# Signaplex

> Signaplex publishes the Power Slope Index (PSI), a trend indicator that reads five nested market frames — POWER, SPEED, LIFT, PITCH and SLOPE — and condenses them into one PSI Composite score from −100 to +100. Positive values indicate an uptrend, negative values a downtrend; the larger the magnitude, the more established the trend.
