Formula Reference

Order-Book Variables

• imb / absImb: selected-depth imbalance, signed and absolute.
• deltaImb / absDelta / prevImb: candle-to-candle change and the previous value.
• l1..l10 and c1..c10: per-level and cumulative imbalance from level 1 to 10.
• bidNotional / askNotional / cumBookNotional: raw bucket and cumulative book notional.
• sameSide: whether pressure stayed on the same side as the previous candle.

Spread & Price Variables

• spreadAvg / spreadRange / spreadMin / spreadMax: spread aggregates in basis points.
• mid / bestBid / bestAsk: top-of-book prices and midpoint.
• open / high / low / close / quoteVolume / notionalM: kline fields and quote volume.
• priceRangeBps / bodyBps / closeLocation: candle range, body, and where the close landed.

Trade-Flow Variables

• takerBuyRatio / takerSellRatio / avgTradeNotional: aggression and average trade size.
• cvdHigh / cvdLow / cvdRange: intracandle cumulative volume delta.
• buyRun / sellRun: largest same-side taker run (sweeps).
• tradeMaxBuy / tradeMaxSell: largest single taker print (whale orders).
• sweep: the bar’s dominant taker event in quote notional — the larger of the biggest single print and the longest same-side run, on whichever side is bigger. This is the exact quantity the chart’s Sweeps layer ranks.
• sweepBuy / sweepSell: that same magnitude for each side on its own. sweepSide: +1 when the buy side dominated, -1 the sell side, 0 on a quiet bar.
• cvdClose: session-anchored running CVD at bar close — compare with change(cvdClose, n), not as a raw level across long spans.
• tradeBuyCount / tradeSellCount: aggressor print counts per side — many small prints read differently than a few blocks.
• cascadeScore: same-side burst intensity versus this market’s own norm — the forced-flow proxy on Hyperliquid (available on 1m/5m/15m bars).

Derivatives & Microstructure Variables

• funding / fundingBps: perp funding rate; positive means longs pay shorts.
• basisBps / markPremiumBps: mark versus last trade and index.
• oi / oiDelta / oiDeltaPct: open interest and its change.
• liqBuy / liqSell / liqNotional / liqDelta: liquidation notional by side, total, and net — not populated on Hyperliquid (no public market-wide liquidation feed).
• ofi, microprice / micropriceBps: order-flow imbalance and size-weighted fair value lean versus mid.
• premiumBps: venue basis at bar close (mark vs oracle, bps) — positive means the perp is trading rich.
• impactBidPx / impactAskPx / impactSpreadBps: the venue’s own impact prices and their spread versus mid — a ready-made slippage read.
• oiHigh / oiLow: intracandle open-interest extremes — churn the close-to-close delta smooths away.
• bidOrdersL1 / askOrdersL1: resting order counts at the touch — big size in one or two orders is the classic fake-depth tell.

Statistics & Universe

• p / z: percentile and z-score of pressure versus recent history.
• rank: trailing-volume rank across the Hyperliquid market universe.
• age: seconds since the candle, for freshness filters.
• btcRet / betaBtc / residBps: BTC’s bar return (bps), the market’s rolling 60-bar beta to BTC, and the residual — this bar’s return minus its beta-implied BTC component. residBps isolates a market moving on its own rather than with BTC.

Functions

• Math: abs, max, min, avg, clamp, round, floor, ceil, sqrt, ln (natural log; non-positive inputs yield no value rather than firing).
• Lookback (window 1-200 candles): prior(x, n), change(x, n), highest(x, n), lowest(x, n), sma(x, n), sum(x, n), stdev(x, n). Example: imb >= highest(imb, 50) — or a self-relative z-score of any expression: (imb - sma(imb, 50)) / stdev(imb, 50) >= 2.
• median(x, n): the middle value over the last n candles. The robust baseline — a single outsized bar drags an average but not a median, so prefer it for notional metrics like sweeps and liquidations.
• pctRank(x, n): where this candle’s x sits within its own last n candles, from 0 to 1 (1 = the highest of the window). This is how you say “big for THIS market” without picking a dollar threshold that fits BTC and misses everything else. Example: pctRank(sweep, 120) >= 0.94 fires on the top 6% of sweeps for whatever market it is scoring.
• Indicators (period 2-200, on any series): rsi(x, n), ema(x, n), macd(x), atr(n). Example: rsi(imb, 14) <= 25 finds order-book "oversold".
• count(condition, n): how many of the last n candles met a condition. Example: count(oiDelta > 0, 5) >= 5.
• Cross-sectional (this symbol vs the whole scanned universe, at the same bar): xsRank(x) percentile 0-100 vs the field, xsZ(x) z-score vs the field, xsMedian(x) the field’s median. Example: xsRank(ofi) >= 95 fires only when a market’s order-flow imbalance is in the top 5% of every market scanned right now.
• deseason(x, n): hour-of-day deseasonalized z-score — how unusual x is right now versus its own history at the SAME time of day, over the last n candles. Stops a market that always moves at the US open from looking “unusual” just because it’s the open. Needs several days of same-hour history, so it’s most useful on 1h and higher intervals; on short intervals it abstains rather than guess. Example: deseason(imb, 200) >= 2.

Formula Habits

Write formulas that you can explain after a volatile candle. If a formula is impossible to reason about during live review, simplify it before trusting the output. The in-app reference (the docs button on the desk) lists every variable with its exact definition.
