DollarIndex is an indicator that computes the volume-adjusted flow of USD considering all 7 major currency pairs. When reading the indicator, remember that values above the 0.0 line are net flows positive for USD. If you are viewing a pair in which USD is the 2nd currency, for example EUR/USD, positive net flows of USD (an "above-the-line" indicator reading) will *generally* show negative (short, bearish) price-action, and similarly vice-versa, negative net flows of USD will show positive (long, bullish) price-action. When USD is the first currency, e.g. USD/JPY, flows will *generally* align with price action.
