When analysing Fair Value Gaps (FVG) or Order Blocks (OB) in smaller time frames, several key factors must be considered to enhance trading accuracy:

Context & Higher Time Frame Alignment – Smaller time frame FVGs or OBs are more reliable when they align with higher time frame structure (e.g., daily/weekly levels). A 5-minute FVG near a daily OB carries more weight.

Liquidity & Volume – Check if the FVG/OB forms near key liquidity zones (high-volume nodes, swing highs/lows). Thin liquidity can lead to false breaks.

Momentum Confirmation – Use price action (e.g., strong rejection, engulfing candles) or indicators (RSI, MACD) to confirm reactions at these levels.

Size & Quality – Larger, cleaner FVGs (3+ candle gaps) or fresh OBs (untested) have higher validity. Small, fragmented gaps may lack significance.

Market Phase – FVGs work best in trending markets (retracement fills), while OBs excel in reversal/consolidation zones.

Time Sensitivity – Smaller time frames decay faster; avoid over-trading minor gaps unless part of a larger pattern.

By combining these factors, traders can filter high-probability setups while avoiding noise. Always prioritise confluence with market structure.
