DESCRIPTION
A Gatekeeper node is a commonly seen heatmap setup where a high-value node sits between price and further high-value nodes, preventing continuation. This node then serves as a key support or resistance level.HOW TO APPROACH
Many traders mark gatekeeper strikes on the chart, because price often stalls or reverses as it approaches them. A reversal at the gatekeeper is more likely to hold when the Gatekeeper node’s value is far larger than the nodes beyond it. As always, price action and market structure matter as much as the map.- Example 1
