Strategy [High-Low Cloud Trend] (v6, perf-safe)

Description
High-Low Cloud Trend Strategy (Performance-Safe Edition)
Version 6 • RezzoRedPriest (based on the original logic by rottor29)

How it works
Dynamic range ― The script tracks the highest high / lowest low over a look-back of N bars (len). When price tags one extreme, a “pivot” flips to the opposite extreme, forming the core of the cloud.

Trend filter ― If the candle closes above the pivot, trend = bullish; below it, trend = bearish. The optional “Trade only with trend” switch forces longs in bullish mode and shorts in bearish mode.

Signals

Cloud Retest – price pulls back to the inner edge (band1) and rejects it.

Cloud Cross – price breaks through the outer edge (band).

Mean Reversion – spikes beyond the inner edge and snap back (optional).

Execution model – trades are processed once per bar (process_orders_on_close = true), capped at maxTradesPerDay.

Performance guardrails

Only the most-recent visBars bars are calculated and painted.

Object limits: max_labels_count = 400, max_lines_count = 30.

Recommended use
Works on any timeframe; common sweet spots are 5 m & 15 m for liquid futures / FX.

Increase len for higher timeframes (e.g. 55–100 on 1 H) to avoid noise.

If your chart still lags, either:

Lower Drawings: show last N bars, or

Turn Show cloud fill off – the fill is the heaviest operation.
