What does Positive volume index measure?
A line that only moves on BUSIER days — the days traditionally credited to the crowd rather than to well-informed money.
How is Positive volume index calculated?
Start at 1000. On any candle whose volume was HIGHER than the previous candle's, move the line by that candle's percentage price change. On quieter candles, leave it alone.
Written by reading the engine’s real computation, not a textbook — where the two differ, the page describes what actually runs.
How do I use Positive volume index in a bot?
In the builder, add an indicator of type pvi. Its value becomes an operand you can compare in any entry or exit rule. The engine grades the whole rule honestly: real fills, no look-ahead, half the history held back.
