OS Histo (MT4)

OS Histo is an overbought/oversold histogram that condenses momentum into a clean bar plot for quick bias reads, zone crosses and timed pullbacks in MetaTrader 4.

What it shows

• Histogram (0–100 / − to +) — normalized momentum with a midline for bias.
• OB/OS zones — configurable overbought and oversold thresholds.
• (Optional) arrows/alerts — entries on zone crosses, midline crosses, and slope flips.

Trade ideas

1. Trend pullback: in an uptrend, buy when the histogram pulls from OB to mid, then turns up again (mirror for downtrend).
2. First cross after regime flip: after a midline cross, take the first pullback that holds the new side.
3. Range mean‑reversion: fade exhausted extremes back toward the midline (seek confirmation).
4. (Optional) Multi‑TF: use a higher‑TF read as a regime filter.

Inputs that matter

• Period — responsiveness vs stability.
• Smoothing — reduce noise without delay.
• OB/OS levels — adapt to the asset/timeframe.
• Alerts — zone/midline cross, slope change, extremes.
• Colors/widths — fast visual read.

Suggested usage

• M5–M15: intraday pullbacks and quick reversions.
• M30–H4: swing continuations with zone filters.
• Daily+: bias/overheat read for portfolio tilt.
