is that it follows specific rules used by the FTR Trading group. The main difference is that the ChoCh line isn't changed to a BoS line from only a candle wick break. You will need a candle body break to move your BoS line to ChoCh. If a candle wick breaks your ChoCh line, you simply extend the ChoCh line to the new high or low of the wick. There are smaller differences that are proprietary to the FTR strategy.
