The Supply and Demand Zones is one of my favs BUT getting a signal WHEN IT ENTERS A ZONE is only useful for an alert if you need to exit as that zone was your target. As at most times it can be in that zone for many many hours ,days consolidating for liquidity purposes.

I needed to know when it leaves a Zone as a kind of retesting of the zone or simply it's first exit out of the zone so i could begin trading in the direction of the exit.

So here is my amended version indicator of the original to tell me that the candle is leaving the zone. Remember the greater the fuzzy the more likely it is to constantly enter and exit that zone
