Hello, thanks for your message. It does not work based on the support / resistance principle. Sometimes the indicator shows the buyers / sellers zones that are similar to the S/R zones, but it is not always the same. The reason why there are currently no buyers zones on EUR/USD is that there is a strong downside move on EUR/USD making new lows. The indicator works based on statistics and probability, so the indicator will wait until the market moves will be stabilized and draw the buyers zones then. Also, you are able to change the sensibility of the zones by changing the "Buyers & Sellers factor" in the indicator's settings. Anyway, I will be more than happy to collect all feedback and improve next versions of the indicator.
