**Order Block**:
An order block is a specific price area on a financial chart where institutional traders have placed large buy or sell orders. These areas often lead to significant price movements and are used by traders to identify potential zones of support or resistance. Order blocks represent clusters of orders from big players like banks or hedge funds, signaling where major buying or selling interest lies. When price revisits these zones, it often reacts strongly, making them valuable for predicting price reversals or continuations.
**Fair Value Gap**:
A fair value gap (FVG) is a price range on a chart where there is an imbalance between buyers and sellers, often created during periods of high volatility or news events. This gap typically occurs when the market moves so quickly that trades do not fully fill, leaving a visible gap on the chart. Traders use fair value gaps to anticipate potential price retracements to these levels, as the market tends to revisit and fill these gaps over time, aligning price with its perceived fair value.
Both concepts are crucial in technical analysis for identifying key price levels where significant market activity is likely to occur.
