FVG, Order Blocks and Breakers
From the same chapter
- PD ArrayAny zone where the algorithm delivers price: FVG, Order Block, Breaker, Mitigation Block…
- FVGA three-candle gap where price moved so fast it went untraded. It tends to rebalance.
- BISIA bullish FVG: the gap sits below and acts as support on the return.
- SIBIA bearish FVG: the gap sits above and acts as resistance on the return.
- CEThe 50% of an FVG. The most reliable reaction level inside the gap, and where the order goes.
- Order BlockThe last opposing candle before the displacement that breaks structure. When price returns, the same actor defends it.
- BreakerAn Order Block that failed and was broken: on the return it acts in the opposite direction to the original.
- Mitigation BlockA zone price returns to so a trapped institutional position can exit at a better price. Like a breaker but without a prior liquidity sweep; in ICT's original usage it tends to be traded as continuation, not reversal.
