What is this indicator?
Zones on a chart where a large volume of institutional orders were placed just before a big price move. Price returning to these zones is often met with a strong reaction, especially when confirmed by trading volume.
How to read the chart
A pattern forming completely and getting confirmed by volume or the next candle raises the signal's validity; an incomplete or unconfirmed pattern can produce the opposite result.
Practical tip
A pattern's validity increases on higher timeframes and with heavier trading volume; on very low timeframes there's a lot of noise.
