Trending Bull Entry Timing

When This Skill Activates

Apply this skill when all three core conditions are simultaneously true:

1. Trend confirmation: Price is making higher highs and higher lows on the 1h timeframe over the prior 12+ candles
2. OI trend alignment: Open interest is rising alongside price (smart money adding to longs, not short-covering driving the move)
3. Funding is sustainable: 1h funding rate is < 0.03% (carry cost does not structurally erode the trade — see high-funding-carry-avoidance)

Also apply when transitioning out of a post-cascade re-entry (see liquidation-cascade-risk) where OI has flushed and price structure is rebuilding — these are the highest-probability trending bull setups.

Core Principle

In a trending bull regime, the primary edge is buying pullbacks to structural support, not chasing breakouts. Price in a trend oscillates between expansion (breakout legs) and contraction (retracement to support). The highest reward-to-risk entries occur during contraction phases — when sentiment is briefly bearish and weak hands are shaken out — not at the moment of maximum bullish conviction.

Rule: Enter at structure, not at momentum. The worst time to enter a trending market is when it feels the most bullish.

Trend Regime Classification

Before sizing or timing any entry, classify the current trend regime:

Regime	Criteria	Entry Approach
Nascent trend	< 3 HH/HL sequences; OI just turning up; funding neutral	Small initial size (0.4×); requires confirmation candle
Established trend	3–8 HH/HL sequences; OI steadily rising; funding < 0.02%/h	Standard size (0.8–1.0×); pullback entries preferred
Mature trend	8+ HH/HL sequences; OI at 30d high; funding 0.02–0.03%/h	Reduced size (0.5×); tighter stops; proximity to exhaustion
Exhausted trend	OI plateauing or declining vs. prior high; funding > 0.03%/h	No new longs; manage existing; watch for reversal

Reclassify regime every 4h or after any candle that closes below the prior swing low — a lower low invalidates the HH/HL structure regardless of other indicators.

Entry Timing Framework

Step 1 — Identify the Trend Anchor Levels

For each trending asset, maintain three dynamic levels updated after every new swing high confirmation:

swing_high_current   = most recent confirmed HH (candle with lower highs on both sides)
swing_low_prior      = most recent confirmed HL (the last pullback low)
trend_leg_size       = swing_high_current - swing_low_prior

# Fibonacci retracement targets for pullback entries:
fib_382 = swing_high_current - (trend_leg_size * 0.382)   # shallow pullback
fib_500 = swing_high_current - (trend_leg_size * 0.500)   # mid pullback
fib_618 = swing_high_current - (trend_leg_size * 0.618)   # deep pullback
fib_786 = swing_high_current - (trend_leg_size * 0.786)   # maximum pullback

# Invalidation level (stop reference):
trend_invalidation   = swing_low_prior - (trend_leg_size * 0.05)  # 5% below prior HL

Step 2 — Classify Pullback Depth

Pullback Depth	Fib Level	Signal Quality	Size Multiplier
< 23.6% retracement	Above fib_236	Weak — trend may be exhausting (no new ATH imminent)	0.3×
23.6–38.2%	fib_236 to fib_382	Moderate — strong trend, shallow pullback	0.6×
38.2–50.0%	fib_382 to fib_500	Optimal — healthy correction, high continuation probability	1.0×
50.0–61.8%	fib_500 to fib_618	Good — deeper correction, still valid in established trend	0.9×
61.8–78.6%	fib_618 to fib_786	Caution — near structural limit; require volume confirmation	0.5×
> 78.6% retracement	Below fib_786	Trend likely broken — apply invalidation protocol	0×

Step 3 — Entry Confirmation Trigger

Never enter purely on price reaching a Fibonacci level. Require one confirmation signal from the following, observed on the 15m or 1h chart at the retracement level:

• Bullish engulfing candle: current candle body fully engulfs the prior bearish candle body at or near the fib level
• Volume spike on bounce: volume on the bounce candle is > 1.5× the 20-candle average volume (institutional absorption visible)
• CVD inflection: cumulative volume delta turns positive after being negative during the pullback (sellers exhausted, buyers taking control)
• OI holds or rises during pullback: OI did not decrease during the retracement (longs held, not closed — conviction maintained)
• Bid depth rebuild: l2Book bid depth within 0.5% of price has returned to > 90% of its pre-pullback level

Require at least 1 confirmation signal. If 2+ signals align at the same level, apply a 1.2× size bonus (max 1.2× base, never exceed risk budget regardless).

Step 4 — Entry Execution

In an established trending market, use limit orders, not market orders, to capture the pullback without paying the spread:

# Place limit order grid at the target fib zone:
limit_entry_primary   = fib_500            # centre of optimal zone
limit_entry_secondary = fib_618            # secondary fill if primary misses

# Order split:
primary_order_size   = adjusted_size * 0.65
secondary_order_size = adjusted_size * 0.35

# Cancel secondary if primary fills and price reverses past fib_618:
secondary_cancel_trigger = fib_618 - (trend_leg_size * 0.02)

Set a GTC (good-till-cancelled) limit with a 4h expiry. If price does not pull back to the target zone within 4h, cancel and reassess — chasing an extension that has already run past the entry zone is a breakout buy, not a pullback buy, and carries a different risk profile.

Position Management in Trend

Stop Placement

# Hard stop: below trend invalidation level
stop_loss = trend_invalidation  # 5% below prior swing low

# Soft stop (close position, do not use stop-limit in cascade risk):
# Close manually if 1h candle closes below swing_low_prior

Use the hard stop as a worst-case catastrophic protection only. The soft stop (manual close on 1h candle close below swing low) should fire first in normal market conditions. Hard stops placed too close inside the cascade zone will be hunted; place them clearly below structural support.

Take-Profit Structure

In a trending regime, partial profit-taking outperforms single-target exits because trends can extend far beyond initial projections:

# Measured move projection from entry:
leg_extension_100 = entry_price + trend_leg_size * 1.000   # equal leg
leg_extension_127 = entry_price + trend_leg_size * 1.272   # 1.272 extension
leg_extension_162 = entry_price + trend_leg_size * 1.618   # golden ratio extension

# Profit-taking schedule:
tp1_size = position_size * 0.35   # at 1.0× extension — lock in base profit
tp2_size = position_size * 0.40   # at 1.272× extension — core profit
tp3_size = position_size * 0.25   # trail remainder; close at 1.618× or trend break

After TP1 fires, move stop to breakeven on the remaining position. After TP2 fires, trail stop to prior 4h swing low to ride the remainder.

Trend Continuation Check (Every 4h)

def trend_still_valid(candles_1h: list, oi_now: float, oi_4h_ago: float,
                      funding_1h: float) -> bool:
    hh_hl_count = count_higher_high_higher_low_sequences(candles_1h[-24:])
    oi_rising   = oi_now >= oi_4h_ago * 0.98     # allow 2% OI noise
    funding_ok  = funding_1h < 0.03
    return hh_hl_count >= 2 and oi_rising and funding_ok

# If trend_still_valid() returns False:
#   - Do not open new positions
#   - Move existing stops to breakeven
#   - Re-evaluate regime classification

Regime Transition Handling

Bull → Exhaustion Signals

When ANY of the following appear, demote regime to EXHAUSTED and apply corresponding entry restrictions:

• Price makes a new high but OI does not confirm (OI flat or declining at new price high = distribution, not accumulation)
• Funding rate crosses above 0.03%/h and holds for 2+ intervals
• A higher high is made but volume is declining on the breakout candle (volume divergence — weakening buying pressure)
• Price closes back inside a prior consolidation range after a breakout attempt (false breakout — likely regime change)
• The prior swing low is breached on a 1h close (HH/HL structure broken)

Bull → Post-Cascade Re-Entry

When the liquidation-cascade-risk skill's CRITICAL protocol fires and flattens all longs during an active trend, this skill governs re-entry once the 5 post-cascade criteria are met (see liquidation-cascade-risk):

• Re-enter using nascent trend sizing (0.4×) initially
• Rebuild to full size only after 2 new HH/HL sequences are confirmed post-cascade (trend has re-established, not just bounced)
• Apply the same Fib entry framework from the post-cascade swing low as the new trend anchor

---

Failure Modes to Avoid

• Chasing breakouts at trend extension: Entering at the moment of maximum bullish sentiment — new ATH, parabolic move, social media euphoria — is the single most common trending-market loss. The setup is already priced; the reward-to-risk has collapsed. Wait for the pullback.
• Using a single Fib level as a hard entry without confirmation: Price touches fib_618 dozens of times in a trend without reversing. The Fib level is a zone of interest, not a guaranteed bounce. Confirmation signal is mandatory.
• Ignoring OI divergence: A price uptrend with declining OI is short-covering, not genuine bull accumulation. Short-covering rallies exhaust faster and reverse sharper. Always check OI direction matches price direction before classifying as trending bull.
• Setting stops inside the OI cluster / liquidation zone: Stops placed just below a round number or prior swing low will be taken out by stop-hunt wicks before the real trend resumes. Invalidation level must be placed below the structural zone, not inside it.
• Continuing to apply trending-bull entries after regime demotes to EXHAUSTED: Once OI diverges from price or funding exceeds 0.03%/h, the trending-bull playbook no longer applies. Defer to high-funding-carry-avoidance and liquidation-cascade-risk skills.
• Over-trading pullbacks in a nascent trend: In a nascent trend (< 3 HH/HL sequences), each pullback has a significant probability of being the final leg before reversal. Size accordingly (0.4×); do not apply full trending-bull sizing until the trend is established.

---

Integration with Risk Controls

• Max single-position size: trending-bull entries are capped at the standard Kelly/risk-budget output from kelly-position-sizing-perps. The Fib size multipliers in this skill are applied on top of that calculation, never as a bypass of risk limits.
• Concurrent positions: if trending-bull setups are active on multiple correlated assets (e.g. BTC + ETH both pulling back simultaneously), total correlated exposure must not exceed 2× single-asset risk budget. Scale individual sizes proportionally.
• Session pause after stop-out: if the trend invalidation stop fires, pause all new trending-bull entries on that asset for 1h. A stop trigger means the trend thesis is invalidated; re-entry requires a fresh HH/HL sequence to re-establish, not an immediate re-entry hoping the stop was a wick.

After entry:
  TP1 fires? → Move stop to breakeven.
  TP2 fires? → Trail stop to prior 4h swing low.
  1h close below swing low? → Close remainder immediately.

HyperLiquid-Specific Notes

• Mark price for Fib calculations: Use assetCtxs[i].markPrice as the reference price for all Fibonacci level calculations, not the mid-price from l2Book. Mark price is oracle-weighted and more stable; mid-price can be manipulated by thin-book prints during low-liquidity periods.
• OI data cadence: assetCtxs OI updates on every REST /info poll (recommended poll interval: 10s). For real-time OI trend confirmation, use the WebSocket activeAssetCtx subscription which pushes on any change rather than polling.
• Limit order placement: HyperLiquid supports post-only limit orders (tif: "Alo" in the order object). Use "Alo" for all pullback entries to guarantee maker rebate and avoid accidental market-order fills during volatile pullback candles.
• 1h candle construction: HyperLiquid does not natively serve OHLCV candles via the public API at time of writing. Construct 1h candles from the trades WebSocket feed or use candleSnapshot if available in the current API version. Validate candle source before applying HH/HL detection logic.
• Cross-margin stop execution: In cross-margin mode, stop-loss orders are executed as reduce-only limit orders. During a fast cascade, these may not fill. Pre-position the soft stop as a monitored alert with a manual market-order close, not as a resting order, to ensure execution in adverse conditions.
