Support & Resistance

Support and resistance indicators identify key price levels where buying or selling pressure is likely to appear. This category includes both classical techniques (Fibonacci, Golden Zone) and Smart Money Concepts (SMC) / ICT methods (Order Blocks, Liquidity Sweeps, etc.). Most of these are real-time — they react to structural price action rather than smoothing history — though they often have a confirmation delay while waiting for swing points to be validated.

Detailed descriptions

Fibonacci Retracement

🟢 Real-time

Warmup: 2 bars (default: 2 bars)

Compute static retracement levels (23.6%, 38.2%, 50%, 61.8%, 78.6%) between a swing high and low. Use it to identify potential support/resistance zones during pullbacks in a trending market.

Golden Zone

🔴 Lagging — ≈ length / 2 bars

Warmup: length bars (default: 60 bars (length=60))

Highlights the 61.8%-78.6% Fibonacci zone — the strongest retracement area. Use it as a high-probability entry zone during pullbacks.

Golden Zone Signal

🟢 Real-time

Warmup: Same as Golden Zone (length bars) (default: 60 bars (length=60))

Generates buy/sell signals when price enters or exits the Golden Zone. Use it as a trigger alongside the Golden Zone overlay for systematic entries.

Fair Value Gap (FVG)

🟢 Real-time

Warmup: 3 bars (default: 3 bars)

Detects 3-candle imbalance patterns where institutional order flow left a gap. Use FVGs as high-probability zones where price tends to return to rebalance.

Order Blocks

🟢 Real-time — ≈ swing_length bars after the pivot

Warmup: 2 × swing_length + 1 bars (default: 21 bars (swing_length=10))

Identifies the last opposing candle before a strong move — the footprint of institutional orders. Use order blocks as support/resistance zones for entries with tight stops.

Breaker Blocks

🟢 Real-time — ≈ swing_length bars after the pivot

Warmup: 2 × swing_length + 1 bars (default: 11 bars (swing_length=5))

Former order blocks that have been broken and flipped. When bulls fail, their order block becomes bearish resistance (and vice versa). Use them for continuation entries after a market-structure shift.

Mitigation Blocks

🟢 Real-time — ≈ swing_length bars after the pivot

Warmup: 2 × swing_length + 1 bars (default: 11 bars (swing_length=5))

The first same-direction candle in an impulse leg leading to a market-structure shift. Use them as precision entry zones — tighter than order blocks but with a higher hit rate.

Rejection Blocks

🟢 Real-time — ≈ swing_length bars after the pivot

Warmup: 2 × swing_length + 1 bars (default: 11 bars (swing_length=5))

Candles with large wicks at confirmed swing points, showing price rejection. Use them to identify levels where price was strongly pushed back and may react again.

Optimal Trade Entry (OTE)

🟢 Real-time — ≈ swing_length bars after the pivot

Warmup: 2 × swing_length + 1 bars (default: 11 bars (swing_length=5))

Fibonacci retracement of an impulse leg after a market-structure shift. Use OTE to time entries at the best risk/reward zone within a confirmed move.

Market Structure Break

🟢 Real-time — ≈ pivot_length bars after the pivot

Warmup: 2 × pivot_length + 1 bars (default: 15 bars (pivot_length=7))

Detects when price breaks a confirmed pivot high/low with momentum. Use it to identify trend changes and potential reversal points.

Market Structure CHoCH/BOS

🟢 Real-time — ≈ length bars after the fractal

Warmup: 2 × length + 1 bars (default: 11 bars (length=5))

Distinguishes between Change of Character (CHoCH) and Break of Structure (BOS). CHoCH signals a potential reversal; BOS confirms trend continuation. Essential for SMC/ICT trading.

Liquidity Sweeps

🟢 Real-time — ≈ swing_length bars after the swing

Warmup: 2 × swing_length + 1 bars (default: 11 bars (swing_length=5))

Detects when price wicks through a swing point and reverses — a classic liquidity grab. Use it to spot institutional stop hunts and trade the reversal.

Buyside & Sellside Liquidity

🟢 Real-time — ≈ detection_length bars after the pivot

Warmup: 2 × detection_length + 1 bars (default: 15 bars (detection_length=7))

Maps clusters of resting liquidity above highs (buyside) and below lows (sellside). Use it to anticipate where price is likely to be drawn toward next.

Pure Price Action Liquidity Sweeps

🟢 Real-time — depth-dependent

Warmup: depth-dependent (varies by fractal depth) (default: Varies — deeper fractals need more bars)

A multi-depth fractal approach to liquidity sweep detection. Use it when you want to detect sweeps across different structural depths.

Liquidity Pools

🟢 Real-time — depends on contact_count + gap_bars

Warmup: ≥ contact_count × gap_bars bars (default: Varies (contact_count=2))

Zones where price wicks have touched multiple times, indicating resting orders. Use them to identify high-probability reversal or acceleration zones.

Liquidity Levels / Voids (VP)

🟢 Real-time — ≈ detection_length bars

Warmup: detection_length bars (default: Depends on detection_length)

Highlights volume-profile voids — price areas with little trading activity. Price tends to move quickly through voids. Use them to spot potential fast-move zones.

Internal & External Liquidity Zones

🟢 Real-time — ≈ external_pivot_length bars

Warmup: 2 × external_pivot_length + 1 bars (default: 21 bars (external_pivot_length=10))

Distinguishes between internal (range-bound) and external (breakout) liquidity. Use it to understand whether price is targeting internal or external levels.

Premium / Discount Zones

🟢 Real-time — ≈ swing_length bars after the swing

Warmup: 2 × swing_length + 1 bars (default: 21 bars (swing_length=10))

Divides the current range into premium (upper) and discount (lower) zones. Buy in discount, sell in premium — the core SMC/ICT framework for directional bias.
