Demand And Supply Diagram MT4

The balance of supply and demand is a simple and effective market analysis method.

The supply and demand diagram can show you in advance, even before the trend reversal, where the supply ends and the demand is already emerging, where the demand ends and the supply is emerging, while substantially increasing the probability of a deal.


Indicator Signals

The indicator generates four main signals:

  • ND - no demand.
  • NS – no supply.
  • ED – excess demand (the culmination of supply according to VSA theory).
  • ES – excess supply (the culmination of demand according to VSA theory).

The indicator also remembers and analyzes the sequence of these signals, determines optimal areas for entering the market and shows an additional text message "buy area" or "sell area". It is recommended to make a final entry decision based on signals from at least two timeframes, including the current and a higher one.

The indicator builds a supply and demand diagram for each chart period.

On the M1 period it is a chart for the last 15 minutes (15 candlesticks), for M5 it is the last hour (12 candlesticks), for M15 it is the last four hours (16 candlesticks), for M30 it is the last eight hours (16 candlesticks), for H1 - the last day (24 candlesticks), for H4 - the last week (30 candlesticks), for D1 - for the last month (22 candlesticks), for W1 - the last quarter (13 candlesticks), MN - the last year (12 candlesticks).

The TfShift variable shifts the applied period, so that the diagram becomes more extended and detailed.

On the M1 period it is a chart for the last hour (60 candlesticks), for M5 it is the last 4 hours (48 candlesticks), for M15 it is the last 8 hours (32 candlesticks), for M30 it is the last day (48 candlesticks), for H1 - the last week (120 candlesticks), for H4 - the last month (132 candlesticks), for D1 - for the last quarter (66 candlesticks), for W1 - the last year (52 candlesticks), MN - the diagram will not be drawn.
