High Probability Order Blocks & Fair Value Gaps

High Probability Order Blocks & Fair Value Gaps is a free TradingView overlay indicator developed by NAMI Trading. It automatically detects and displays order blocks and fair value gaps on your chart with real-time mitigation tracking — giving you a clear view of where institutional liquidity was created and where price is likely to react next.

This is the lite edition of our premium SMC PRO indicator. It provides the core order block and FVG detection engine with full visual customization, making it an ideal entry point for traders learning Smart Money Concepts or anyone who wants clean institutional structure on their charts without a subscription.

How to Use High Probability Order Blocks & Fair Value Gaps

After adding the indicator to your TradingView chart, order blocks and fair value gaps immediately begin rendering on your active timeframe. No configuration is required to get started — it works out of the box.

Order blocks appear as colored zones on your chart: bullish OBs (green) form when a down candle is followed by an up candle that closes above the prior high, indicating institutional buying. Bearish OBs (red) form in the opposite scenario — institutional selling. When price returns to an order block and touches it, the zone recolors to a mitigated state, signaling that the liquidity has been absorbed.

Fair value gaps are untraded price zones where candles skip over price without filling. These imbalances act as magnets — price often returns to fill them. The indicator renders FVGs as bordered zones and tracks their mitigation status in real-time.

Common setups include:

• Identifying bullish order blocks at support for long entries
• Watching bearish order blocks at resistance for short setups
• Trading FVG fills as mean-reversion plays
• Combining OB + FVG confluence for higher-probability entries
• Using mitigated vs. unmitigated zones to filter live vs. dead levels

Key Features

Order Block Detection

Automatically identifies high-probability bullish and bearish order blocks based on institutional candle patterns. Each block renders as a color-coded zone with customizable borders and labels.

Fair Value Gap Detection

Scans for bullish and bearish fair value gaps — untraded price zones where candles jumped over price. FVGs are rendered as bordered zones that extend forward until price interacts with them.

Real-Time Mitigation Tracking

When price touches an order block or fair value gap, the zone automatically recolors to a mitigated state and stops extending. This lets you instantly see which levels are still active and which have been absorbed.

Full Visual Customization

Every color, border style, transparency, text size, and label color is fully configurable. Match the indicator to your chart theme and personal visual preferences.

Lightweight & Free

No subscription, no fees, no account required beyond TradingView. Add it to your chart and start identifying institutional structure immediately.

Use Cases

Order Block Bounce Entries

Identify unmitigated bullish order blocks near support. When price pulls back into the OB zone and holds, enter long with your stop below the block. The zone represents where institutional buyers stepped in — if it holds, price is likely to push higher.

FVG Fill Trading

Fair value gaps are imbalances that price tends to fill. When you spot an unfilled FVG, anticipate price returning to that zone. Enter on the fill and target the opposite side of the gap for a clean mean-reversion trade.

OB + FVG Confluence

The highest-probability setups occur when an order block aligns with a fair value gap. When both zones overlap at the same price level, institutional liquidity and market imbalance converge — creating a strong reaction zone.

Frequently Asked Questions

Is this indicator free?

Yes — completely free, no subscription, no account required beyond TradingView. Add it to any chart and start using it immediately.

What's the difference between this and NAMI SMC PRO?

This is the lite edition. It provides core order block and FVG detection with mitigation tracking. SMC PRO adds volumetric data (real dollar volume and contract counts on every block), breaker block detection, up to 100 OBs/FVGs simultaneously, and unlimited lookback depth. If you outgrow the free version, SMC PRO is the natural upgrade.

What TradingView plan do I need?

This indicator works on all TradingView plans, including the free tier.

Does it work with other NAMI indicators?

Yes. Pair it with the free Custom Message Rotator for on-chart notes, or upgrade to the full NAMI suite for momentum confirmation (NAMI 2.0), trend analysis (ENIGMA, TRAVIS), and ICT entry strategies (NAMI SMB).

Does it repaint?

Order blocks and FVGs are printed on confirmed candle patterns and do not repaint once plotted. Mitigation recoloring updates in real-time as price interacts with zones.
