What the 3 Level ZZ Semafor TRO Modified Indicator does on the chart

Also, the 3 Level ZZ Semafor TRO Modified Indicator is a variant of the standard 3-level semafor with one addition: a grey DOTTED midline between the most recent level-3 swing high and level-3 swing low. Also, still, the midline acts as a 50% Fibonacci retracement reference between the last major swing extremes – traders use it as the dividing line between premium and discount price zones.

Khaki dots = level-1 small swings. Thus, orange dots = level-2 medium swings. Royal blue dots = level-3 major swings. In practice, the grey dotted line auto-updates as new level-3 highs and lows print.

• Level 2 orange dots – 4-bar fractal

• Auto-drawn 50% midline between most recent level-3 high and low
• Use the midline as your premium/discount reference
• Full alert system: popup, push notification to mobile MetaTrader, email, and sound — all four channels can be toggled independently from the inputs panel. Alerts fire once per closed bar so you never get spammed mid-tick.
• Built for both MT4 and MT5; works on every timeframe and every symbol your broker offers.
• Lightweight code that does not slow down the chart.

How to read signals from the 3 Level ZZ Semafor TRO Modified Indicator

Use the midline as a bias filter: price above midline = discount zone for shorts, below = premium for longs.

Entry idea (long). Wait for a blue level-3 dot below a bar AND price below the midline (discount territory).

Entry idea (short). Wait for a blue level-3 dot above a bar AND price above the midline.

Hence, Exit idea. Target the opposite extreme of the most recent level-3 swing range.
