What this strategy does

This turns BigBeluga’s visual FVG concept into an entry/exit strategy. It scans bullish and bearish FVG boxes, measures how deep price has mitigated into a box (as a percentage), and opens a long/short when your mitigation threshold and filters are satisfied. Risk is managed with a fixed Stop Loss % and a Trailing Stop that activates only after a user-defined profit trigger.

Additions vs. the original indicator

✅ Strategy entries based on % mitigation into FVGs (long/short).

✅ Lower-TF volume split using upticks/downticks; fallback if LTF data is missing (distributes prior bar volume by close’s position in its H–L range) to avoid NaN/0.

✅ Per-FVG total volume filter (min/max) so you can skip weak boxes.

✅ Age filter (min bars since the FVG was created) to avoid fresh/immature boxes.

✅ Bull% / Bear% share filter (the 46%/53% numbers you see inside each FVG).

✅ Optional candle confirmation and cooldown between trades.

✅ Risk management: fixed SL % + Trailing Stop with a profit trigger (doesn’t trail until your trigger is reached).

✅ Pine v6 safety: no unsupported args, no indexof/clamp/when, reverse-index deletes, guards against zero/NaN.

How a trade is decided (logic overview)

Detect FVGs (same rules as the original visual logic).

For each FVG currently intersected by the bar, compute:

Mitigation % (how deep price has entered the box).

Bull%/Bear% split (internal volume share).

Total volume (printed on the box) from LTF aggregation or fallback.

Age (bars) since the box was created.

Apply your filters:

Mitigation ≥ Long/Short threshold.

Volume between your min and max (if enabled).

Age ≥ min bars (if enabled).

Bull% / Bear% within your limits (if enabled).

(Optional) the current candle must be in trade direction (confirm).

If multiple FVGs qualify on the same bar, the strategy uses the most recent one.

Enter long/short (no pyramiding).

Exit with:

Fixed Stop Loss %, and

Trailing Stop that only starts after price reaches your profit trigger %.

Input settings (quick guide)

Mitigation source: close or high/low. Use high/low for intrabar touches; close is stricter.

Mitigation % thresholds: minimal mitigation for Long and Short.

TOTAL Volume filter: skip FVGs with too little/too much total volume (per box).

Bull/Bear share filter: require, e.g., Long only if Bull% ≥ 50; avoid Short when Bull% is high (Short Bull% max).

Age filter (bars): e.g., ≥ 20–30 bars to avoid fresh boxes.

Confirm candle: require candle direction to match the trade.

Cooldown (bars): minimum bars between entries.

Risk:

Stop Loss % (fixed from entry price).

Activate trailing at +% profit (the trigger).

Trailing distance % (the trailing gap once active).

Lower-TF aggregation:

Auto: TF/Divisor → picks 1/3/5m automatically.

Fixed: choose 1/3/5/15m explicitly.
If LTF can’t be fetched, fallback allocates prior bar’s volume by its close position in the bar’s H–L.

Suggested starting presets (you should optimize per market)

Mitigation: 60–80% for both Long/Short.

Bull/Bear share:

Long: Bull% ≥ 50–70, Bear% ≤ 100.

Short: Bull% ≤ 60 (avoid shorting into strong support), Bear% ≥ 0–70 as you prefer.

Age: ≥ 20–30 bars.

Volume: pick a min that filters noise for your symbol/timeframe.

Risk: SL 4–6%, trailing trigger 1–2%, distance 1–2% (crypto example).
Set slippage/fees in Strategy Properties.

Notes, limitations & best practices

Data differences: The LTF split uses request.security_lower_tf. If the exchange/data feed has sparse LTF data, the fallback kicks in (it’s deliberate to avoid NaNs but is a heuristic).

Real-time vs backtest: The current bar can update until close; results on historical bars use closed data. Use “Bar Replay” to understand intrabar effects.

No pyramiding: Only one position at a time. Modify pyramiding in the header if you need scaling.

Assets: For spot/crypto, TradingView “volume” is exchange volume; in some markets it may be tick volume—interpret filters accordingly.

Risk disclosure: Past performance ≠ future results. Use appropriate position sizing and risk controls; this is not financial advice.
