Overview
FX Blue's Trader Sentiment aggregates the open positions of all real-money accounts which are currently publishing their results to FX Blue. It is based on the net position of each user. For example, if a trader is running a grid system which currently has 20 orders open on each side, then the figures include one single net figure for that user, not 40 separate positions.
History
The Trader Sentiment indicator for MT4 shows a minute-by-minute history for the symbol over the last 2 trading hours. Positions can change very rapidly in reaction both to news and price movements. A news event which does not cause a major movement in the symbol's price can nevertheless lead to a big change in the number of people long/short. It is not uncommon for the number of users long/short EURUSD to change by as much as 30 percentage points (e.g. from 35%/65% to 65%/35%) very quickly in reaction to a major news event.
