Sentiment Analysis
Measuring how market participants are positioned and how bullish or bearish they are, often used as a contrarian filter.
What Sentiment Analysis means
Sentiment analysis attempts to measure how market participants are positioned and how bullish or bearish they feel, on the view that crowded positioning is itself a source of risk. Typical inputs include the weekly Commitment of Traders report on futures positioning, retail client-position statistics published by brokers, option risk reversals and implied volatility, fund flow data and investor surveys. Some modern feeds are assembled automatically from news wires and social media text. The output is a reading of how one-sided a market has become rather than a direct price forecast.
Sentiment is most often used as a contrarian filter at extremes: when almost every speculator is already long a currency, the marginal buyer needed to push it higher is scarce, and a modest disappointment can trigger an outsized unwind. Used on its own it is a weak timing tool, because extremes can persist and deepen for months while price keeps trending. Positioning data is also lagged and partial, and statistics from one broker describe only that broker's client base rather than the wider market.
Worked example
If a broker reports 78% of its clients holding long GBP/USD near 1.2700 while futures speculators also carry a large net long, a contrarian reads the market as crowded and demands stronger evidence before adding to the long side.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
