Supply & Demand is one of the core strategies used in trading. It focusses on the ancient laws of supply and demand
and how price moves in a free-flowing market. The foundation of this strategy is that the amount an instrument thats available and the desire of buyers for it, drive the price. It identifies zones on the chart where demand overwhelms supply (the demand zone), driving the price up or where supply overwhelms demand (the supply zone), driving the price down. Most supply and demand traders wait for the price to enter these zones, where major activities of buying or selling have taken place, before entering a long or short position themselves.
Fresh zones are more effective than retested zones. They can be used as entry zones for a continuing trend or as reversal zones for a changing trend because it makes sense to buy in a demand zone and to sell in a supply zone. Both of these trades can be made aggressively or conservatively and they all have their own rules to enter or exit trades. TradingView has a smart drawing tool
that allows users to visually identify these levels on a chart.
