█ OVERVIEWL2 Trend Guard Oscillator turns a normalized price-position reading into a clean
zero-line momentum oscillator that flags long and short pressure on any symbol and
timeframe. Every signal is state-aware, so entries, exits and ATR-based protective
levels stay consistent instead of flickering bar after bar.
█ CONCEPTS
The oscillator answers one question: is price being pushed up or down relative to its
own recent range?
• Defense line — typical price measured against the recent high-low range and
smoothed with a slow EMA; the trend guard.
• Trigger line — a faster EMA of the defense line.
• Oscillator — defense minus trigger. Above zero = short-term pressure building,
below zero = fading.
Zero-line crossings are the raw signals. The red mirror line is the negative of the
oscillator: it only makes the up/down symmetry readable at a glance.
█ HOW TO USE
1 — Add the script to any chart. It opens in its own pane with a dashed zero line and
never rescales your price chart.
2 — Rising above zero = long pressure, falling below zero = short pressure.
3 — Trade the labels, not the wiggles:
• L (green, up) long entry, S (red, down) short entry
• XL / XS (orange cross) closed by the opposite signal
• XL-TP / XS-TP or XL-SL / XS-SL closed by the ATR target or stop
• XL>S / XS>L flip: closed and reversed on the same bar
4 — The dashboard shows position, entry, stop, target, ATR, MTF gate and cooldown.
5 — Right-click the chart to create an alert; five conditions are exposed.
█ INPUT PARAMETERS
Signal Engine
• Defense Base Lookback (34) — range window used to normalize price.
• Defense EMA (8) / Trigger EMA (5) — smoothing; smaller values flip faster.
Signal Governance
• State Machine + Exclusivity — blocks duplicate and same-bar contradictory signals;
off returns the raw, unfiltered behaviour.
• Cooldown Bars (3) — minimum bars between two signals, 0 disables it.
• V1 Zero-Zone Sell (off) / Zero-Zone Width (1.0) — optional legacy sell while the
oscillator sits just above zero on a down bar; noisy in ranges.
Risk and Filters
• Enable ATR TP/SL (on), ATR Length (14), Stop Loss x ATR (2.0), Take Profit x ATR (3.0).
• Enable HTF Trend Gate (off), HTF Timeframe (240), HTF EMA Length (50) — longs only
above that EMA, shorts only below it; must be higher than the chart timeframe.
• Show Labels, Show Background, Show Dashboard, Label Size, Enable Alert Conditions.
█ SIGNALS
• L / S entries, XL / XS exits, XL-TP / XL-SL and
XS-TP / XS-SL ATR exits, XL>S / XS>L flips.
• A light green or light red background marks the open position.
• The data window exposes defense line, trigger line, position state, stop and target.
█ IMPLEMENTATION NOTES
• EMA smoothing, range normalization and ATR; signals come from zero-line crossings,
not level comparisons.
• The optional higher-timeframe gate reads the previous closed bar with lookahead on,
so it does not repaint.
• Signals and alerts are confirmed on bar close.
█ LIMITATIONS
• Momentum lags by design: the first leg of a sharp reversal is missed.
• Ranges still produce zero-line whipsaws; raise Cooldown Bars or keep the MTF gate on.
• ATR exits are evaluated on bar highs and lows, so labels mark the touch bar, not a
fill price.
• Best on liquid symbols, 5-minute timeframes and above.
█ NOTES
• Defaults reproduce the original blackcat L2 engine; every filter is optional.
• A signal and risk-mapping tool, not a standalone trading system.
