Smart Money structure: BOS, CHoCH, FVG, order blocks and liquidity sweeps

A rules-first explanation of common Smart Money Concepts and how HyperFX validates them with closed candles, freshness and risk.

Direct answer

SMC labels are descriptions of price structure, not proof of institutional activity. Define swing points first; then BOS/CHoCH, imbalance, order blocks and sweeps can organize evidence, but only a nearby invalidation and honest target make a scenario tradable.

What to remember

  • Structure starts with objective pivots.
  • BOS continues; CHoCH warns of transition.
  • FVG and order blocks decay with age and mitigation.
  • A sweep needs reclaim/confirmation.

BOS and CHoCH need fixed pivots

A break of structure closes beyond a meaningful prior pivot in the trend direction. A change of character breaks the opposing sequence and warns that regime may be changing. Wick-only touches and micro-pivots should not be promoted after the fact to make a narrative fit.

Practical workflow: freeze pivots and zones before price reaches them, wait for a closed-candle confirmation and record the exact condition that invalidates the scenario. This prevents hindsight relabelling.

FVG and order blocks are zones, not exact prices

A fair value gap is a three-candle imbalance; an order block is commonly the final opposing candle before displacement. Mark the full zone, age, fill ratio, invalidation and retest. Repeated mitigation weakens relevance, and a zone in the middle of a range has poor location.

Practical workflow: freeze pivots and zones before price reaches them, wait for a closed-candle confirmation and record the exact condition that invalidates the scenario. This prevents hindsight relabelling.

Sweeps, confirmation and risk

Equal highs/lows can attract orders, but a sweep is not automatically a reversal. Require a breach, reclaim or displacement, structure confirmation and a stop beyond the invalidation. If the next genuine target cannot provide at least the required R:R, the professional result is no trade.
