The Key Candle Tool Kit merges four institutional-concept engines - High Probability Order Blocks, Key Liquidity Levels, Balanced Price Range, and CISD Levels - into a single indicator, then layers cross-module confluence logic on top that none of the components can produce alone. Instead of cross-referencing four studies to judge whether a zone matters, the Kit does the cross-referencing internally and marks the zones and levels where structure actually stacks.
