Gann HiLo Histo - Clean trend activation (MT4)

Gann HiLo Histo is a trend filter derived from the Gann HiLo Activator. It paints a histogram that flips color when price closes above/below a smoothed Hi/Lo baseline, helping you ride swings and avoid chop on MetaTrader 4.

What it shows

• Up color when close is above the activator baseline, down color when below.
• Flat/alternating blocks warn about range and noise.
• Optional arrows and alerts on flip, fresh highs/lows in regime or baseline cross.
• Works as a bias map and a pullback filter.

Trade ideas

1. Flip with structure: enter with the first flip that aligns with HH-HL or LL-LH.
2. Pullback continuation: take pullbacks that do not flip the histogram against the trend.
3. Breakout confirmation: require the same color across a breakout bar and the next bar.
4. Multi TF: higher TF up color + lower TF flip gives cleaner timing.

Inputs that matter

• Period for the Hi/Lo smoothing.
• Method of smoothing (SMA, EMA, etc.).
• Price source and optional shift.
• Alerts on flip and level crosses.

Suggested usage

• M5-M15: intraday trend filter and pullback timing.
• M30-H4: swing continuation and breakout confirmation.
• Daily+: bias framework and scaling plan.
