The Positive Volume Index tracks price changes exclusively on days when volume increases, reflecting crowd-driven activity and retail sentiment. PVI works in tandem with the NVI to contrast smart-money behaviour with public participation in stock and crypto markets. Explore our indicator guide library for the full suite of volume-based analytical tools.
When today's volume exceeds yesterday's: PVI = previous PVI + (percentage price change × previous PVI). When volume decreases, PVI stays unchanged. A 255-day EMA is used as a signal line. PVI rising on high volume reflects crowd enthusiasm and retail participation.
Ease of Movement relates price change to volume, showing how easily price is moving — large price change on low volume produces high EMV readings, while small moves on heavy volume produce low readings. It is a unique perspective on market efficiency useful in <a href="/market/stocks" class="text-primary hover:underline">stocks</a> and <a href="/market/forex" class="text-primary hover:underline">forex</a>. Add EMV to your <a href="/strategies" class="text-primary hover:underline">trading strategies</a> alongside other volume tools from our <a href="/academy/indicators" class="text-primary hover:underline">indicator guide library</a>.
