For the more expert scripters, I define these price zones as:
Supply = The most recent price high before the price swing to a new low and the open of the last bullish candle before the price drop.
Demand = The most recent price low before the price advance and the open of the last bearish candle before the price rose.
Do you concur OGK?
The script about for Mobius supply and demand is decent but it ridget, I have not tested it on smaller time frames but on larger time frame it's decent but doesn't adjust if the price dips below or above to find new areas.
