Supply & Demand Desk supply & demand indicator for TradingView

A directional departure after an opposite candle creates the zone at its first close. Default bounds use the base's full range, extended only by a lower departure wick for demand or a higher one for supply. The edge facing the departed price is proximal; the far edge is distal. At the first pullback candle, the move must have reached at least 0.8 ATR beyond proximal, using ATR frozen at the zone's birth.

Its pre-retracement extreme becomes a fixed break level. At least two retracement bars must finish before a later strict close breaks that level. The breakout candle cannot count as the second retracement. Front liquidity must remain outside the zone and in the nearer half of the departure.

These thresholds and the optional FX wick adjustment are original formalizations. Five-minute standard candles are required; other chart types do not produce valid conditions.

After readiness, price must pass front liquidity and actually intersect the zone. Demand then needs a bullish close strictly above proximal; supply needs a bearish close strictly below. An opposite-color rejecting candle can wait, but a close on the adverse edge invalidates first.

The deepest wick is tracked from first visit through confirmation. Visit age zero through three is allowed; age four expires. A zone has one condition, even if plan admission is blocked. There is no automatic re-entry.

In the lesson, entry 108 minus stop 101.75 gives initial risk 6.25, called 1R. Four times that distance is 25, so the 4R target is 133. This is distance before costs, not a chance of winning.

Entry is the confirming close reference. Stop sits beyond the deepest visit wick by at least one tick; optional ATR padding increases that distance. Stop and target round outward to the instrument's tick grid. Default target is four initial risk distances away.

A reference plan cannot exit on its entry candle. On later bars, an open already beyond a reference uses that open. Otherwise touching both stop and target records an ambiguous STOP. A 48-bar hold deadline checks ordinary outcomes before a close-based time exit. No trailing, breakeven move or partial profit is assumed.

Projected net-at-target includes estimated costs. Nonpositive projection does not automatically block admission in this version. It is a scenario calculation, not an expectation or probability.

Only one paper plan is active. The optional chart-local trend filter runs first: long needs HH+HL, short LH+LL, from two-left/two-right confirmed swings. It defaults off; neutral or unavailable structure blocks when enabled. Opposite trend-eligible conditions then conflict before geometry selection. Same-side conditions choose the smallest valid risk distance, then the oldest zone.

Bad metadata, zero rounded quantity or unusable risk also blocks admission. A plan that exits on this bar cannot be replaced on the same bar. No condition is recycled after it is consumed.

A zone touched after departure but before readiness is invalidated. Total age 120 is allowed; age 121 expires. Retracement age 20 is allowed; age 21 expires before a breakout, measured from the first retracement bar. Malformed observed OHLC clears pending setups and ends an active reference as unpriced DATA GAP.

Ages count observed bars. Missing timestamps do not create invented candles. The desk retains at most 32 zones: it removes the oldest ended zone first, or the oldest live zone if none has ended. It keeps six ended paper plans. Inputs and loaded history can change a recalculated result; display controls do not change the engine.

The Lab submits its bracket with the signal and normally fills at the next available open. It owns its position and deadline independently of paper outcomes. A partial margin exit keeps the remaining position's bracket.

Defaults include 100,000 initial capital, fixed risk 100, 90-percent equity notional cap, 0.05-percent commission per side and one tick of slippage. Actual broker fills, currency conversion, gaps and costs can differ from chart references. Configure Properties for the instrument and inspect complete outcomes.

Choose Paper entry reference when you want an accepted entry, rather than Zone condition confirmed for every qualifying condition. Paper reference ended is the separate final-outcome condition. Any alert() function call provides the structured lifecycle message. Recreate alerts after source, symbol, timeframe or input changes.

Indicator reference alerts are not broker fills. Lab order-fill notifications are a different stream. This page creates no alert and proves no notification delivery.

The interactive lesson explains a stated hypothesis using fictional candles. It does not measure a trading edge. The download record pins the exact source and actual chart images. Compilation, synthetic cases, real chart checks and broker reconciliation are distinct software checks; none establishes an economic advantage.

The untouched MNQ Strategy Lab sample in the release checks lost money after declared costs. That sample does not establish future performance; it is a reason to inspect losing trades as well as the entry logic. No private indicator parity, success probability or automatic profitability is claimed.
